Heat pump equipment that use R22 refrigerant are no longer manufactured. Recycled gas can only be used. Parts are very hard to come by which makes them expensive. | By 2015 the use of all HCFCs including recycled materials will be banned as well as stockpiling of reclaimed gas. | Replacing existing R22 equipment with new inverter style R410a air conditioning systems improves efficiency by over 30%. Increased efficiency equates to less energy consumption, lower energy costs and lower CO2 emissions. |
