Single-Phase and Three-Phase Single-Package Central Air Conditioners and Heat Pumps

Energy Efficiency Regulations

Regulatory Definition

Central air conditioner means a single-phase or three-phase central air conditioner that is a single package unit and that has a cooling capacity of less than 19 kW (65,000 Btu/h). It does not include a single package vertical air conditioner.

Single package heat pump means a single-phase or three-phase air-to-air heat pump that is a centrally ducted single package unit and has a cooling or heating capacity of less than 19 kW (65,000 Btu/h). It does not include a single package vertical heat pump.

Compliance Date

January 23, 2010 for through-the-wall central air conditioners or heat pumps

January 1, 2017 for all others central air conditioners or heat pumps

List of Compliant Models

Single package central air conditioners

Single package central heat pumps

Test Standard

CSA C656-05 for through-the-wall central air conditioner or heat pump

CAN/CSA-C656-14 for all others central air conditioners or heat pumps

Energy Efficiency Standard
Air Conditioners (AC) and Heat pumps (HP) under 19 kW (65,000Btu/h)
Product Minimum energy performance standard
AC & HP other than through-the-wall or small-duct and high-velocity – cooling SEER = 14
HP other than through-the-wall or small-duct and high-velocity – heating HSPF V = 7
AC & HP – through-the-wall – cooling SEER = 12
HP – through-the-wall – heating HSPF V = 6.4
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 for heat pump with Canadian levels, HSPF V is equivalent to HSPF IV/1.15

Energy Efficiency Report Requirements
