Ensure that your room, whether at home or office, remains fresh all the time by getting the best window air conditioner, and this is only possible if you have the information needed to tell the good from the bad.

Factors To Consider Before Buying a Window Air Conditioner

The Size of Your Room

The Rooms’ sizes determine the power specification to consider in the A/C units. How much power is needed to cool my home/office adequately? This is the question that should come to your mind first.

Buy the right size A/C unit. Avoid buying a colossal unit than you don’t need or a tiny one that will not cool your room effectively.

For bedrooms, go for an A/C unit rates 80 watts / square M. For living areas, go for the units rated 125 watts/square M.

Noise Level

Avoid buying extremely noisy A/C units. Noisy A/C units are very annoying. They disturb sleeping children, lead you to shouting to be heard and at times disturb the neighbors. You may have to part with a little more bucks to buy a low noise A/C unit.

Energy Efficiency

With the gradually improving technology, finding energy efficient A/C units is now easy as pie. Ensure that you check the SEER rating of a given unit before purchase. The higher the SEER rating, the more efficient is the unit. An energy star logo and certification in a given conditioner is a guarantee of its energy efficiency.


Ensure that your preferred A/C unit is backed by a long manufacturer’s warranty. This way, you will always be safe in the case of quality or performance issues. Also, ensure that the warranty does not dictate the installation by specific contractors before doing it yourself.

Installation and Care

Ensure that your A/C unit is installed by experts or as per the warranty’s dictation. This way, you will be guaranteed of disappointment-free services. Also, maintain your A/C system regularly.
