If your air conditioning system or heat pump was built and installed before 2010, it likely contains R22, an ozone-depleting refrigerant that is now phased out.
While you can still use existing R22 in your current air conditioner or heat pump, future repairs will require you to make some important decisions about your HVAC system.
As always, if you have questions, give us a call at (978) 834-0849.
