How does an air conditioner work?
Central AC Explained In 8 Steps
-
As the temperature in your house rises beyond what you set on your thermostat, a signal is automatically sent from your thermostat to the circuit board in your furnace
-
This tells the system that cold air is needed and turns on both the blower motor inside your house and the condenser, which sits outside your home.
-
Warm air is then drawn into your ductwork and cooled as it passes over the evaporator coil above your furnace
-
This cooled air is then returned to the home through the return air vents
-
Meanwhile refrigerant in your air conditioner absorbs the heat from the air as it flows through the evaporator coil
-
This heated refrigerant is then pumped to the condenser or outside portion of your air conditioner.
-
The condenser blows outside air across a different set of coils, which removes the heat from your home that was absorbed by the refrigerant, before the refrigerant is sent back into the home.
-
This process continues until the desired set temperature is met.
