Any time you need to have your A/C system repaired or replaced, it is helpful to understand the air conditioner terminology used within the industry. So, the experts at AirRite have put together this handy glossary of air conditioner terminology for our customers.
- ACCA – Air Conditioning Contractors of America. The national trade association for A/C professionals.
- Air handler – The indoor half of a split system.
- Coil – An array of metal tubes or fins through which air is blown. There are two coils in any A/C system: an evaporator coil within the air handler, and a condenser coil outdoors.
- Compressor – The refrigerant pump located inside the condenser unit.
- Condenser unit – The outdoor half of a split system.
- Cooling load – The amount of cooling power needed for a specific home.
- Ductless mini split – A split system that has a single condenser unit connected to more than one air handler. Having multiple air handlers removes the need for a duct system.
- Expansion valve – A valve within the air handler that regulates refrigerant pressure.
- NATE – North American Technician Excellence. The professional testing and certification program for A/C technicians.
- Refrigerant – The pressurized chemical that flows through an A/C system and absorbs heat from the indoor air. Refrigerant types are often noted by the letter “R” and a designating number, like “R-22″ or “R-410A.”
- Safety cap – A locking device that covers the refrigerant valves on an A/C and prevents refrigerant huffing.
- SEER – Seasonal Energy Efficiency Ratio. It rates how much cooling is produced per watt of electricity used, on average, by an A/C unit.
- Split system – An air conditioner that is split between an indoor unit (which cools the air) and an outdoor unit (which gets rid of the heat from indoors).
- Ton – The common unit of measurement used to describe the cooling power of an A/C system. Its name comes from the fact that it originally referred to the cool air provided by 2,000 pounds of ice.
