A homeowner in Allen, TX called about their upstairs HVAC system's fan running constantly. The fan wouldn't shut off on its own, which can waste energy and put extra wear on the system. Our team diagnosed the problem and found fault codes pointing to issues with the mitigation board and sensor. Lovejoy HVAC replaced both faulty components to restore proper system operation. The upstairs unit now cycles the fan correctly, turning on and off as needed to maintain comfortable temperatures.
