With a window air conditioner, you can keep one room of your house cool throughout the summer months.. Window air conditioners are an option if you don’t use air conditioning much or don’t have central air in your home. Window air conditioners are available in a variety of sizes, each corresponding to a different room’s temperature control needs. A large range of options is available, resulting in a variety of prices for purchase and installation.

Between $350 and $1,150, the national average cost of window air conditioning installation is $546 for a 340-square-foot 8,000 BTU window air conditioner. To get a 5,000 BTU window air conditioner installed for 150 square feet, you can expect to pay about $277.

Window AC Installation Cost

Window Air Conditioner Calculator

The cost of installing window air conditioning varies based on the type and size of the space to be cooled and the type of unit to be used for that purpose. Traditional window heat pumps are the most affordable window air conditioners, but energy-efficient and smart air conditioners are more expensive. Larger rooms, rooms that receive a lot of direct sunshine, and rooms located on the second floor of a house will all require AC systems with greater British thermal unit (BTU) ratings, which will raise their cooling costs. In our window AC calculator, we’ve taken these distinctions into account, as well as regional variances in costs. Depending on where you live, this window air conditioner cost estimator can help you determine how much you can expect to pay for a unit.

Window Air Conditioner Price by Size

According to its size, a window air conditioner can cost anywhere from $60 to $700. For example, a window air conditioner can only chill a certain amount of space. British Thermal Units (BTUs) are units of energy used to raise the temperature of one pound of water by one degree Fahrenheit. BTUs are used to measure the size of both heating systems and air conditioners. When choosing a heating system, keep in mind the size of the room as well as the local weather. Consider the size of the cooling area and the ambient heat factor while using window air conditioners. The more BTUs you need, the larger the area you are trying to cool.

It’s easier to cool a bedroom with a lot of shade and just one person than a kitchen the same size with numerous appliances and everyone in the family uses. As a result, to appropriately determine the amount of BTUs required to cool a room, begin by determining the size and suggested BTUs of the area and then add 10% to each of the following: rooms on the second story and rooms that receive direct sunlight throughout the day. Additional 600 BTUs should be added for each additional person in the room that uses it. As a last point, kitchens require about 4,000 more BTUs than other areas. As an example, a sunny kitchen with four inhabitants requires around 7,000 more BTUs than a bedroom.

The BTUs per square foot and the average unit cost for that size are shown in the accompanying chart.. Recall that you want to be inside a certain percentage of the target figure. Going over rather than under is preferable. You should not exceed your calculated figure by more than 20%, since this will result in a larger, more expensive, and more frequently turned on and off device that will also wear out faster. It is impossible to properly chill the space with a unit that is more than 10% smaller than the value you calculated. Recall that window units are designed to cool only the room in which they are installed. There is no way to chill numerous rooms with a single unit.

Window AC Price by Ton

Window air conditioners can cost anywhere from $60 to $1,000, depending on their cooling capability, which is measured in BTUs or tons. 12,000 BTUs of heat may be removed every hour by a single ton. More often than not, the weight of a unit is less than 1.5 tons. The amount of area you have to work with is a major factor in determining the size you need. A 0.5 to 1 ton window unit is sufficient for a 150 to 500 square foot space. A 1.5-ton unit is needed for spaces of more than 1,000 square feet. Based on tonnage and BTUs, the chart below shows how much a window AC unit will cost.

Window AC Unit Cost by Type

Window air conditioners can cost anywhere from $250 to $800 on average, depending on the model. Smart Air, Energy Star Rated, and Window Heat Pumps are the three primary types of window air conditioners. Each style has its own advantages and disadvantages, as well as its own price.

An opportunity to receive a discount may exist. One of the biggest drawbacks of this model is that it is more expensive than other options. An energy star window AC unit typically costs $300 to $700.

