 Small window air conditioner units buying guide

So, what should you consider when choosing the best & smallest window air conditioner?

1. The air conditioning unit BTU

The BTU (British Thermal Units) is a basic measure of thermal energy and determines the capacity of your small window air conditioner unit. The more the BTU, the bigger the AC unit size and weight.

2. Your room size vs the AC unit BTU

Calculate the room size in square feet. Multiply the length and width to get the square footage. To determine the BTUs needed to optimally cool your room.  The following table is a guide  on the room size vs the  BTUs. Also consider the other factors listed below the table to objectively determine the BTU requirement.

Area To Be Cooled (Sq. Ft.) Capacity Needed (BTUs Per Hour)
100 to 150 sq. ft. 5,000 BTUs
150 to 250 sq. ft. 6,000 BTUs
250 to 300 sq. ft. 7,000 BTUs
300 to 350 sq. ft. 8,000 BTUs
350 to 400 sq. ft. 9,000 BTUs
400 to 450 sq. ft. 10,000 BTUs
450 to 550 sq. ft. 12,000 BTUs
550 to 700 sq. ft. 14,000 BTUs
700 to 1,000 sq. ft. 18,000 BTUs
1,000 to 1,200 sq. ft. 21,000 BTUs
1,200 to 1,400 sq. ft. 23,000 BTUs

 

Apart from the room square footage, adjust the BTU capacity  of your small window air conditioning unit as under;

  • Increase the BTU if the ceiling height is more than the normal 8 feet
  • Are you more than 2 people in the room? For every additional person, increase by 600 BTUs.
  • Is the window AC unit being installed in the kitchen, increase by 4000 BTUs.
  • If your room enjoys more sunlight, increase the BTU by 10%

3. The environment the AC will operate in

Some of the factors to take into consideration include the amount of sunlight and thus heat your room  receives. This will be determined by the number of windows and the direction they face.

North facing windows are in shade whereas western facing windows receive most sunlight.

Whether your room exterior has a shade or not also determines the amount of heat received. Keeping the exterior of the room you are cooling shaded will help the small window air conditioner  unit to keep you cool. However,  make sure that airflow around the exterior of the unit is not restricted by trees, shrubs or other obstructions.

4. Your electrical power specifications

Know your specifications and ensure that your choice small window AC unit plug is compatible with your outlet. Also confirm that the circuit can handle the additional power requirement to prevent circuit breaks.

5. The Energy Efficiency

Be on the look-out for energy star rating and /or energy efficiency ratio of your best & smallest window air conditioner on the market. The higher the EER, the more efficient the Window AC unit. The Air Con units with an energy star rating may use 10% less energy.

6. Filter

Ensure that the small window air conditioner unit filter can easily be accessed, removed, cleaned and reassembled.

7. Window location

You are likely to get a better performance if your window is centrally located on the wall.

8. Noise

Some are relatively quiet, others are loud especially when set on high. Depending on whether you are a light sleeper, the noise may be a lullaby or a distraction.  A noisy small window AC unit may also be a distraction in an office.

9. Warranty

How long is the warranty of the small window air conditioner unit? The longer the warranty, the better.

10. Additional features

Be on the look-out for these features that improve efficiency or make it more convenient to operate your Best & smallest window air conditioner on the market.

  • What is the dehumidification capability per hour?
  • Timers that allow you to set the time the small window AC unit can be operation e.g. just before you get home to when you are asleep
  • Easy to use controls that may be mechanical or electronic. Electronic controls allow more flexibility.
  • Does the small window air conditioning  unit have a remote control that allows you to control settings from anywhere in the room?
  • A sleep mode where the AC unit increases the temperature gradually as the room occupant is sleeping. This subsequently reducing pressure on the compressor and the noise in the room.
  • Be on the look-out for a filter alert that signals the need for cleaning.
  • Does the window AC unit have an electronic ionizer assist the AC to more efficiently remove impurities from the air?
  • What are the venting options? Is it to recirculate room air, pull in air from outside or exhaust room air outside?
