Professional Circuit Control Board Replacement
Your HVAC system’s circuit control board acts as the brain of the operation—coordinating signals between the thermostat, blower, compressor, and other components. When it fails, your heating and cooling system can behave erratically, stop responding to thermostat settings, or shut down completely. At OHA HVAC, Plumbing, Chimney and Fireplaces, we provide fast, expert circuit control board replacement in Fredericksburg and Fairfax, VA, NOVA and surrounding areas to restore full function and efficiency.
