Large air conditioners – upcoming requirements

These requirements are not yet in force. They will apply from January 1, 2026.

Energy Efficiency Regulations

Regulatory definition

Large air conditioner, a commercial or industrial unitary air conditioner with a cooling capacity of at least 19 kW (65,000 Btu/h) but less than 223 kW (760,000 Btu/h). It does not include a single package vertical air conditioner.

Compliance date

Manufactured on or after January 1, 2026

For models manufactured prior to January 1, 2026, refer to the Regulations

Testing standard

CSA C746-17

10 C.F.R. Appendix A - Appendix A to Subpart F, Part 431 of Title 10 to the United States Code of Federal Regulations, entitled Uniform Test Method for the Measurement of Energy Consumption of Air-Cooled Small (≥65,000 Btu/h), Large, and Very Large Commercial Package Air Conditioning and Heating Equipment, as amended from time to time.

Energy efficiency regulations by province

Some provinces also have their own energy efficiency regulations for many of the federally regulated products – find out which ones!
