How Much Does HVAC Installation Cost?
- Installing a new HVAC system ranges on average from $5,000 to $12,500.
- Several factors influence your HVAC replacement cost, including the size and layout of your house, the reusability of the ductwork, the system’s energy efficiency and the complexity of the project.
- You can consider taking out a personal loan, home equity loan or a HELOC or to finance your HVAC replacement.
A heating, ventilation, and air conditioning (HVAC) system controls the heat, humidity and air flow inside a building. It acts like your home’s respiratory system, regulating the temperature to keep the house cool in summers and warm in winters, cleaning the air, and maintaining the right amount of air moisture. Most HVAC systems have a lifespan of 10 to 15 years, and some can even last for 20.
However, when your HVAC conks out, getting a new one won’t comes cheap. According to Angi, the contractor-search site, the average cost of a new HVAC system nationally runs about $7,500 but can range anywhere from $5,000 to $12,500, reflecting the system’s size, style and brand, along with your home’s size and layout. Much depends on its ductwork, too — how much needs to be replaced or augmented.
Still, HVAC systems are necessary: A broken or poorly functioning one can cause your heating and cooling bills to skyrocket — not to mention making your home rather uncomfortable or even unhealthy to inhabit. While pricey, replacing a HVAC system does not have to be stressful if you take the time to learn the ins and outs, including the potential cost and how to finance the project.
The cost of HVAC installation by unit type
Air conditioning systems vary widely in cost, depending on the unit type. On the cheaper end of the spectrum, there are self-installed window units and portable units, which you can find for less than a few hundred dollars in some cases. However, if you want something more advanced that can cool down a larger area (like a split system or central A/C), you can expect to pay at least a couple thousand dollars.
|A/C unit type||Cost (including installation)|
|Window and portable units||$150 – $500|
|Ductless split system||$2,000 – $14,500|
|Central air conditioning system||$1,900 – $5,500|
Furnace prices also vary based on the type of fuel that they use. In general, the most affordable options are electric furnaces, followed by natural gas and oil furnaces.
|Furnace type||Cost (including installation)|
|Electric furnace||$1,600 – $6,900|
|Natural gas furnace||$3,800 – $10,000|
|Oil furnace||$6,750 – $10,000|
Heat pump costs
Having a heat pump installed will set you back anywhere from $1,300 for a mini-split heat pump to $40,000 for a supplemental electric one. Other types, including air source and geothermal heat pumps, fall somewhere in the middle.
|Heat pump type||Cost (including installation)|
|Air source||$4,500 – $8,000|
|Geothermal||$6,000 – $20,000|
|Mini-split||$1,300 – $8,000|
|Hybrid||$2,500 – $10,000|
|Solar||$18,000 – $34,000|
|Supplemental electric||$2,500 – $40,000|
What influences HVAC installation costs?
A HVAC system consists of two basic elements: the heating/cooling units themselves (furnace, air conditioner, etc. ) and the ductwork, the system of tubes that circulate the air throughout the house. Replacing a HVAC system can involve one or both, and it makes a difference, price-wise. According to HomeGuide.com, the average cost to replace the HVAC units is $5,000 to $11,000; to replace the units with ductwork runs between $7,000 and $16,000 in total.
The larger your home, the more square footage the HVAC system will need to heat or cool. The size of the unit installed is determined by the amount of square footage of your home, and if your home is large, you may need more than one HVAC unit to cover it.
Your home’s construction also plays a critical role in what HVAC system you need. If you have adequate insulation you may be able to get away with a unit that has less air conditioning and heating capacity. Improper or inadequate insulation means that the HVAC system will need to work much harder to keep your home cooled or heated, and you may need a unit with more heating and cooling capacity.
If a HVAC system acts as your house’s lungs, then its ductwork — the tubes that transport the heated or cooled air throughout the home — are its veins and blood vessels.
Ductwork is priced by quantity and averages around $15 per linear foot, says Mallory Micetich, a home expert at Angi. “The average total cost will depend on what material you choose, whether you need to add vents, the size and layout of your home, where you live, and the accessibility of any existing ductwork,” she says. You may also pay extra to have the ducts encased and hidden.
It is possible the existing ductwork in your home will be sufficient for a new HVAC system. However, if your ductwork does need to be replaced or extended, you should expect to see significant extra costs — it’s often the most labor-intensive part of the job. New ductwork alone can add up to $5,000 to your bill, according to HomeGuide.
