The clock is running out for old air conditioning systems that use R-22 refrigerant. If you aren’t certain what the R-22 phaseout is or how it affects your air conditioning system, here’s a quick rundown:
R-22, sometimes called Freon (a brand name), is an outdated refrigerant blend that was used for decades in air conditioning systems. Because R-22 creates ozone-depleting substances, the US Environmental Protection Agency started a process of gradually phasing-out use of this refrigerant blend to replace it with R-410A (a.k.a. Puron), which is not only healthier for the environment, but is a more efficient refrigerant blend for heat transfer.
The phase-out is now reaching its conclusion. As of 2020, professional HVAC technicians will no longer be permitted to use R-22 for any repairs to air conditioning systems, even using reclaimed refrigerant. So this means…
Spring is the best time to schedule annual
