Energy efficiency standard

Energy performance standard for split-system air conditioners and heat pumps under 19 kW (65,000 Btu/h)

Single Phase
Energy-using product Energy performance standard
Split-system central air conditioners, other than those that are space-constrained or small-duct and high-velocity SEER 2 ≥ 13.4

Off mode power consumption ≤ 30 W
Split-system central air conditioners that are small-duct and high-velocity SEER 2 ≥ 12.0

Off mode power consumption ≤ 30 W
Split-system central heat air conditioners, other than those that are space-constrained SEER 2 ≥ 11.7

Off mode power consumption ≤ 30 W
Split system central heat pumps, other than those that are small-duct and high-velocity or space-constrained SEER 2 ≥ 14.3

HSPF 2 (Region V) ≥ 6.0

Off mode power consumption ≤ 33 W
Split-system central heat pumps that are small-duct and high-velocity SEER 2 ≥ 12.0

HSPF 2(Region V) ≥ 4.9

Off mode power consumption ≤ 30 W
Split system central heat pumps that are space-constrained SEER 2 ≥ 11.9

HSPF 2(Region V) ≥ 5.0

Off mode power consumption ≤ 33 W

Three-Phase
Energy-using product Energy performance standard
Split-system central air conditioners, other than those that are small-duct and high-velocity SEER ≥ 13.0
Split-system central air conditioners that are small-duct and high-velocity SEER ≥ 12.0
Split system central heat pumps, other than those that are small-duct and high-velocity SEER ≥ 14.0

HSPF (Region V) ≥ 7.1
Split system central heat pumps that are small-duct and high-velocity SEER ≥ 12.0

HSPF (Region V) ≥ 6.3

Seasonal energy efficiency ratio (2) – 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 as determined in accordance with CAN/CSA-C656-14/10 C.F.R. Appendix M1

  • SEER = CAN/CSA-C656-14
  • SEER 2 = 10 C.F.R. Appendix M1

Heating seasonal performance factor (2) (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 as determined in accordance with CAN/CSA-C656-14/10 C.F.R. Appendix M1

  • HSPF = CAN/CSA-C656-14
  • HSPF 2 = 10 C.F.R. Appendix M1

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

Btu/h = British thermal units per hour
kW = kilowatts
W = watts
