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 HVACRadvice.com 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.
