Whistling

A whistling or bubbling sound coming from your air conditioner usually signals a refrigerant leak. Refrigerant is a vital part of your system. The liquid/gas is responsible for turning the hot air in your home into cool air. Unfortunately, refrigerant is a toxic substance and should only be handled by a certified professional. If your air conditioner is whistling and you suspect your system has a leak, contacting a Falls Church VA air conditioning expert to inspect and repair the malfunction is your next step.