Brand of HVAC unit
The brand of the HVAC system you select may have a significant impact on equipment cost, installation cost and warranty. Some of the most common HVAC system brands on the market today include:
- Magic Pak
SEER stands for Seasonal Energy Efficiency Ratio, which is the rating that results from the ratio used to measure a system’s energy efficiency. The higher the SEER rating, the more energy-efficient the system will be and the more money you’ll save on utility bills each year. Units with higher SEER ratings cost more, though, and if you live in a moderate climate, it may not make financial sense to spend more on a system with a higher SEER rating.
HVAC systems that are harder to access or older homes that require modifications or custom parts will likely result in higher HVAC replacement costs. Something to keep in mind when you’re shopping for that Victorian Gingerbread manse or Art Deco-era bungalow.
HVAC installation costs: prices for different parts
Along with the overall HVAC system — new air conditioner, ductwork, and furnace — you will have a variety of optional upgrades or add-ons. Many HVAC companies offer extras like dehumidifiers, air purifiers, zoning systems, smart thermostats, carbon monoxide alarms and UV lamps.
If you would like such additional components, your HVAC system cost will likely be even higher — as high as $9,500 to $18,500, according to HomeGuide. Some details on different ones:
Air purifiers can be a great option for improving indoor air quality in your home. “There are various sizes and prices available on the market, so think about what works best for your home,” says Micetich. Costs can range from $100 to thousands of dollars, depending on size, brand, noise level and various other features.
Installing a whole-house dehumidifier can range in cost from $1,300 to $2,800, averaging around $2,000. “Basement models range from $1,300 to $1,800 and crawl space models are closer to between $1,500 and $2,000,” says Micetich. “The cost range depends on the unit capacity, brand, accessibility of the installation area, and whether you decide to add a designated outlet or return duct.”
Smart thermostats are typically more expensive than traditional alternatives, costing between $120 and $260, depending on the brand, special features and difficulty of installation. This will often be money well spent, however, as these types of thermostats can save you money over the long run.
“Make sure you invest here, smart thermostats can help to save you money by helping you learn about your habits, such as when you leave, when you return, optimizing energy usage and most importantly, vacation modes and the ability to turn on or off your system when you’re on your way to or from home,” says David Steckel, a home expert with Thumbtack.
Homeowners are seeing the benefits of lower electricity bills and cleaner air by adding UV lights to their HVAC systems. New bulbs for these types of lamps start at around $100 per bulb and generally need to be replaced each year. “For new parts and installation, you could see a total cost of up to $1,500,” says Micetich. “This seems expensive but will ultimately save you money on monthly bills and help keep your family healthier, especially if you live in an area with poor air quality.”
Tips for saving on HVAC installation
You may be able to save money on replacing your HVAC system by using one or more of the following methods.
Find the right HVAC size for your home
Speak with more than one professional to help determine an adequately sized HVAC system for your home and needs. Make sure that your HVAC specialist recommends the purchase of a system big enough to meet your comfort level and desires, but avoid spending the extra money to purchase one bigger, or with more bells-and-whistles, than you’ll realistically require.
“Research the different options and talk to the HVAC pros about what might work best for your home based on its size, age and layout,” says Micetich. “Some systems will be more challenging to install in multi-level homes or homes without existing ductwork, so consider what makes sense for your space.”
Get multiple quotes
Find an HVAC installer who is fair and upfront about price, but don’t just go for the cheapest. You’ll want the best work for the least money, not the least work for the least money. If you try to cut corners, you could be facing repairs well before you’re ready to.
“Get at least three estimates and don’t be shy about asking as many questions as you’d like,” says Micetich.
Ask around for referrals and references. All companies are not equal, especially when it comes to the customer service they offer. If an HVAC company has a reputation for terrible customer service but offers you the lowest replacement cost, you may end up spending more in the long run (not to mention the extra time, effort and hassle).
“Research various local HVAC pros and check out their ratings or reviews online,” says Micetich. “Many high-quality pros will come to your home to check out the issue in person before providing a detailed estimate. You can help ensure the estimate is accurate by understanding your system and providing as many details as possible about the current system, what you need done, what work has been done in the past and any issues you’ve been having.”
Keep things up to date
Replace air filters regularly. And even if your system seems to be functioning fine, start thinking about replacement after a decade or so — the midpoint of its (most generous) lifespan. Odds are, a new, more energy-efficient model or features now exist. Upgrading some parts of the system will be cheaper than an overall overhaul, and might be enough to stave off a breakdown.
