Fagone Plumbing, Heating & HVAC completed a multi-system HVAC installation in Salem involving a furnace, evaporator coil, and condenser replacement. After installation, the system experienced short cycling caused by thermostat incompatibility with the new R-454B refrigerant safety requirements. Our team diagnosed the issue, installed a temporary thermostat to restore operation, and identified the need for a compatible control solution to ensure proper system performance.
