Packaged terminal air conditioners – May 2016

Technical bulletin on amending the standard

Webinar - June 2016

On April 30, 2016, Natural Resources Canada's Office of Energy Efficiency issued a Notice of Intent to align Canada’s EnergyEfficiency Regulations (the Regulations) for packaged terminal air conditioners (PTAC) with standards in the United States. This technical bulletin has been released to initiate the consultation process and to collect stakeholder views on the requirements being considered for PTAC.

Input received during this stage of the process will inform the development of the Amendment 14 proposal.  In addition, the department will undertake a cost-benefit analysis using the best-available Canadian market data to assess the economic and environmental impacts of aligning these standards and to ensure Canadian consumers and businesses benefit from its implementation.

The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I within approximately one year of this bulletin.


Packaged terminal air conditioners were first regulated in Canada in 1995.  On July 20, 2015, the United States Department of Energy (U.S. DOE) issued a final rule, which increased the stringency of the minimum energy performance standards (MEPS) for PTACs.

Natural Resources Canada (NRCan) is considering increasing the stringency of PTAC.  If implemented, this proposal would ensure the Regulations for packaged terminal air conditioners are aligned with those of the U.S. DOE.

This proposed amendment does not change the MEPS for packaged terminal heat pumps.

Product description

A packaged terminal air conditioner is generally a commercial product predominantly used in hotel and motels for cooling and heating. Standard size PTAC refers to equipment with wall sleeve dimensions having an external wall opening greater than or equal to 40.5 cm (16 inches) high or greater than or equal to 107 cm (42 inches) wide, and a cross-sectional area greater than or equal to 4,323 square cm (670 square inches).

Energy performance test procedure

NRCan is proposing that the following energy performance test procedure be referenced:

  • CSA C744-14 - Standard for Packaged Terminal Air Conditioners and Heat Pumps.

The test procedure can be ordered from:

Canadian Standards Association (CSA)
Telephone: 1-800-463-6727
In Toronto, call 416-747-4044

CSA energy efficiency standards are also available at no cost on their website. To access free standards you will first need to create an account to join the CSA Communities of Interest.

Energy performance standard

Table 1 – Proposed MEPS for packaged terminal air conditioners
Product type Cooling capacity Efficiency level
PTAC – standard size <7,000 Btu/h EER = 11.9
PTAC – standard size ≥7,000 Btu/h and ≤15,000 Btu/h EER = 14.0-(0.3 x Cap1)
PTAC – standard size >15,000 Btu/h EER = 9.5

1 Cap means cooling capacity in 1000s Btu/h at 35°C (95°F) outdoor dry-bulb temperature

Effective date

These Regulations will come into force six months after the date of publication in the Canada Gazette, Part II.

NRCan proposes that the updated standards will apply to PTAC that have been manufactured on or after January 1, 2017.

Verification requirements

There is no change proposed for the energy efficiency verification requirements for this product.

Reporting requirements

Energy efficiency reports

There is no change proposed to the reporting requirements for PTAC.

The Regulations apply to products imported or shipped inter-provincially for sale or lease in Canada. This report must be submitted, by the dealer, to NRCan before the product is imported into Canada or traded inter-provincially for the first time.

Import reports

There is no change proposed to import reporting requirements for PTAC.

Comments invited

The purpose of this bulletin is to provide stakeholders with technical detail required to comment on the requirements under consideration for packaged terminal air conditioners. 

Additional information on Canada’s Energy Efficiency Regulations including a current list of Standards Council of Canada accredited certification bodies can be found in the Department’s website.
