During the winter, there’s always a chance your home’s heating system will act up or stop working entirely. Either way — the sudden loss of heat or a furnace that’s not heating adequately — this is something to avoid. Try learning some basic furnace troubleshooting steps. With that knowledge, you’ll have a better shot at figuring out what’s wrong and either fixing it yourself or knowing what to tell the HVAC service technician you call.
If Your Furnace is Struggling to Heat Your Home
This could the result of any of numerous issues. The air filter may need to be change; ductwork might be dirty or leaking air; the burners in your combustion heating system might be clogged; the blower motor might need to be cleaned and lubricated; or your heating system might be so old that it no longer can keep up with the challenge of heating your home. Each of these issues has a different solution, from the easy (changing the air filter) to the most difficult and expensive, replacing your heating system.
If the Heating isn’t Working at All
- Check that your HVAC system is getting power. Do this at the circuit-breaker box or at the on-off switch if your heating system has one. Is the thermostat set to “heat” and that the setting is above the temperature in your home? If the thermostat is battery operated, check the batteries.
- Ignition might be the problem, especially if you have an older furnace with a pilot light. Re-lighting the pilot might be all that’s necessary, though if the light keeps going out, or the electronic ignition (in a newer heating system) is malfunctioning, you’ll need a professional service call.
- If you hear banging or rattling in the furnace compartment before the system goes dead, it might be loose or detached parts in the blower motor, or a slipped belt. While you might be able to put the belt back on, you’ll need professional help for a faulty motor.
