How Does an Air-Conditioning Work?

  • A typical air-conditioner works by providing cool air inside your home by drawing warm air inside and removing its heat.

How Central Air Conditioners Work?

  • Every air conditioner contains a condenser with coils, an evaporator with coils and a compressor. The condenser and compressor are typically located together outdoors. The evaporator is more commonly located inside the house where it shares the same air handling unit (blower, etc.) used by the home’s forced-air furnace. It can however be placed outside the home with the condenser and compressor. Learn more

How to Choose the Right Home Air-Conditioner?

  • It is important to consider the size of your home for the right air-conditioner. An air-conditioner that is too large will compromise comfort as it needs to be turned on and off, while an air-conditioner that is too small could not keep up with load requirements in the hot summer months.
