What Are Some Key Air Conditioning Terms I Should Know?

You don’t need to be an HVAC technician to learn about some of the key air conditioning terms to better help you understand how your AC cools your home. There are several different types of systems, including central air conditioners, packaged systems, and ductless air conditioners.

No matter what type of system you have installed in your home, air conditioners all function similarly.

1. Thermostat: The thermostat is what you use to let the AC unit know how cool you want to maintain your home. On ductless air conditioners, you can often use air conditioner remotes to change the thermostat.

2. SEER Rating: The SEER (Seasonal Energy Efficiency Ratio) rating is how efficient the AC is at keeping your home cool while providing energy efficiency.

3. MERV Rating: The MERV (Minimum Efficiency Reporting Value) refers to air filters and their efficiency to remove allergens, pet dander, dust, etc., from the air. The higher the MERV rating, the more efficient the filter.

4. AC Condenser: This is the part of the AC that removes heat from the home. If you place your hand on the AC unit, the condenser will be located on the part that feels hot.

5. Cooling Coils: These coils help create the cold air that blows out of your AC.

6. AHU (Air Handling Unit): The AHU consists of all the parts and components that make up the AC unit, including the fan, blower motor, cooling coils, condenser, and so on.
