The Association of Home Appliance Manufacturers (AHAM) verifies the energy use and
internal volume of refrigerators, combination refrigerator-freezers and freezers.
Since 1967, we've used outside labs to test products, and today you'll find the
AHAM Mark on a variety of appliances. Refrigerators, combination refrigerator-freezers
and freezers that are part of the AHAM Verification program bare an AHAM Mark on
the serial plate located inside the appliance. You may use this online searchable
directory to locate a model that is right for you.