Window AC Heat Pump

If you want the option to heat or cool a room in your home from one unit, get a window heat pump. Heat or cold from the outside world is brought inside by these devices. These units provide many benefits, including that they are quieter than traditional air conditioning units. One unit provides heating and cooling needs, and there is no need to remove the unit at the end of the season. Some cons of window AC heat pump units are they may require a special outlet that can increase installation costs, are not as efficient at heating the room as it is at cooling it and are more expensive than a standard window AC unit. Between $500 and $800 is the usual price for a window AC heat pump unit.

Window AC Price by Brand

Window heat pumps let you heat or cool an entire room in your house with only one device. When the temperature outside drops, these units draw heat or cold from the air and bring it inside. These machines have a number of advantages, including the fact that they are quieter than conventional air conditioners. Heating and cooling are provided by a single unit, which does not need to be removed at the end of the season. While window AC heat pump units have their advantages, they also have some disadvantages, including the need for an additional outlet, less effective heating and cooling capabilities, and higher prices than a typical window air-conditioning unit. An AC heat pump for a window typically costs between $500 and $800.

Hitachi Window AC Price

Between $150 to $650 is the range for the price of a Hitachi central air conditioner. The air conditioners made by Hitachi are efficient and cost-effective.

You should anticipate to pay between $50 and $150 for the installation of an 8,000 BTU window air conditioner for 340 square feet and $200 to $1,000 for the materials.

Window air conditioners can be installed by the homeowner in a variety of configurations. The units come with installation kits that make the process a breeze. A professional installation, on the other hand, makes the window and air conditioning unit more secure. Handyman, HVAC technician, or even the business where you bought the unit can install it for you. The item is often installed in an open window. The kit is linked to each side of the unit, and slides outward to the window sill, allowing for easy access. It can be either nailed in or simply tightened by extending the sides of the piece once it has been installed. Then, the window is lowered down onto the top of the unit to secure it.

In most cases, window air conditioners are installed for a short period of time. To begin the season, they are installed and taken down as soon as the weather turns chilly once more. Some situations need the use of permanent installations. A small portion of the window is only accessed by low-profile devices, which hang below the window and do not obstruct natural light. A permanent installation is required for these devices. Using a ready-made kit to keep the unit in place is faster and less expensive, but this method of installation takes longer and costs more money. Between $50 and $75 is the cost of a kit for temporary installations. $100 to $150 is the average price to install a permanent installation for a single unit or vertical unit.

How Much Does it Cost to Run a Window Air Conditioner?

Running a window air conditioner can cost anywhere from $41 to $103, depending on the unit’s size, SEER rating, and the cost of electricity in your area. These are just a few factors to consider. The amount of AMPs your device consumes is determined by the size and efficiency of the device. You also need to know the power consumption of the appliance. Larger devices require a 240-volt outlet, which reduces their output when using a 120-volt socket.

Your wattage usage can be calculated by multiplying your AMPs by your watts. After that, divide it by 1,000 to get the kilowatts-per-hour use of your air conditioner. (Amps x Watts) / (kWh) = Kilowatts per hour (kWh) (1,000). Next, find out what your local electricity rate is. Your electric statement will have this itemized. Cost per hour is calculated by multiplying the cost by the kilowatt-hour (kWh) use of your air conditioner. The costs of running a window air conditioner in the summer are shown in the table below. Depending on your SEER rating, the cost of power in your area, and how many hours and days a year you use the unit, your costs could be significantly higher or lower.

5 Best Window Air Conditioners 2022 - Top Small Window AC Units to Buy

Window AC Maintenance

Most window units require only an annual or biannual $100 to $150 of maintenance, making them relatively low-maintenance. To keep the warranty intact, the service must be conducted by a licensed AC firm. Maintenance visits are conducted by HVAC technicians, who do checks on the unit as well as filter cleaning and drain cleaning. In order to ensure that the cooling system is functioning properly, the technician checks the coolant levels. The AC unit of a homeowner can be maintained by following a few simple guidelines. Keeping an eye on the filter and removing any overgrowth or brush from the base of the external unit are two simple ways to keep your air conditioner in top shape. Filters should be replaced every three months.

