A window air conditioner also referred to a room air conditioner or window A/C is placed in a home window to cool a room or rooms depending on the size of the A/C. It's a viable alternative to central air that is piped throughout a house to cool every room.

a window air conditioner operates in different modes depending on the amount and typeA window air conditioner operates in different modes depending on the amount and type of cooling that is desired. Cooling mode lets room air cool and then sends that air back into the room. There are other models that will preset cooling and will cool a room until the unit is turned off. Others allow us to set a temperature, and the window air conditioner will run until the set temperature is reached then turn off until the temperature rises again. Many have fan modes that use less energy because no cooling is provided. The fan only mode is good to run on a cool day when we would like to circulate the air in the room. There ware also split air conditioning systems that have an outdoor unit as well as an indoor unit. The outdoor unit is placed near a wall outside the space that we wish to cool. The outdoor unit contains the condenser coil, compressor and expansion coil. The indoor unit is sleek and contains a blower, air filter and cooling coil. This system does require ductwork and is connected by tubing and wiring. If there is no handyman around, it's probably wise to consult with a carpenter or electrician to help install a split air conditioner.

One of the nice features of a window air conditioner is it cools the air and at the same time remove humidity. Depending on the model, the dehumidifying capabilities vary, and we should look for ratings measured in ounces and pints of moisture removed hourly. It' also convenient to buy a window air conditioner that has a remote control turn on and off and adjust settings. The remote control may also have a temperature sensor and a filter alert to let us know when the filter needs to be cleaned.

It's important that we know the exact size of the window air conditioner we are looking for because if it's too large, the room(s) will feel damp. If it's too small, the room(s) will remain at an uncomfortable temperature. To find the right air conditioner, we have to figure out the square footage of the room(s) we wish to cool. We also have to find the window air conditioner's British Thermal Unit (BTU) rating. That will tell us how much heat the conditioner can remove. In other words, if the room is 1,050 by 550 square feet, we will need at least a 12,000 BTU window air conditioner. It's also important to know the EER (Energy Efficiency Rating) because the higher it means a window air conditioner that is more efficient.

keeping in mind that window air conditioners can be quite noisy

Window air conditioners are generally made to fit windows that are double hung with a sash that can be lowered or raised. In order to find an air conditioner that will fit our window, we need to figure out the inside dimensions of the window. We must also realize that placing an air conditioner in a window that is shaded a good part of the day will help the conditioner to run at a more efficient level. Make sure that the window we are installing the conditioner in is close to a power outlet. The outlet has to be capable of handling the electricity lead the air conditioner will expand. We also need to make sure that the window air conditioner we choose is in concert with our electrical outlet. This can be done by checking the packaging for the design of the plug. If we have any doubts, we should consult an electrician.

Electronically Controlled Window Air Conditioners

The window air conditioner that offers electronic controls allows us to utilize a programmable timer to set it to run at specified times. This allows us to reduce our energy use by turning on the air only when we want it. We can adjust the cooling level and the speed of the fan with more flexibility which allows us to designate a temperature that the air conditioner will maintain. There is also a sleep setting that will increase a specific temperature in increments over an allotted time period, returning to the original temperature later on. This helps keep the room at a reasonable sleeping temperature and helps lessen the noise element since the conditioner runs less frequently.

Most electronically controlled window air conditioners also have an ionizer that helps remove pollen and other impurities from the air. The venting option lets us choose to recirculate the room air exhausting air from the room to the outside and pulling air into the room.

Testing Criteria

One way to choose a window air conditioner is the “if you can sleep near it, it's good”. In other words, it's quiet and doesn't make loud noises. It also offers the most control over air direction and climate control. In trying to find the perfect air conditioner, don't be discouraged. There are plenty of companies and organizations that put window air conditioners through rigorous testing procedures. Since most are focused on the more popular sizes of 8,000 to 10,000, for rooms between 300 and 500 square feet, the following information about testing is based on this. For window air conditioners this size the average price range is between $150 to %800. Most testers will track price, features, cooling capacity and specs. This group focused on what is standard and affordable and went with window units that were Energy Star qualified which included the Frigidaire FFRE083381, the GE AHM08LW and the LG LW8016ER. The main distinguishing factor was noise, keeping in mind that window air conditioners can be quite noisy. The Friedrich Chill, Haier Serenity Series and the Frigidaire scored high in this group. In the smart air conditioner category (those that work with smartphone applications) the GE AECO8LW and the LG LW8017ERSM came out test winners.

