The ultimate guide to Air Conditioning 

How does an air conditioner work?

Central AC Explained In 8 Steps

  1. 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

  2. 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.

  3. Warm air is then drawn into your ductwork and cooled as it passes over the evaporator coil above your furnace

  4. This cooled air is then returned to the home through the return air vents

  5. Meanwhile refrigerant in your air conditioner absorbs the heat from the air as it flows through the evaporator coil

  6. This heated refrigerant is then pumped to the condenser or outside portion of your air conditioner.

  7. 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.

  8. This process continues until the desired set temperature is met.