Portable AC vs Window AC

A single-room air conditioners don’t have to be limited to window units. You can also use a handheld device. Window air conditioners, which range in price from $350 to $1,150, are less expensive than portable models. They are smaller and less prone to get in the way, so they can be left in the window all year round. Removing and reinstalling some items on a seasonal basis can make them more difficult to utilize. Windows come in a variety of sizes and styles, making them an excellent choice for cooling a room. When compared to portable devices, they do not take up floor space, eliminate clutter, are smaller, and are easier to store when not in use Most window air conditioners are visible from the outside and must be installed or removed if they are not meant for year-round use. They can be damaged by falling from the window if they are placed incorrectly.

A portable air conditioner can cost anything from $300 to $1,500. These devices are the most convenient of the two because they don’t need to be installed. They are often wheeled and may be moved about easily. If you live in an apartment or condo, a portable air conditioner is a great option. Because of the wide range of sizes available, these air conditioners may be used to cool a variety of rooms. Portable units have their advantages and disadvantages. There is a lot of floor space needed for portable units, and they take up a lot of storage space when they are not in use. These units are cumbersome to carry and store because of their weight and size. They can’t chill a room as effectively as window units can.

Window AC vs Wall AC

A wall-mounted AC unit is another choice for a room air conditioner. These are similar to window units in many aspects, but they are installed into the wall instead of the window. There is no need to remove a wall AC unit even if it is not being used, unlike a window unit, which must be removed and reinstalled each time it is turned off. There are a variety of sizes and styles to choose from; they don’t take up any floor space; and they are really effective at cooling a place. Both wall-mounted and window-mounted air conditioners cost about the same to buy. Installing a wall AC unit is more complicated and hence a little more expensive, as it requires cutting an aperture in the wall and fastening the unit, as well as caulking around the opening. Between $350 to $1,150, a window AC unit can be installed, while a wall AC unit can cost up to $9,000.

Window Unit vs Central Air Cost

Installing a central air conditioner may be a good idea if you live in a hot climate throughout the year. It’s possible to cool the entire house with a single central air conditioning unit. However, if you simply need to chill or heat a few rooms, a window unit may be a better option. The area around the window that the window AC cools is limited. A single unit cannot be used to chill many rooms in a big, open area. Multiple units are required to chill a large area. Most window units, on the other hand, aren’t designed to remain in the window all year long. This means that you will have to spend money to remove and replace them on a regular basis. Between $350 and $1,150, you may expect to pay for a window air conditioner. Costs for central air conditioning range from $5,000 to $12,000.

Window AC Repair Cost

Repairing a window air conditioner typically costs between $50 and $125. From simple to complex and inexpensive to pricey, repairs can be found. You want to figure out if it’s more cost-effective to repair or replace a piece of equipment. Window air conditioner repairs include thermostat failure, charging the unit, repairing damaged parts, and cleaning the unit if dirt is freezing it. It may be more cost effective to replace a window air conditioning unit if the equipment develops many problems or the motor fails. The repair cost may be worth it if you get a high-efficiency unit with a higher BTU capacity.

Window AC Recharge Cost

It costs between $125 and $300 to get your window unit refilled by a professional. It’s time to replace your air conditioner’s refrigerants if it’s not producing chilly air. Recharging the device is the term for this. When a leak has been repaired and the refrigerant levels are low, it is common practice to perform a recharge. Recharging a battery is rarely necessary if the device is working properly. Freon recharges are a sign that something is wrong with the unit and may necessitate a new one. A refrigerant kit and the associated equipment may be purchased for less than $100 to recharge most window units.