HVAC financing options
Once you’ve determined who you want to hire to replace your HVAC system, determine how you will pay for the replacement. If you don’t have $5,000 to $12,500 in your bank account waiting to be spent, you’re not alone. There are plenty of HVAC financing options available to help you foot the cost of the bill.
Home equity loan
If you have built up significant home equity (the difference between what you owe on your mortgage and what the home is worth), a home equity loan for your HVAC replacement might work well. Using your home as a collateral, banks will allow you to borrow a percentage of the equity — usually up to 85 percent, but it can vary — and you can usually do so with low but variable interest rates and tax-deductible interest. There may be closing costs and other fees to consider with this type of loan, though, and you’ll have to have a big enough ownership stake to qualify.
Home equity line of credit
Similar to a home equity loan, a home equity line of credit (HELOC) allows you to borrow against the equity in your home; but rather than receiving a lump sum, a HELOC gives you access to a line of credit that you can borrow from repeatedly during the draw period. HELOCs usually offer a low interest rate, but the rate can fluctuate. Still, the flexibility of the withdrawals may be a great option if you have several home improvement or maintenance projects in mind, or if you aren’t sure whether the HVAC replacement will require ductwork and don’t want to have to take out multiple loans to pay for it.
Home improvement loan
A home improvement loan works like a standard personal loan and is ideal for projects such as an HVAC installation or replacement. Most banks and lending institutions offer personal loans to people who have average or above-average credit. They are quick to get approved for, have a fixed interest rate and the repayment period varies between 12 and 60 months.
On the upside, personal loans usually offer quick access to funds, which is important if your HVAC system is not functioning correctly. On the downside, you are stuck with interest payments for several months or years for even a small home improvement project. Unlike home equity financing, the interest in not tax-deductible, either.
HVAC company installment plan
Some HVAC companies offer special payment plans to customers who meet certain requirements. This type of financing can sometimes even be interest-free for a specific period. Although great for the short term, this plan can quickly become costly if you let the borrowed sum age and turn into a high-interest loan. If you consider in-house financing, go over the details and fine print with utmost care.
Final word on HVAC installation costs
Replacing an HVAC system can be a costly and complicated project. Here are some of the key steps if you plan to move forward.
- Research will help you make the best decisions. Understand what type of system will work for your home, based on its size, layout, age and existing system. If you need ductwork replaced or installed, it will probably boost the overall cost of the new system by one-third.
- Add-ons will cost you more. Additional components such as air purifiers, dehumidifiers, smart thermostats and UV lamps will push the price of your project even higher. Understand all of the variables ahead of time, as well as the value of each of these options and how they may impact your long-term costs.
- Multiple estimates can help save you money. Get at least three estimates and ask a lot of questions before signing a contract to make sure you’re working with a high-quality pro and are not faced with any major surprises along the way.
Once a new system is installed, protect your investment by keeping the system in top shape. “Just remember that your HVAC system is your home’s respiratory system, and it’s crucial to take care of it with regular maintenance,” says Steckel.
New HVAC System Cost: How Much Is It?
A new HVAC system is not a trivial investment. We asked an HVAC pro to fill us in on likely costs and how to tell if a system needs replacement.
The HVAC system plays the essential role of keeping a house warm in the winter and cool in the summer. Replacing one is a major investment, so many homeowners let it slide for longer than they should.
That’s often a penny-wise but dollar-foolish decision for two reasons. Homeowners end up paying more for repairs in the long run than a replacement would cost, and also waste money on inefficient heating and cooling.
Tim David, the CEO of Airlucent.com and an HVAC pro with more than 25 years of experience, says upgraded energy efficiency requirements from the Department of Energy are making new HVAC systems more expensive. “Consumers … should expect slightly higher costs for equipment, but better efficiency on their energy bills,” he says.
Still, HVAC system replacement is often more cost-effective than repairing an outdated system. It’s like spending thousands keeping your 20-year-old clunker on the road versus buying a modern, fuel-efficient vehicle.
According to HomeAdvisor, the national average cost for installing a new HVAC system is around $7,000, but that depends on several factors. Here are some tips to determine your costs for a new HVAC system.
Factors That Determine the Cost of HVAC System Replacement
The cost of HVAC replacement depends on where you live and the nature of the system (furnace vs. heat pump). It could range from $3,000 to $10,000. David says it costs about $3,000 to install a new electric furnace, and $5,000 to $8,000 to install a new heat pump.