testers generally score window air conditioner models with 90% the best and 50% borderline

The testers focused mostly on noise because noise seems to be a primary factor in today's window air conditioners. In the bedroom, it can be particularly annoying and in the living room, the television has to be turned way up to overpower the AC. This seems to be due to the stricter standards for efficiency that have been set that have somehow affected the noise factor of some window air conditioners. However, there are models, as noted above, that are quieter, have a smoother frequency response and operate at a lower volume.

The testers developed a noise test by connecting a microphone to an iPhone and ran a noise peter application. Standing six feet away from each unit, the volume was measured at high, medium and low settings without running the compressor. Frequency spikes were noted as were irritating spikes in the frequency. The level and quality of user control were also judged. The noise was judged based on high cool and low cool settings using a sound meter.

Fan vents controlling the airflow direction were also tested. It was found that some models showed that blind spots prevented airflow from reaching certain desired areas. Fan speeds, cooling modes and remote-control depth including any Wi-Fi features were scrutinized. For example, comfort was judged by how rapidly an air conditioner set on low was able to cool a room at a set temperature.

Testers generally score window air conditioner models with 90% the best and 50% borderline. The heating and cooling scores tell us how much heating or cooling the air conditioner is delivering in comparison to the electricity used. The higher scoring models give more kWh of heating or cooling per kWh input energy, meaning they cost the least to run.

Air flow testing determines the amount of air the conditioner expels on its highest and lowest speeds with the lowest delivering a slight breeze and the highest a strong blast for heating or cooling rapidly. A window air conditioner with a high score has a variety of fan settings.

Different unit sizes of small, medium and large have individual scores to fit their size. For example, a large model can't equal the efficiency of a smaller model and the scores would be incorrect trying to compare the two.

Efficiency of Window Air Conditioners

A window air conditioner's efficiency is rated by SEER (Seasonal Energy Efficiency Ratio). The definition comes from the Air Conditioning, Heating and Refrigeration Institute (www.ahrinet.org). The rating is based on the cooling output of a unit during the cooling season divided by the entire electrical energy input during the season. If the SEER rating is high, the more energy efficient the unit is. In the United States, the SEER is determined by the ratio of BTU cooling to energy used in watt-hours. As an example, a 5000 BTU unit with a SEER of 10 BTU, running for 1000 hours at eight hours per day for 125 days would be a total cooling output of 5000 BTU x eight hours a day times 125 day is 5,000,000 BTU a year.

Figuring Annual Cost of Energy for a Window Air Conditioner

Electricity is most often measured by KW (kilowatts). Imagine an electrical load drawing 1.5 KW of power operating for eight hours using 12 kWh of energy for example. In the USA, we are charged on the total electric energy we use. Our electric bill gives us in kilowatt hours the amount of electricity used on a monthly basis as well as the price of electricity per kilowatt-hour.

Window air conditioning is referred to as tons of cooling meaning one ton is equal to 12,000 BTUs. One ton of cooling is equivalent to the amount of power needed to continuously be applied over 24 hours in order to melt a ton of ice. The yearly cost of electricity used by a 72,000 BTU conditioner, running for 1000 hours a year with a 10 SEER rating and an energy price of $0.12 per kWh is figured as: the unit size, BTU x hours each year, h x energy price, S/kW divided by SEER, BTU/Wh divided by 1000.

AHAM's Verification

there are window air conditioners verified by an AHAM's Verification program

There are window air conditioners verified by an AHAM's Verification program (ahamverifide.org) which means they have been verified a tested by an independent laboratory. This guarantees that the unit will run as stated by the product claims made by the manufacturer and include electrical energy in amps and cooling capacity (BTUs/hour). Window air conditioners that have an Energy Star verification guarantees that the conditioner meets the Energy Star criteria. AHAM is certified by the EPA and is approved to do verification testing for Energy Star. AHAM's mark has to be displayed on the window air conditioner's packaging and on any included literature.

