Large air conditioners, and condensing units

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.

Large condensing unit, a commercial or industrial condensing unit that is intended for air conditioning applications and that has a cooling capacity of at least 40 kW (135,000 Btu/h) but not more than 70 kW (240,000 Btu/h)

Compliance date

Manufactured on or after January 1, 2018 for large air conditioners
Manufactured on or after December 31, 1998 for large condensing units

For models manufactured prior to January 1, 2018, refer to the Regulations