Enhancement and Improvement Costs

Window AC Thermostat

Make any adjustments to your heating or cooling system, and you’ll need a new thermostat. Thermostats control the temperature in your home and regulate when your furnace or air conditioner is activated and deactivated. Consumers can choose from an array of programmable and non-programmable models with or without Wi-Fi or other smart features that are now available on the market. In most cases, the price of installing a new thermostat is in the range of $150 to $400.

Window AC Accessories

In most cases, a complete set of installation tools is included with your window air conditioner. A cover ($25-$60), skirt ($25-$75), insulation ($10-$25), side panels ($20-$30), and brackets ($100-$150) are a few of the available add-ons. If you need to replace any of these accessories, you can do so on your own. With the right accessories, an air conditioner can run at its peak efficiency.

Outlet Installation Cost

If you don’t have an outlet nearby, you’ll need to pay between $120 and $200 to have one installed. In order to operate some air conditioners, you’ll need a 240-volt outlet. Electrical outlets come in several shapes and sizes, some of which are necessary for certain home appliances. Appliance malfunction or even a fire could occur if the improper type is utilized. If you don’t know what you’re doing, it’s best to leave the installation of an electrical outlet to a professional electrician.

Additional Considerations and Costs

  • DIY. The vast majority of window units can be installed by the user. Simply lift the window and remove the screen, place the unit on the sill, and extend the side kit to fit snugly. As you tighten the sides of the window, lower the window to keep it in place.
  • Estimates. Obtain at least three quotes from each HVAC contractor you’re considering. Using this information, you may make an educated decision on who should execute the task and at what cost.
  • Types of windows. All windows aren’t created equal. For instance, some are made for casement windows and are too tall for double-hung, while others may be sill-style devices that require a certain mounting. Before making a purchase, be sure to research the suggested window type for the item in question.
  • Shades or blinds. Installing a blind or shade that lowers but does not block the air conditioning unit, rather than curtains or drapes, can provide you with the privacy you desire for your window.
  • Regulations. If you reside in a condo, apartment, or a tight HOA, you may be limited in the types of units you can utilize. Before making a purchase, always check with your management or HOA board.
  • Replacement. In most circumstances, the cost of replacing an old unit with a new one of the same size is the same. The price varies slightly according to the unit’s size and design. The size of the project will grow if, for example, a smaller temporary unit is replaced with a larger permanent unit. In contrast, installing a new unit of the same size and type incurs the same expenditures as replacing an existing one.
  • Requirements in terms of electricity. It is the contractor’s obligation to inform the homeowner of any necessary upgrades to the electrical circuits or the building structures. When the house is first being inspected, make sure to perform this step.
  • Enclosure for a window air conditioner. If you have an AC unit in the middle of your yard, patio, or other outside area, it might be an eyesore. Adding curb appeal to your home may be done in a matter of minutes with an enclosure unit. A fence, screen, or even latticework can be used to conceal an air conditioner, which is a typical practice among homeowners. In order for an air conditioner to work properly, it must be exposed to the outside environment.

How Do Window Air Conditioners Work?

A lack of coziness this summer may be to blame. Are you curious about how a window air conditioner works, if so? Do you think a window unit would be a good fit in your house? Take a look at how window air conditioners work and see if you can benefit from them this year.

What is a window air conditioner?

The most basic sort of AC unit is a window unit. Each component and portion of the system is enclosed within a single box or casing. Traditional electrical outlets can be used to power this type of air conditioner. Convenience is provided by the fact that it may be moved from one window to another as needed and that it runs independently of the home’s HVAC system.

How does a window unit work?

Any air conditioning system, including a window AC, operates on the same basic principles. Cooling air is circulated into the room when heat and humidity are removed through the use of refrigeration. An evaporator coil and condenser coil are two of the most important parts of an air conditioning system.

The AC unit’s thermostat activates the blower motor as the room temperature rises. The cold refrigerant coils are cooled by the room air that enters the unit. Aeration lowers the room’s temperature by forcing cooled air via chilly coils and out the door.

How do you pick the right window AC unit for your home?

