- ARI
- The Air-Conditioning and Refrigeration Institute.
- ASHRAE
- American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Inc.
- Btu
- British Thermal Unit
- Capacity (Cooling)
- The quantity of heat in Btu which an air conditioner or heat pump is capable of removing from an enclosed space in one hour, expressed as thousands of Btu/hr or MBtuh.
- Energy-Efficiency Ratio (EER)
- The ratio of the cooling capacity in Btu to the electric input to the air conditioner or heat pump in watt-hours.
- Heating Seasonal Performance Factor (HSPF)
- The total heating output of a central air conditioning heat pump, in Btu, during its normal usage period for heating, divided by the total electric energy input in watt-hours during the same period.
- Phase
- Phase of electrical service - single-phase or three-phase
- Seasonal Energy-Efficiency Ratio (SEER)
- The ratio of the total cooling capacity in Btu during a normal annual usage period to the total electric input in watt-hours to the air conditioner or heat pump during the same period.
- Single-Package System
- An air conditioner or heat pump with all major components housed in a single casing.
- Split System
- An air conditioner or heat pump consisting of two or more major components which are not enclosed in one cabinet. For a split system, a compressor and condenser are generally installed outside the building and the cooling coil is generally installed within the building.
- Ton
- (Heating or cooling) 12,000 Btuh.
