All Marvair packaged heat pumps and air conditioners are tested according to ARI standard 390, "Performance Rating of Single Package Air-conditioners and Heat Pumps", and listed in the AHRI Single Package Vertical Units (SPVU) directory. ARI standard 390 is a product classification developed by ASHRAE 90.1-2004 and the Air Conditioning Heating & Refrigeration Institute (AHRI). The classifications - SPVAC for air conditioners and SPVHP for heat pumps - are referenced in the ASHRAE standard 90.1-2004. ARI standard 390 determines cooling efficiency as EER and heating efficiency as COP. All certified ratings for performance and efficiency are according to ARI 390. Performance minimums for SPVU's in ASHRAE 90.1-2004 can be found in table 6.8.1.D. A detailed description of the reasons that ARI created a new standard for our equipment can be found in the ARI 390 Marvair Sales and Marketing Notice dated 4.06.
