Proper Servicing

Servicing Systems with R-22
While R-22 remains available for servicing equipment made before 2010, it is important to know that supplies of R-22 will become more limited over time.

Working with a qualified service technician who will provide ongoing, regular service to your system is an important measure for maintaining its efficiency and refrigerant charge, as well as reducing your system’s impact on the environment. To identify a qualified service technician, go to HVACR Advice to locate local technicians certified through North American Technician Excellence (NATE).

Technicians servicing R-22 air conditioning systems must have EPA Section 608 certification and carry a card verifying this credential.

It also is illegal for them to intentionally release any refrigerant when making repairs. To avoid emitting refrigerants, technicians must use EPA-certified refrigerant recovery equipment during service.

Be sure to request that service technicians locate and repair leaks instead of "topping off" leaking systems. This protects the ozone layer and saves you money by optimizing the performance of your existing equipment.

It is important to note the newest refrigerant used in home air conditioning systems today is R-410A, and it cannot be used in any system not specifically designed for it.