What to Pay Attention to When Buying a Window Air Conditioner

When buying a window air conditioner, our first concern should be cooling capacity measured in BTU's (British Thermal Units) per hour. We should choose a unit with a BTU that is designed for the space we will be putting the conditioner in for the best efficiency. If the unit doesn't have enough BTU's, the cooling fan will run continuously, driving up our electricity bill. Likewise, a unit that is too large will not cool the room evenly leaving cold and hot pockets. Here's how to determine our cooling capacity:

If the room is 100 to 150 square feet, we need 5000 BTU's.
– 150 to 250 square feet – 6000 BTU's
– 250 to 300 square feet – 7000 BTU's
– 300 to 350 square feet – 8000 BTU's
– 350 to 400 square feet – 9000 BTU's
– 400 to 450 square feet – 10,000 BTU's
– 450 to 550 square feet – 12,000 BTU's
– 550to 700 square feet – 14,000 BTU's
– 700 to 1000 square feet – 18,000 BTU's
– 1000 to 1200 square feet – 21,000 BTU's
– 1200 to 1400 square feet – 23,000 BTU's

Also, factors like ceiling height should be considered. If the ceiling is above eight feet, we may want to up the BTU level. If the room is very sunny during daylight hours, we might want to increase the BTU's by 10%. If the room is often occupied by more than two people, we might add 500 BTU's for each additional person.

Our next consideration should be the installation of the window air conditioner. Since most units fit inside standard double-hung windows, we can follow the directions that come with the air conditioner. There are some models that can also be installed in a customized wall space with the accompanying hardware. This alternative comes in handy if our window dimensions don't fit the conditioner.

To Install in a Window

  • Window frame dimensions should be measured exactly, noting maximum and minimum width. Check dimensions on the window air conditioner's instructions. All conditioners come with installation kits that have side curtains to fill in extra space on the sides of the window.
  • To install on a wall, check the model to make sure it can be done and we have the right wall installation kit. Check the wall opening's width and note the dimensions of the product specifications. We may need to have a professional do the installation as wall installations are a bit more complicated than a window. Either way, when window or wall installation is completed, make sure the window air conditioner is level and the cooling system is facing inside and warm air exhaust outside.

Window air conditioners are powerful and we need to know that our electrical system is capable of meeting the unit's needs for electricity. Most operate on 220, 125 or 115-volt circuits Any air conditioner with a cooling capacity that is below 15,000 will fun on the usual residential circuits. Those with a capacity above 15,000 BTU's need 200-volt circuits and special wiring may need to be installed. Specifications will be listed in the unit's packaging as will the correct plug type.

Energy efficiency is best with an Energy Star rated window air conditioner. It uses around 10% less energy than other models. Most Energy Star units have digital thermostats, multiple cooling speeds and programmable timers. They also have rebates available for customers who purchase one. An Energy Efficiency ratio or EER gives us the number of BTU's the window air conditioner uses for every watt of power. In other words, the greater the EER, the better the air conditioner's efficiency. The United States Department of Energy recommends that we look for a window air conditioner that has an EER of 10l0 for cost saving and energy savings.

we should clean your window air conditioner at least twice a year

All window air conditioners need occasional maintenance to keep them running smoothly. Outside debris and dirt can accumulate on the back or inside the unit and particles and dust can build up on the air filter. These could greatly reduce the performance of our unit. We should clean our window air conditioner at least twice a year, once before using it and once at the end of the cooling season. Air filters can be rinsed and washed with soap and water. Refer to owner' manual for further instructions.

Leading Manufacturers of Window Air Conditioners

When we buy an air conditioner, we want to go with a name with know and trust. Here are a few manufacturers we can consider:

  • 1. Amana
  • 2. Frigidaire
  • 3. Haier
  • 4. Kenmore
The Amana 6,000 BTU Window Air Conditioner with Electronic Controls is perfect to efficiently cool a small room. It works best in a room that is less than 250 square feet. It is a snap to operate featuring remote and onboard controls with multiple operating modes. It sells for approximately $200.

