If you’ve lived in Bromall, Pennsylvania, long, you know it’s a good idea to test your furnace well ahead of cold weather. The first time the temperature drops, everyone in town will switch on the heat. For some people who didn’t think ahead, the heat won’t come on. Heating and air conditioning companies will be swamped with calls, and there are only so many technicians available. Some families will be stuck shivering in the cold while they wait their turn for service. But what happens if you switch your thermostat to heat on the first fall day, and you find out you have a problem? Here are some reasons your furnace might not be working.
Even if you have a gas furnace, it still requires power. If you switch on your thermostat and nothing happens, you might have loose or corroded wires in your unit or in the thermostat. Make sure your thermostat is set to heat, check your electrical box for a blown circuit breaker, and examine wiring leading to your furnace. If you see loose wires, contact an expert immediately.
Pilot Light Is Out
If the blower goes on but all you get is cold air, check to see if you can see the blue flame of the pilot light. If you don’t see a flame, the furnace may simply need to be relit.
Filters should be changed every 30 to 90 days. Dirty filters make your furnace work harder to push out warm air, which wears it out faster. If your furnace doesn’t seem to be putting out much heat, check the filters. If your furnace frequently switches between hot and cold, that also may indicate a clogged filter.
If your furnace thumps, bumps, or squeals, it may have mechanical issues. Call an expert right away so a mechanical issue doesn’t lead to system failure.
Have your heating and air conditioning systems checked twice a year to prevent major issues. With regular maintenance, you’ll never have to wonder if your heater is ready for the cold weather ahead.