“With the subsidies now in place for upgrading your home to be more energy efficient, you can claim up to $2,000 as a write-off,” says David. “And if you upgrade your insulation/windows, that could be another $1,200.”
It should be noted the $2,000 subsidy applies only to heat pumps. It’s part of the federal government’s move toward electric home heating methods.
If you already have a gas furnace and it makes sense to continue using gas, replacing your furnace will range from $3,800 to $10,000, or slightly higher if you opt for a high-efficiency model. If you heat your home with oil, furnace replacement will run between $6,750 and $10,000. These costs are determined by:
- The brand of equipment;
- The size of your home’
- Your climate zone;
- The local cost of labor.
Signs That It’s Time for a New HVAC System
David says it’s time for replacement when your system is at least 15 years old, and you have to call out an HVAC tech at least once a year for three consecutive years.
Both conditions indicate the system is functioning at a lower efficiency it should, wasting energy and money. David also notes if a single repair approaches 50% of the cost of a new system, you should just replace it.
“Most likely, something major is going on,” says David. “And if you don’t replace the whole thing, then you could be adding unnecessary stress to other older parts that don’t get replaced.”
DIY vs. Hiring Pros
It’s technically possible for a homeowner to DIY an HVAC installation, but David doesn’t recommend it. “HVAC systems are complex, require permits and specialized tools, and involve safety hazards,” he says. “Improper installation can result in poor performance, higher energy bills, and safety hazards for homeowners and their families.”
Another problem with DIY installation: It may void the product warranty. Most HVAC parts manufacturers require installation by licensed HVAC contractors for the warranty to be valid.
“Even if you have the necessary skills, although you will be able to save on labor costs, DIY installation can result in unforeseen additional costs due to mistakes, safety hazards, and the need to hire a professional to fix any issues that arise,” says David.
Questions To Ask HVAC Contractors
With government subsidies for HVAC upgrades now in effect, an HVAC contractor is the best person to advise you on how to take advantage of them. You can ask questions like:
- Is my home a good candidate for a heat pump?
- I want to continue using gas. Is it worth it to upgrade to a high-efficiency furnace?
- Will it make any difference to my comfort level and energy bill if I spend more money for a system with a higher efficiency rating than the minimum required?
- Will this HVAC replacement involve any changes to other components of the system, including the air handler and ductwork?
Of course, before hiring any contractor, always verify licensing and how long they’ve been in business. To avoid overcharging or substandard service, it’s also a good idea to check references and reviews on social media.
Air conditioning of a private house
Air conditioners Mitsubishi › Air conditioning of a private house
Air conditioning of a private house or cottage is an issue that should preferably be addressed at the construction stage. We will tell you what you should pay attention to when choosing an air conditioner for a suburban building, and what type of system is better to prefer.
Features of air conditioning in a private house
When choosing an air conditioning system for a country house, consider:
- system power. This parameter is selected according to the dimensions of your building. In this case, it is worth taking into account all sources of heat, general illumination and the number of permanent residents. Because if the capacity of the air conditioning systems for the house is excessive, then the electricity will increase. And if, on the contrary, the power is not enough, then the air conditioner will no longer cope with the tasks. That is why experts calculate the power.
- system energy efficiency. The higher this parameter, the more expensive the air conditioner will cost you. But at the same time, the higher the energy efficiency of the installation, the less energy consumption will be.
- compressor type. The right solution for a cottage is an inverter compressor. This type of economically consumes electricity, is characterized by silent operation and smooth adjustments. If we are talking about small air conditioners for a country house, where you visit only in the summer, give preference to non-inverter installations.
- air intake function. The best option, if your house is built in an ecological place, would be to have a function not of filtration, but of air intake.
- exterior and interior. The split system will inevitably affect the exterior and interior of the house. Consider in advance where you will install the indoor and outdoor units. Or maybe you’d install a channel or cassette system where the blocks aren’t as visible?
Choosing the type of air conditioner
There are several options for air conditioning systems for cottages and private country houses. The most optimal of them is the installation of multi-zone air conditioning system . The system consists of one or more outdoor units, each of which is connected, depending on the manufacturer and model, from 2 to 30 indoor units. Outdoor units are placed mainly on the roof or in the backyard and do not affect the overall appearance of the building. A unique feature of multi-zone air conditioners is the ability to simultaneously operate in both heating and cooling modes: this is more than relevant when the windows of some rooms face the sunny side, while others face the shady side. At the same time, each indoor unit takes as much cold (or heat) as it needs at the moment to maintain the set temperature, which significantly saves electricity.
