R-22 Conversion

R-22 or Freon helps produce cold air in HVAC systems and as of January 1, 2020 the EPA has mandated no longer be used. The phase out of R-22 has been a long-time coming and was in progress for over 30 years.

What does this mean for you?
Chances are if your unit is more than 8+ years old it most likely is using R-22 if not previously converted. If your unit is cooling as intended you might be ok for now but before the year is up you will need to consider switching R-410A. Not only is it more expensive to get R-22 now but older systems are at risk for leakage of this dangerous substance. Luckily we have done many of these conversions and are here to help you! Our technicians are fully licensed, insured, and EPA certified you can rest assured it will be done properly and safely.

What does converting R-22 to R-410A entail?

  • Evacuate the entire unit (vacuum out all R-22 refrigerant)
  • Flush out traces of R-22 and wait for the system to dry. Sometimes multiple flushes are needed to ensure all R-22 is out of the system.
  • Replace the accumulator, compressor, and expansion valves with parts that can handle R-410A compatible refrigerant.
  • Finally recharge the system with R-410A
  • Test system for leaks and confirm it’s operating correctly
