Don’t Sweat It! Here’s How Your A/C Works To Keep You Cool
Are you curious to know how your air conditioner works to keep you cool? You’re in luck! We’ve put together a graphic to help you understand how it operates during the warmer Pacific Northwest months. You most likely have a central air conditioner in your home which is made up of the condensing unit which sits outdoors and indoor evaporator coils which are mounted on top of your furnace or air handler.
The Air Cooling Sequence
- When you set the temperature on your thermostat an electric signal is sent to your central cooling system thus beginning the cooling process. Pro-tip: Set your thermostat to 78º for maximum energy-efficient savings.
- The warm air is drawn in through your home’s air return vents then the air travels through a filter which removes dust particles or allergens.
- Through a closed system of tubes, the evaporator coils absorb heat from the air in your home using refrigerant. Refrigerant is a chemical that absorbs heat from the environment and transitions it from a low-pressure gas to a high-pressure liquid, and back again. The chemical produces a cooling effect while expanding or vaporizing.
- Once the heat has been absorbed the refrigerant travels through condenser tubes to the condensing unit where the heat is released outdoors.
- The chilled air then travels through the air ducts in your home which lowers the interior temperature. The cycle then continues to regulate according to your temperature adjustments.