The advantage of such equipment is the possibility of placing indoor units on different floors and at a great distance (up to 160 m) from the outdoor one, with a height difference between them up to 50 meters – this allows you to distribute heated or cooled air to rooms located on different floors . Indoor units can be of various types: wall-mounted, ducted, cassette, which allows you to maximize the air conditioning and use for each room its own type of indoor unit of the air conditioner.
The advantage of multizone systems is the long length of the line between the outdoor and indoor units, which allows you to install the indoor unit anywhere in the room and achieve the necessary climatic conditions.
If you need to organize comfortable conditions in one or two rooms of a private country house or cottage, then you can use split systems. Split system consists of outdoor and indoor units and is the most popular air conditioning system.
Cottage, as a rule, has a place to install duct type split system , which is installed under a false ceiling or in the attic.
The design of ducted air conditioners allows you to fully preserve the design of the room: the unit is installed behind a false or false ceiling, and the distribution of cooled air is carried out through a system of air ducts, which are located there; of all the air conditioning equipment used, only air grilles are visible on the ceiling. The duct air conditioner has the ability to supply fresh air from the street in the volumes necessary for proper ventilation. There is also the possibility of adding fresh air, ventilation and humidification, which is especially important and necessary in cottages and country houses. In addition, duct-type air conditioners are able to distribute air over a large area of one or more rooms. Proper placement of indoor units of a duct-type split system will allow you to replace a whole network of air conditioners.
The only and important condition necessary for a room to be equipped with a ducted air conditioning system is the presence of high enough ceilings in it, which would allow the construction of a so-called false ceiling. Behind this false ceiling, it becomes possible to hide all the structural parts of the duct air conditioner (valves, valves, air ducts and other elements).
Often for small rooms and rooms in country houses choose wall split systems . One of the advantages is the relatively low cost and ease of installation. Recently, manufacturers of wall-mounted split systems have been actively fighting to improve their consumer properties, and first of all, of course, the design of indoor units. New air conditioners with a non-standard design appear on the climate market: square-shaped, various colors, with mirror and interchangeable color panels, etc.
A significant advantage of the wall-mounted air conditioner is the reduced noise level inside the room, since all noise emitting units (compressor, motor and fan) are enclosed in a unit that is located outside the room. This outdoor unit can be mounted either on the wall of a building or mounted on a balcony.
All modern split systems are equipped with a remote control with which you can set the desired temperature with an accuracy of 1 degree, set a timer to automatically turn the air conditioner on and off at a given time, adjust the direction of the air flow and much more.
A significant disadvantage of a split system is a large number of outdoor units, each of which corresponds to one indoor unit. But several external units with fans will not decorate any facade of a country house. What if there is a need to use air conditioners in each room in different modes?
There is only one way out of this situation – this is the installation of a multi-split system.
Multi split system differs from the classic split system in that one external condensing unit in this case can serve several (from two to six) indoor units simultaneously. At the same time, the device and the principle of operation of the system remain unchanged – the external and internal blocks are connected by the so-called freon routes, consisting of copper pipes for supplying refrigerant, a drainage pipeline, as well as power and control cables.
Each indoor unit has its own remote control for selecting individual air conditioning settings for each room.
The indoor units of a multi-split system can be of the same type (wall, floor, etc. ) or combined depending on the technical characteristics of the room, interior design considerations.
Blocks may also differ in technical characteristics, depending on the requirements for the required temperature regime for a given room.
The multi-split system not only simplifies the management of the entire air conditioning system, but also reduces energy consumption by almost half, thanks to inverter-controlled outdoor unit compressors.
Parameters for choosing an air conditioner for a country house
When choosing an air conditioner for a country cottage or a private house, it is recommended to pay attention to some important parameters.
Main selection criteria:
- Appliance power with room area calculation.
- Noise level during operation. The most powerful devices are very noisy, therefore they create a characteristic discomfort for households, especially at night. The lowest and optimal noise level is 20-24 dB.
- Reliability of climatic equipment. High-quality air conditioners from trusted manufacturers are more expensive, but they will also work for a longer period, doing their job perfectly. Cheap Chinese equipment quickly breaks down, which will entail additional costs for repairs or the purchase of new equipment.
- Air purification system. Pay attention to which filters are installed in the device.
- Compressor type. For a country house, the best solution would be an inverter model.
- In order to prevent the formation of a pathogenic environment in the air conditioner unit after each shutdown, which contributes to the appearance of mold, choose a model with a built-in self-cleaning system.
