It’s that time of the year when many consumers find themselves in the market for a new room air conditioner.  Upon walking into a store to purchase one, one of the first things a consumer may notice is the AHAM Verifide label on the product’s box.  Room air conditioners carrying the AHAM Verifide mark have been tested by an independent laboratory to verify that the unit will perform according to manufacturers’ claims for cooling capacity in British Thermal Units (BTUs), Energy Efficiency Ratio (EER) and electrical energy in Amps.  Additionally, those models carrying the ENERGY STAR logo have been rated as being 10 percent more efficient than non-ENERGY STAR-qualified room air conditioners.

Ralph Hudnall, AHAM’s Director of Product Certification and Verification, explains that the independent laboratory’s testing conducted on room air conditions are designed to be as close to the consumer’s use as possible, and each model tested undergoes the exact same test to ensure uniformity.

Ralph explains, “At the lab, there are two adjoining rooms with one room configured as though it’s outdoors (hotter) and the inside room is the room that is to be cooled. Various sensors are set up to make sure the environmental conditions are correct and each unit is operated for 24 hours.?? Upon completion of the tests, the results are verified against the manufacturer’s claim and, if approved, the unit is given the AHAM Verifide seal.
