On February 21st, ComfortStar announced that Choice R-421A is approved as the only acceptable R22 alternative refrigerant for all ComfortStar MIA/MIH-NCRdry-nitrogen-charged Air Conditioning units. We are very excited that Choice R-421A is the ONLY R-22 direct replacement covered under warranty for residential A/C by any OEM to date. We feel that this is a major step in the evolution and adoption of Choice R-421A as the preferred R22 replacement in the marketplace.
ComfortStar mentions the following reasons for approving R421A as the only acceptable R22 alternative refrigerant for use in their equipment-
-R421A is an environmentally friendly non ozone depleting replacement for R22
-R421A can replace R22 without modification-
-R421A no hydrocarbons such as butane, and is rated “A1” by ASHRAE
-R421A is non flammable and rated A1 by ASHRAE
-R421A can be used with Mineral, AB, or POE oils*
-R421A is comparable to R22 in terms of performance and pressures, approximately 1% higher at 95°F

*If there is a vertical height difference of 20 feet or more between the evaporator and condensor, the system must be converted to POE.

According to the EPA’s memo (2012 to 2014 Allocation Overview Memo), the EPA will continue to use the same HCFC-22 baseline as established in the 2011 Interim Final Rule. The Final 2012 – 2014 Allocation Rule will provide fewer HCFC-22 consumption allowances relative to the 2009 Final Rule and the same percentage of baseline for HCFC-22 production allowances relative to the 2009 Final Rule.