- The self-diagnosis function also does not interfere.
- If you plan to use the unit all year round, purchase a model with two operating modes – cooling and heating. Additional functions of the air conditioner – exclusively at the request of the buyer.
An important criterion for choosing an air conditioner for a private house is the method of installation. If the design of the interior rooms allows for hidden installation of equipment units, you can opt for a highly efficient and aesthetic ducted air conditioner.
Multi-split systems consist of a variable number of units and are designed for wall or floor mounting. Determine in advance which installation option is most convenient for you.
Solutions for maintaining the exterior facade of a house
The use of a multi-split system or a multi-zone system is justified if you do not want to spoil the appearance of the facades of your house. The difference between the above air conditioning systems in a private house is that in the case of using a multi-split system, a separate freon line goes from each indoor unit to the outdoor unit, and in the case of a multi-zone system, one common freon line goes from the outdoor unit with branches to the indoor units. blocks.
When installing ducted air conditioners in a house, it must be remembered that for the distribution of air ducts in rooms and the installation of gratings, it is necessary to allocate space for a false ceiling. In this case, you only see the air distribution grilles. It is also possible to cool the air in the house with one powerful ducted air conditioner (for example, one unit per floor), or installing separate indoor units for each room separately (if space permits). The disadvantage of using one powerful unit is that it is not possible to control the temperature in each room separately, since there is only one control panel. The use of several duct-type indoor units increases the cost of the system itself, but the feasibility of using such a combination is a reasonable decision.
Why is it necessary to design an air conditioning system before starting repairs?
At first it may seem that design is a step that can be missed and thus saved. But we are sure that such an opinion is wrong and here are the reasons why the design of an engineering system should be carried out before the start of repair work:
- Only under such conditions can engineering communications be included in interior design.
- Budgeting. Design will allow you to see the exact estimate of the project before the start of installation work. Thus, you can choose a system within the strict limits of the allocated budget.
- Possibility of integration with other engineering systems (ventilation, steam humidification).
- Exact coordination of all work with “subcontractors” (builders, designers, installers, etc.).
- Qualitative result. Designing will allow you to create an effective air conditioning system that best suits all the parameters and features of the room.
The bottom line is you get a system within your budget that works efficiently, is well located and works in conjunction with other engineering systems.
Availability of modes
This function is designed for the off-season, when there is no heating in the room, but it is cold outside.
In many split systems, outdoor units can operate at -7°C. At lower temperatures, the heating power drops and there is a risk of icing on the outdoor unit.
Some inverter models are able to heat the room even when it is -25 °C outside.
This mode makes it easier to endure the sweltering heat and prevents the spread of mold. This feature is now standard on most air conditioners.
This mode circulates the air in the room. As a rule, the compressor and fan of the outdoor unit of the split system are turned off, only the indoor one works. Do not confuse this mode with the influx of fresh air from the street.
Coarse filters are found in almost every air conditioner. They block dust and larger particles like fluff and wool. Filters must be removed and cleaned at least once every few months.
Much more important is the fine filter, which is able to capture the smallest pollen, various odors and cigarette smoke. Such filters cannot always be cleaned with a vacuum cleaner or rinsed with water. If necessary, filters should be changed immediately.
Consultants in stores can say a lot of flattering words about some newfangled filter, but they, of course, will keep silent about the need to replace it in a month or two.
For example, catechin filters can be used for about 30 days. After this period, they are not only useless, but also cause an unpleasant swamp smell.
This mode means the saturation of the air with air ions, which should provide a surge of strength, improve immunity and well-being in general.
This mode cannot be called marketing noodles, but many people do not feel any effect from ionization.
Air ions are air particles that carry an electric charge. Under natural conditions, air saturated with air ions is present on the slopes of high mountains, near waterfalls, on the banks of mountain rivers, seas and oceans.
This mode of operation can refer to completely different mechanisms.
- Special generator that uses the physical method of gas separation. It consists of two separators that absorb and remove nitrogen to the street, and return oxygen to the room.
- A special membrane that, when air is sucked in, retains nitrogen molecules, but allows oxygen to pass through.
- Air exchanger for supplying fresh air from the street and removing air from the room with a high concentration of carbon dioxide.
Simple household split systems cannot supply fresh air to the room. They only “drive” the air inside the room, cooling or heating it. The refrigerant, freon, circulates through the tubes between the blocks themselves.

