Are you using a central AC that needs R22 refrigerant, an ozone ruining substance? You’re in for a stagger during the next HVAC service. Beginning December 1, 2020, production and import of R22 refrigerant is not allowed in the United States. AC or heat pump systems with faults necessitating refrigerant top up are greatly affected. You may be forced to decide between a large refrigerant bill or to change the aircon. Disregarding existing AC units that use it, the ban on creating and import of R22 applies to all others. The EPA also stopped the manufacture and assembly of new R22 AC or heat pump units. The move led to manufacturers of AC and heat pumps redesigning HVAC systems to use R410A. If an AC or heat pump was made and installed before December 1, 2012, there’s a likelihood that it used R22 refrigerant. This air conditioner may have writing on it that identifies the type of refrigerant to add. Due to the shrinking amount of R22 refrigerant, it is now no longer affordable. The lessening supply means you’ll be charged more for a repair that only uses R22 refrigerant than paying a small sum on a quality heat pump or AC system. Remember HVAC systems and heat pumps are not designed to utilize refrigerants. Refrigerant simply goes through a continuous number of coils. If your AC worker suspects a discharge, they should locate and restore the refrigerant spill instead of simply adding more to a leaking system. When it is the right moment to purchase a new aircon system to replace your seasoned one, you will benefit increasingly from getting one using R410A refrigerant and have some change. R410 is readily available which isn’t the case for R22 refrigerant.