A very reliable brand is the Frigidaire window air conditioner. It is one of the most popular window air conditioners purchased in the United States and has a low number of calls for service repairs. Frigidaire has many choices of portable and window air conditioners with models in sizes from 5000 BTU's up to 25,000 BUT's. The units are easy to install, affordable and quite small. They are one of the most energy-efficient air conditioners on the market. Some consumer favorite Frigidaire models include the FFRA0511R1 – 5000 TU, selling for around $150 and the FGRCO84451 8000 Smart Window, selling for approximately $300.

Running a close second is the Friedrich window air conditioner that is a popular bedroom brand because it is so quiet! If you’re looking for a quiet window ar conditioner to use in the bedroom. The Friedrich 5,800 BTU is a hardworking machine that happens to be one of the quietest on the market as well as one of the most energy efficient. Friedrich prices run between $300 to over $1000.

Haier offers affordable window air conditioners made in China in an extensive range of models that will cool rooms as good as some of the best US models. The units are pretty quiet, lightweight and somewhat energy efficient. A popular model is the Serenity Series 6000 BTU with Ultra Quiet Sound Package selling for $350.
Although Kenmore's air conditioners tend to be costlier than others, the feature they offer is outstanding including the Smart AC application which allows us to smartphone connect to the air conditioner wherever and whenever we want to turn it on, regulate the temperature, set speed fans, etc. A favorite model for many is the Kenmore Smart 12,000 BTU retails for approximately $500.

 

 

Buying Online Versus Retail

Why spend a day shopping store to store for a window air conditioner when we can simply go online and search for one? It's probably nice to see in “real time” what we are buying, but after running around looking at different models and different brands not only are we exhausted but have probably forgotten half of what we saw and learned. Not to mention the fact that it's quite unlikely that we can actually test the air conditioner in the store since most businesses are already running central air or are not equipped to plug a unit in to see how it runs.

Meanwhile, in the comfort of our home, we can check out what's available (trust us, there are hundreds), read reviews, check specifications, and decide which window air conditioner will serve us the best. Plus, we don't have to worry about lugging home an air conditioner that will probably take two people to carry it to the car and unload it. Ordering on the Internet means it will be shipped to us (often times with free shipping). Last but not least, online sites that offer window air conditioners often have incredible deals and sales we cannot pass up. Let's look at a few examples.

Sam's Club carries Frigidaire, LG, GE Haier and SEI. Prices range from $100 up to $750 and all models are shipped for free if we have a Plus Sam's Club membership. They give all models ratings, reviews and list all the specifications that go with the unit we are searching. For example, the GE Mechanical Room Air Conditioner is 115 volts, 5050 BTU,11.0 SEER (seasonal energy efficiency rating), with a mechanical thermostat, two cooling and two fan speeds. It includes an EZ installation kit and is ideal for a 100-150 square foot room. It sells for $109.00 (no sales tax) and is rated five stars with great reviews. Should we go to Walmart, the same unit sells for $126 including tax and pick up is free as well as two-day shipping. It makes perfect sense to buy this unit, online right?

Amazon has a great deal on the Frigidaire FFRE0633S1 6000 BTU Window Air Conditioner for $199.00 with free shipping. This unit is Energy Star rated and will cool down a room up to 250 square feet quickly. It comes with an auto restart function that when turning the unit on, reverts to its original settings. It also features an on/off timer and a clean filter (antibacterial) alarm. Customized settings are also available. Amazon also lists all specifications, ratings and reviews and has payment installment plans through their credit card.

Go to Overstock.com for the same Frigidaire's 6,000 BTU mini-compact window mounted on sale at $220. The low power start up is energy efficient, we'll save even more money in the long run. It received an Energy Star rating of 12.2 EER and uses a standard 115 V outlet. It also dehumidifies as much as 1.3 pints per hour and includes a clean air ionizer. Overstock will ship this item for free. offers online customer service for questions or more information on products.

this site offers window air conditioners that heat and cool in a wide range of choicesIf we are prone to allergies, Allergy&Air is the website to check out. This site offers window air conditioners that heat and cool in a wide range of choices in various sizes and power outputs. The Friedrich 7900 BTU 115V with a programmable timer and remote-control lists for $809 but is sale priced at $729 with free shipping. The website lists product specifications, reviews and has a question and answer page. Installment payments are available and there is a 30-day return policy.

