Canada's Energy Efficiency Regulations

Higher Efficiency Requirements for Package Terminal Air Conditioners and Heat Pumps
Bulletin on Amending the Standard
July 2010

The Office of Energy Efficiency (OEE) of Natural Resources Canada (NRCan) is proposing to amend Canada's Energy Efficiency Regulations (the Regulations) under which dealers in Canada would be required to comply with higher efficiency requirements for package terminal air conditioners and heat pumps (PTAC/HP).

The purpose of this document is to provide stakeholders with background information for meaningful consultation on the content of the new regulation before proceeding with pre-publication in the Canada Gazette. This bulletin attempts to address key issues that may be raised. It is not intended to provide a definitive representation of the proposed regulation.


In Canada, the Energy Efficiency Regulations for PTAC/HP were last revised in 2004. Recently the minimum efficiency levels in ASHRAE 90.1 have been increased and incorporated into US regulations for 2012. The proposed efficiency requirements in this bulletin will harmonize the requirements in Canada with those in the United States.

Product description

PTAC/HP are factory manufactured air conditioners and heat pumps that have wall sleeve and separate un-encased combination of heating and cooling assemblies intended for mounting through the wall. Former terminology used to describe where the equipment can be installed has been changed from "replacement" and "new construction" to "non-standard" and "standard" respectively.

A packaged terminal heat pump has a similar configuration as a packaged terminal air-conditioner but includes a reversing valve to provide reverse cycle heating.

A majority of this equipment is found in motel and hotel rooms, providing heating and cooling to a single room. PTAC/HP are also used in condominiums and long term health care facilities.

Minimum Performance levels

Standard size (new construction) Minimum efficiency requirements
Equipment Cooling Capacity (Btu/h)
PTAC <7,000 EER = 11.7
7,000-15,000 EER = 13.8 - (0.300xCap)
>15,000 EER = 9.3
PTHP <7,000 EER = 11.9
COP = 3.3
7,000 to 15,000 EER = 14.0 - (0.300xCap)
COP = 3.7 - (0.052xCap)
>15,000 EER = 9.5
COP = 2.9
Non-standard (replacement) Minimum Efficiency
(No change from existing EE Regulations)
Equipment Cooling Capacity (Btu/h)
PTAC <7,000 EER = 9.4
7,000 to15,000 EER = 10.9 - (0.213 x Cap)
>15,000 EER = 7.7
PTHP <7,000 EER = 9.3
COP = 2.7
7,000 to 15,000 EER = 10.8 - (0.213 x Cap)
COP = 2.9 - (0.026 x Cap)
>15,000 EER = 7.6
COP = 2.5

"Cap" refers to cooling capacity in kBtu/h

Energy performance test procedure

The test methods used to determine efficiency is:

CSA C744-04, Standard for Packaged Terminal Air-Conditioners and Heat Pumps

The standard is available from:

Canadian Standards Association
5060 Spectrum Way, Suite 100
Mississauga ON L4W 5N6
Tel.: 1-800-463-6727
In Toronto, call 416-747-4000

Effective dates

This amended regulation will come into effect on January 1, 2012.

Verification requirements

As required for all regulated equipment, PTAC/HP must have efficiency verification labels that indicate a third party has verified the energy efficiency ratings and capacity ratings.

Labelling requirements

According to the requirements in CSA C744-04 Section 10.4, non-standard (replacement) units are to indicate that they are not to be used in new construction.

Importing reports

A dealer who imports these products into Canada must include the following information on the Customs release document:

  • Model number
  • Brand name
  • Name and address of the dealer importing the product
  • Purpose for which the product is being imported (i.e. for sale or lease in Canada without modification; for sale or lease in Canada after modification to comply with energy efficiency standards; or for use as a component in a product being exported from Canada)


The proposed changes are harmonized with requirements in the United States.
