What is refrigerant?
A chemical that produces a refrigerating effect while expanding and vaporizing. Most residential air conditioning systems contain R-22 or R-410 refrigerant. R-22 and R-410 are regulated by international controls under the Environmental Protection Agency.
Note: Equipment using R-22 will no longer be produced after the year 2010 which will increase costs due to limited availability. R-22 will no longer be produced after 2020. Homeowners with equipment using R-22 can schedule a consult with one of our experts to discuss upgrading to high efficient equipment using EPA approved R-410 refrigerant.
