R22 Refrigerant

Was your air conditioner system installed in 2010 or earlier? If so, it probably runs on R22 refrigerant. R22 is currently being phased out of production because it contributes to ozone depletion and global warming.

Before the clock runs out, turn to Petro Home Services for R22 replacement services and answers to all your questions about air conditioning systems. We have EPA-certified technicians on hand to discuss your needs and options, including R22 refrigerant draining.

Why is R22 being phased out?

R22 is a greenhouse gas that contributes to the depletion of the Earth’s ozone layer and to global warming. Since we rely on the ozone to absorb harmful UV radiation, it’s very important to pinpoint and eliminate the use of greenhouse gases whenever possible. The R22 phase-out is occurring in accordance with the U.S. Clean Air Act and the Montreal Protocol on Substances that Deplete the Ozone Layer.

How do I know if my air conditioning system uses R22?

If your air conditioner was installed before 2010, it probably uses R22. Check the nameplate on the unit to find out what type of refrigerant is being used.

When is the R22 phase out taking place?

R22 will be completely phased out by January 1, 2020. No new or imported R-22 will be allowed in the U.S. after this date, and technicians will only be able to use recycled, reclaimed, or previously produced R22 to service equipment.

• • Continue using R22: R22 can still be used to service existing air conditioners, but supplies will be more limited and more expensive as the refrigerant is harder to source. Make sure your air conditioning technician repairs damaged refrigerant lines instead of merely topping off leaky air conditioners. Be aware that 1) older AC models that use R22 may also not be running at peak efficiency, and 2) the cost of R22 will continue to increase as it becomes less available.

• Use a “drop-in” refrigerant: There are “drop-in” R438a (MO99) OR  R421a refrigerants that can be used in place of R22. Most work okay but will result in decreased reliability and performance. For this reason, you should only use drop-ins for quick, temporary repairs and have a different long-term replacement plan in mind.
