Common Gas Furnace Issues

Thermostat Is Off

If your furnace doesn’t turn on, the first thing to check is the thermostat. Make sure that it’s working and that the settings are correct. Common thermostat problems include dead batteries, too much dust, and debris inside, and a tripped breaker.

Clogged Filter

If you haven’t changed the filter in a long time, it may be clogged with dust, dirt, and other debris. Your furnace has to work harder as it doesn’t have sufficient airflow, and it may even shut off prematurely. Change the filter if it’s clogged and set a reminder to check it every month to see if it needs to be replaced.

Noisy Furnace

If your furnace is making new and excessive noises, you should have it looked at right away by a licensed technician. You could otherwise end up with an expensive repair bill. Sounds it may make include loud banging, humming, or a high-pitched squeal.

Blocked Registers

Blocked registers can cause furnace issues. Make sure that they’re all open and give them at least 18 inches of space from furniture so that there’s proper airflow. Even a curtain on them can be a problem.

Faulty Electric Ignition

Modern furnaces have an electric ignition rather than a pilot light. If the electronic ignition fails, it may cause the furnace to rapidly turn on and off or just not start at all.