This website list could go on forever, but we can easily see that shopping online for a window air conditioner is convenient and the only way to go. Going to various websites saves us money, time offers great values. Why waste our time, gas and the hassle of going from store to store to find an item that we can easily find online?

Fun and Interesting Figures, Data and Stats

  • We discovered that when air conditioner systems were discovered settings were measured in how many blocks of ice it takes to cool a room. This was referred to as “ice blocks“.
  • The main reason air conditioners were invented was for a New York publishing company having difficultythe air filter on a window air conditioner could be removed at least once a month controlling paper expansion and ink due to humidity. Willis Carrier was the inventor introducing AC in 1902.
  • Movie theaters were one of the first businesses to use air conditioning in their studios in the 1930s; thus, came the term “blockbuster“, which marketers used for their movie summertime hits.
  • According to the United States Department of Energy, we Americans spend over 22 billion and use 183 billion KW hours on air conditioning every single year!
  • Researchers have discovered that air conditioning does, in fact, save lives because the chances we will die on a hot day have declined by 80% over the past 50 years because of air conditioning.
  • If we purchased a window air conditioner during the 40's, we would have paid around $350. In today's terms, that would be approximately $3,500!
  • Packard was the first automobile offering air conditioning in 1939. It was very expensive and very large, hence, not so popular.

10 Tips for Window Air Conditioner Care

No matter where we live, short of Alaska, it can get pretty hot during the summer season, and window air conditioning can certainly run up summer electric bills. Here are some great ways to keep our window air conditioner running effectively and efficiently.
  1. The air filter on a window air conditioner could be removed at least once a month and cleaned with a mild soap, or white vinegar and water. If there are pets in the home or if we have allergies, clean the filter at least once a week. If there are holes, tears or damage to the filter, replace it.
  2. If the air conditioner was left outside and uncovered for the winter, before using it during the cooling season, check for bee or wasp nests. More importantly, always keep the air conditioner in a protected area when not in use or cover it with complete protection from animals and the elements.
  3. Window air conditioner coils should be cleaned at least once a season to remove dirt and dust from the the window air conditioner should only be used if the outdoor temperature is above 60 degreescondenser coils. This dirt inhibits the conditioner to work efficiently, causing it to run longer, driving up utility costs.
  4. Use warm soapy water to clean base of the air conditioner to prevent musty smell and mold. Do this the same time we clean the coils.
  5. Check the front coils of the window air conditioner for icing if the air outside the room where the conditioner is located is cooler than 60 degrees F. Icing on coils means the temperature is way too low for the unit to work properly. Ice buildup on coils means the temperature is too low for proper operation of the unit. The window air conditioner should only be used if the outdoor temperature is above 60 degrees.
  6. If our window air conditioner has a remote control, it could lose power due to a depleted battery. Check battery power often. If replacing batteries doesn't fix the problem, we may need to order a remote replacement.
  7. Don't leave our air conditioner in the window during cold seasons. It can cause chilly drafts and higher heating bills. Our air conditioner should be stored in a dry area like an attic or utility room. It should not be stored in a garage that is not heated. Any storage place should be free of bugs and rodents.
  8. To improve the efficiency of our window air conditioner, avoid installing in a window that has direct sun and uses a ceiling fan in the evening.
  9. Use a fin comb to straighten air conditioner fins. We can find them at any hardware or home improvement store.
  10. If we are looking to buy or replace our air conditioner, shop during mid or late summer for the best deals as retailers are looking to lessen their inventory.

Questions & Answers

Why is our window air conditioner making a noise?

Why is our window air conditioner making a noise?

If it's banging, there could be a broken or loose part. If it's buzzing, there could be dust or dirt trapped inside that needs to be cleaned out. It’s the last thing you want to hear when it’s 30-plus degrees Celsius outside and you’ve run out of ice cubes for your drinks. There’s some sort of weird sound coming from the air conditioner that you’ve never heard before. Any unusual sound warrants a phone call to a professional for diagnosis and repair.

How much should we use my air conditioner?

How much should we use my air conditioner?

We can use it as much as we like but keep in mind any window air conditioner takes energy and energy means a hike in our electric bill. Try setting a programmable thermostat to off when no one is at home.

Is our air conditioner too old?