Since manufacturers do not create special office options for air conditioners, split systems or ceiling-floor options are most often installed here. High-quality office air conditioning is possible only with the selection of the right equipment power.
Office air conditioning – a luxury or a necessity?
Why is it necessary to install air conditioning in the office? – In order not to be surprised at the gross decline in performance with the onset of another abnormally hot summer.
Practice shows that it is necessary to install an air conditioner in an office, and not only for the sake of prestige. Such equipment allows you to maintain an ideal microclimate in the room, regardless of what is happening outside the window, and therefore create an ideal environment for employees in which they can fully realize their potential and perform any work, giving their all one hundred percent.
The practice of many companies shows that installing air conditioning in the office means ensuring:
- No early departure from work due to headaches,
- Increased fatigue, and as a result, reduced performance,
- Minimum sick leave, because maintaining a suitable microclimate strengthens the human body.
Installing office climate control equipment will help ensure the normal productivity of employees, regardless of the temperature outside. An office air conditioner is not just a demonstration of the company’s status, it is a necessary equipment that provides normal conditions for its operation. The presence of such equipment can also have an economic effect, since it will allow employees to direct their efforts to solving the problems of the organization, and not to combat heat and stuffiness.
Installing an air conditioner in the office will prevent:
- employees leaving work early due to headaches;
- increased fatigue, which will affect labor productivity;
- private absence of employees due to illness.
The existing misconception that the presence of an air conditioner is the cause of frequent colds is caused by ignorance of the rules for operating climate devices. Another erroneous opinion is related to the high cost of such equipment. From a wide range of models on the market, you can choose inexpensive air conditioners, the price of which is affordable even for individual entrepreneurs. In addition, thanks to air conditioning, you can provide normal conditions for the work of the office team, even in a cramped office. And if you have an open office and customers visit it, then the lack of air conditioning can affect their loyalty to the company.
Requirements and regulations
Air conditioning and ventilation of offices is a rather complex task, its solution differs significantly from setting up an efficient system in a residential building. The main point is the intense heating of the air, especially during working hours, which is explained by the huge amount of productive computer equipment and numerous staff. For all their power, cooling units must also be quiet enough to allow employees to concentrate on their duties. If we talk about current standards, then the microclimatic conditions in the office must meet the following requirements:
- The air mixture must be 21 percent oxygen and a maximum of 3 percent carbon dioxide;
- Mineral and organic dust not allowed;
- The most comfortable temperature range varies from 20 to 24 degrees;
- Acceptable air humidity is in the range of 50-60 percent;
- The speed of movement of air flows from 0. 1 to 0.15 meters per second.
If calculations and installation are carried out by specialists, then strict adherence to these parameters is guaranteed. This allows not only to create the most pleasant working conditions, but also eliminates problems with controlling authorities.
How to choose an air conditioner for the office?
Be aware of the large number of people in the office throughout the working day, the presence of office equipment that produces heat. If you install an air conditioner in an office without considering these points, the effect will be minimal.
On average, the power of an air conditioner for an office is calculated from the proportion: 1 kilowatt per 10 square meters of a room.
With the above factors in mind, a multiplier of 25 to 40 percent is introduced.
For a small office space, a household appliance that can handle an area of up to 100 square meters is quite suitable. It can be a window version, mobile or split system with a power of no more than eight kilowatts.
If the office area is larger, you need to pay attention to the device from the semi-industrial series with a capacity of 8 – 15 kilowatts of cassette, channel types.
Less often, split systems are installed on large areas. Such air conditioners for the office will cope with the air in an area of up to four hundred square meters.
Air conditioning options
Office air conditioning with monoblock air conditioner
One of the most cost-effective office air conditioning options. A monoblock air conditioner is an indoor and outdoor unit combined into one housing and installed inside the office. To ensure heat removal, a corrugated pipe is used, which leads out of the office window.
The main advantages of this office air conditioning solution are the cost, simplicity of design, the ability to install an air conditioning system in any office and the ability to install the air conditioner yourself:
- You need to buy an air conditioner for the office in any chain store like Eldorado, m-video or online store
- Bringing an air conditioner to the office is usually not a big problem. most models can be brought by car in the cabin. It is worth paying attention that the air conditioner must be transferred in a vertical position – you should not transport the air conditioner for the office in a horizontal position. – Install the air conditioner near the office window (just install it on the floor, like installing a refrigerator)
- Connect the corrugated pipe that runs in the complex to the air conditioner (no tools are usually required, in rare models of office air conditioners a screwdriver is required)
- Connect corrugated pipe to office window. There may be a misunderstanding with this point – the vast majority of office air conditioners are adapted for the American market with windows rising up, and not with hinged windows like in Russia, so in most cases you just need to bring the corrugated pipe out of the office window and cover the sash, fixing it with a heavy subject.
