Factors To Consider When Looking For Window Air Conditioners

When looking for small window air conditioners, it is important to take a few things into serious considerations. Simply put, an air conditioner is designed to cool a room that does not have proper cooling. When shopping for the best window air conditioner, it is important to take the following factors into serious consideration.

1. Cooling Capacity

A window air conditioner's cooling capacity is one important factor to consider. Typically, a cooling capacity is measured in British Thermal Units (normally known as BTUs) on an hourly basis. For optimum efficiency, it is advisable to choose a unit that fits into the available space.

On the other hand, window air conditioners that have too little BTU will run for a long time trying to cool a large space and will end up consuming a lot of energy. If the cooling capacity is inadequate for a certain space, the air conditioner will leave the room prone to hot or cold air pockets.

2. Installation

Many window air conditioners are designed to comfortably fit in standard hung windows. However, there are certain models that are designed to fit into custom-created wall spaces using mounting hardware. It is therefore important for anyone looking for the best AC window unit to be truly cognizant of this fact.

When considering installations, it is crucial to look at the window measurements by paying special attention to the window's width. Having done that, it is important to read through the installation instructions and see the maximum dimensions. The best thing is the fact that all window air conditioners is the fact that they come with ready installation kits, which makes everything easy for the one installing.

3. Electrical Requirements

By design, window air conditioners are stronger than many household appliances, and therefore, it is advisable to ensure that the existing electrical system takes care of the unit. Typically, air conditioners operate on between 115 to 220-volt circuits.

The electrical requirements to take serious consideration of include voltage, watts, and amps. Normally, they are listed in the specifications part, and therefore, it won't be hard to know the right one.

4. Energy Efficiency

To manage the ever-rising electricity bills, it is important to look for a window air conditioner that is completely energy efficient. Generally, the best choice for a window air conditioner would be one that is economical and cheaper to operate.

Those that are energy start rated are known to produce 10% less energy when compared to those that are not. In that regard, it is advisable to go for the energy-rated models since they are energy efficient.

5. Maintenance

Window air conditioners need to be maintained every now and then so that they can maintain their tip-top condition. When in use, they are susceptible to getting destroyed by dirt and debris which accumulates at the back. On top of that, dust particles build up on their filter overtime which needs to be removed. It is in that regard very important to look for an air conditioner that is easily maintained.

For a window conditioner to have a long life, it should be cleaned thoroughly at least twice a year. This exercise is made easy if it has a slide-out chassis since all that one needs to do is slide it out for easy access. For many models, the air filter can be cleaned with soap and water.

Frequently Asked Questions About Window Air Conditioners

a) How Many Watts Does A Well Functioning Window Air Conditioner Use?

In normal circumstances, a small window conditioner will use between 500 watts to 800 watts on an average basis. On the other hand, larger and medium units consume between 900 to 1400 watts.

b) How Many Amps Does A Small Window AC Unit Consume?

Generally, small window air conditioners are designed to be energy efficient and, therefore, operate on the amperage range of between 15 and 20 amperes.

c) How Does One Clean A Small Window AC?

The next step involves cleaning the evaporator coils by vacuuming them and using a brush attachment. The same procedure should be followed for all the condenser coils that are situated at the back of the AC. If the coil is found to be bent during the cleaning process, it is important for it to be straightened using a fin comb.

d) Does A Small Air Conditioning Unit Come Accompanied By A Warranty?

Many brands have the usual 1-year warranty, which is good since it covers any manufacturing defects and service. However, there are some manufacturers who give buyers the allowance to buy extended warranties for an additional percentage of the initial cost.


As this article discusses, it is not hard buying the best smallest window air conditioner. All that the buyer needs to understand are the different features that it is supposed to have, how it works as well as the wattage. The best thing with many units in the market is the fact that they are designed to deliver exceptionally well and that they are fuel-efficient and therefore, the owner will not have crazy electricity bills.