Size is the most important factor to consider when purchasing a window air conditioner. In order to keep the room cool, you’ll need a unit that’s a little on the tiny side, which means that it will have to work harder than necessary. Because of its size, it will chill the area too quickly without eliminating the humidity effectively, resulting in a cool environment that still feels squishy.

Analyze the room’s square footage before making a final decision on a window air conditioner. One square foot of space requires about 20 British Thermal Units of cooling capability from a window air conditioner. In order to figure out how big a room is, simply multiply the length by the breadth. Those BTUs should be plenty to cool the area. Be careful when you choose what window to put the unit in. Also, things like the size of the window, the position of the window in the room, and the weather outside can have an effect on how effective this method is. Consider the potential influence of the weather.

How to Clean a Window Air Conditioner

  • A window unit’s square footage should be taken into consideration. According to the British Thermal Unit (BTU), a unit of cooling capacity, one square foot of space requires 20 BTUs (British Thermal Units). Multiply room dimensions by 20 to get the total length and width. BTUs should be sufficient to chill the room. When deciding where to place the unit, take care. Further influencing its efficiency are variables like as window size and position and weather conditions. Examine the potential influence of the weather.

What You’ll Need

Equipment / Tools

  • Brush attachment for shop vacuum
  • Fin comb or knife with a slender blade
  • Cloth for cleaning
  • A cannister of spray
  • Compressed air in a can (optional)
  • A pair of gloves to keep you safe
  • Screwdriver


  • 3 percent hydrogen peroxide in a bottle
  • Coil cleaner for AC (optional)



Remove and Clean the Face Panel

The front of your air conditioner has a grate made of plastic or metal called a face panel (or grille cover). Screws, clips, or tabs can be used to attach it to your computer. Remove it by following the directions in your user manual. It’s possible that the filter may be incorporated into the face panel of some models. To remove the filter, follow the manufacturer’s instructions.

To clean the face panel, spray it with preferred cleaning solution and wipe it down with a cloth after the filter has been removed. Take it outdoors and use a garden hose to clean it up. While you’re cleaning the rest of the device, remove the face panel and let it air dry.

Remove and Clean the Filter

Remove the filter by following the directions in the owner’s manual that came with your air conditioner. Others have the filter placed behind the face panel, while others have it integrated in the face panel itself. Once the heavy sediment deposits have been removed, use a vacuum to remove any remaining dust and dirt, and then wipe it down with a wet cloth to clean it.

Take it outside and give it a good soaking with a hose for a more thorough cleaning. When flipping it halfway through, it should take a couple of hours for the filter to dry completely.

Vacuum out the Interior

Clean the inside of your air conditioner with a vacuum cleaner. The evaporator and condenser are located on the front and back, respectively, with the drain pan on the bottom and the fan and blower in the middle.

Clean the condenser and evaporator’s aluminum fins with extra care. Vacuum in the same direction as the fins (vertically or up-and-down) if at all possible to avoid hurting or bending them.


When handling aluminum fins on the compressor and evaporator, it’s a good idea to wear gloves.

Spray it Down

Use hydrogen peroxide to disinfect the cabinet’s interior and external surfaces, then wipe clean the surfaces you can reach with a cloth or rag.

The evaporator and condenser coils can be cleaned using the same spray cleaning solution, or an AC coil cleaner spray cleaner can be used. You have the option of letting the cleaner air dry or running water over it to remove it. Rinse it off if you’d like, but let the cleaner sit for at least 10 to 20 minutes to release any stubborn residue.


Compressed air can be used to clean the condenser and evaporator coils before spraying down the fins with a can of water. This will get rid of any debris that the vacuum missed and give your house a thorough cleaning.

Straighten the Fins

Air conditioner performance might be hampered by bent fins on the evaporator or condenser. Insert a knife or fin comb into the gap between the fins, just above or below the bent sections. Straighten the bent fins by running a knife or comb in the same direction (parallel) as the surrounding, unaffected ones.
