Single-Phase and Three-Phase Split-System Central Air Conditioners and Heat Pumps

Energy Efficiency Regulations

Regulatory Definition

Air conditioner means a single-phase or three-phase central air conditioner that is a split-system and that has a cooling capacity of less than 19 kW (65,000 Btu/h).

Split-system heat pump means a single-phase or three-phase air-to-air heat pump that is a centrally ducted split-system and that has a cooling or heating capacity of less than 19 kW (65,000 Btu/h).

Energy Efficiency Standard
Air Conditioners (AC) and Heat pumps (HP) under 19 kW (65,000 Btu/h)
Product Minimum energy performance standard
AC other than small-duct and high-velocity – cooling SEER = 13
HP other than small-duct and high-velocity – cooling SEER = 14
HP other than small-duct and high-velocity – heating HSPF V = 7.1
AC & HP – small-duct and high-velocity – cooling SEER = 12
HP – small-duct and high-velocity – heating HSPF V = 6.3

SEER = Seasonal energy efficiency ratio – the total cooling of a central air conditioner or heat pump in Btu during its normal annual usage period for cooling, divided by the electric power usage in watt-hours during the same period

HSPF = Heating seasonal performance factor (Region V) – the total heating output of a heat pump during its normal annual usage period for heating, divided by the total electric power input in watt-hours during the same time period

Note: To compare U.S. energy efficiency levels with Canadian levels for heat pumps, HSPF V is equivalent to HSPF IV/1.15
