When a heating or cooling system malfunctions, any one of its three components — heat/cold source, distribution system, or thermostat — may be causing the problem. If the furnace or air conditioner doesn’t run, the malfunction is probably at the source. The furnace or air conditioner may have lost power. Fuel may not be reaching the unit. If the fuel is gas or oil, it may not be igniting. If the furnace or air conditioner turns on but the warm or cool air isn’t reaching the rooms of your home, the problem is likely to be the blower or distribution system. And a faulty control, or thermostat, could keep the system from turning on or could cause it to turn on and off repeatedly.Whatever the problem is, Ed’s HVAC is just one call away to help all your furnace and A/C needs.
