The job of your residential air conditioning unit is to move heat from inside your residence to the outside, consequently cooling you and your home. The air conditioning unit blows cool air right into your home by drawing the warmth out of that air. The air is cooled by blowing it over a set of cool pipes called an evaporator coil. This works much like the cooling that happens when water vaporizes from your skin. The evaporator coil is full of a unique liquid called a refrigerant, which transforms from a fluid to a gas as it takes in warmth from the air.

The refrigerant is pumped outside your home to an additional coil where it quits its warmth as well as adjustment back right into a liquid. This outdoors coil is called the condenser because the refrigerant is condensing from a gas back to a fluid much like moisture on a cold window. A pump, called a compressor, is used to move the cooling agent in between both coils as well as to transform the pressure of the refrigerant to ensure that all the refrigerant condenses or vaporizes in the suitable coils.

The energy to carry out all of these is utilized by the motor that runs the compressor. The entire system will usually give about three times the air conditioning energy that the compressor utilizes. This odd reality takes place since the altering of the cooling agent from a fluid to gas as well as back once again allows the system to move more power than the compressor uses.


Routine upkeep and tune-ups for your unit such as altering filters can be handled by a lot of consumers, but others require specialist service.

It’s a great concept to clean dirt, as well as obstructions from the coils and the drains at the beginning of each cooling season.

Depending upon the system and the consumer, this may need a service call from a specialist.

If the system is not producing as much cold air as is regular, it could also be an indication of refrigerant or airflow problems. These issues might require repair service.