- Then you need to bring a container (either a bucket or a large jar) and lower the drainage tube there.
- Plug in the air conditioner and enjoy air conditioning in your office.
The main disadvantages of this office air conditioning solution:
- these models are very noisy (to talk on the phone, the air conditioner will have to be turned off).
- designed for small office space (typically 14-25 m2)
- focus on the American market and the inconvenience of installing a corrugated pipe
- air conditioner takes place in the office near the window.
This office air conditioning solution is convenient due to its versatility – when the budget is limited and there is no way to install a split system (you can’t damage the facade, installation difficulties, etc., you don’t want to contact the installers – it’s dirty, you need to look for where to connect, you don’t want to decide question with the owner in a rented office) buying a monoblock air conditioner is an excellent way to air the office.
Office air conditioning with a non-inverter split system
The cheapest class of office split systems.
The main advantage is the cost of this office air conditioning solution.
The main disadvantages are the inability to start heating at temperatures below +5-0 degrees Celsius.
- slightly higher electricity consumption compared to inventory split systems for air conditioning offices.
- in very budget models of office air conditioners, the direction of flow adjustment may be absent.
Office air conditioning with inverter split systems
A fairly common type of office air conditioning. At a relatively affordable price, you can get full office cooling and comfortable air distribution.
Advantages of office split inverter air conditioning:
- , many models provide for the ability to adjust the flow direction both vertically and horizontally (when buying an air conditioner for an office, you need to look for just such a model – it costs not much more, but is much more comfortable. This solution allows you to deflect the flow horizontally (the air conditioner is located above the person , but blows away from him, and not on him) which increases the comfort of all employees in the office – a comfortable temperature is maintained in the room and no one is “blowing”.0012
- as a rule, these models of air conditioners for the office allow you to work on heating up to -10, -15 degrees, which allows you to feel comfortable in the off-season, quickly warming up the office in the morning, when the temperature outside can be about 0, and the heating has not yet been turned on.
- often has additional features like ionization, electrostatic filters, etc.
Office air conditioning with multi-split systems
This solution is a logical development of the previous one: several indoor units of air conditioners are connected to one external one, which allows not to clutter up the facade with a bunch of outdoor units. This solution is often used when the indoor unit is located at a distance from the outdoor unit. If for a conventional split system the restriction on the length of the route (one way) is 15-20 meters, then for multi-split systems it can reach 80-100 meters, which allows solving the problem of air conditioning remote offices, server rooms or meeting rooms located inside the building and without external walls. As a rule, up to 5-6 indoor units of office air conditioning can be connected to the outdoor unit of a multi-split system.
Office air conditioning vrv-system
This system is a large multi-split. The number of indoor units can reach 100 pcs, and the length of the route is 0.5 km. This air conditioning solution for offices is usually applied either in the complete reconstruction of the building or in the new construction of offices. The advantages of this solution are the ease of installation and operation of this system, and the disadvantages are its immutability (if you want to connect three new indoor units instead of one – for example, the office was re-planned and instead of one large room there were three small ones – this solution is impossible).
Air conditioning of offices using a chiller-fan coil system
This office air conditioning system is an extensive network of pipelines through which cold water flows (similar to a heating system, only instead of a boiler there is a chiller – a refrigeration machine, and instead of heating devices – fan coil units (internal blocks of air conditioners) with internal air conditioning units for offices – fan coil units and an external chiller unit (refrigeration machine – a source of cold).
The main advantages of this office air conditioning system: – The chiller-fan coil system is usually cheaper than the vrv office air conditioning system by 15-20% in terms of capital costs.
- this air-conditioning system for offices, with a competent design, allows you to connect the required number of indoor units at the required points, which is convenient when the office building is rented out in the shell and core stage without specific cutting of office blocks.
- this system has no limit on the length of the runs between the indoor and outdoor units.
- this air conditioning system has no capacity limitation (by installing chillers in parallel, any cooling capacity can be obtained in one system)
Cons of chiller-fan coil office air conditioning system:
- this system is harder to operate than vrv office air conditioning system.
- chiller-fan coil office air conditioning system is more expensive to operate than vrv office air conditioning system.
