Current Standard

Air-cooled unitary air-conditioners and heat pumps manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(16), must meet the energy conservation standards specified in the Code of Federal Regulations at  10 CFR 431.97.


Current Test Procedure

To determine that air-cooled unitary air-conditioners and heat pumps that are currently manufactured or distributed into commerce are in compliance with DOE standards, manufacturers must follow the test procedure methods specified at 10 CFR 431.96.


Helpful Links

Compliance

DOE has established regulations on certification, compliance, and enforcement in the CFR at 10 CFR Part 429.  These regulations cover statistical sampling plans, certified ratings, certification reports, record retention, and enforcement.  More information on these regulations is available here.

Waivers
