When your heater isn’t working, it’s so easy to pick up the phone and make a call with an HVAC technician, right? Normally, your heating system malfunctions because of an issue that you might not have been noticed.

If you find that your furnace isn’t igniting, the problem might be any of the following:

Faulty Thermostat

Should you need a heating repair in Post Falls, ID when the problem is on the thermostat? A furnace that failed to ignite is a sign of an issue on your thermostat and a full system check-up is necessary. Be sure it is set to heat, the batteries are functioning, and the temperature is set correctly. Try all options and see if it works.

Gas Line Isn’t Working

Your furnace might not be igniting because it isn’t getting gas at all. Before calling for heating repair service in Post Falls, ID, make sure to check if your gas supply is operational and uninterrupted. When the gas supply to your heating system is disrupted, your system could lack the fuel needed to ignite. Finally, as soon as you notice a gas leak, call in an HVAC pro to evaluate the issue.

Filthy Air Filters

Have you changed your filters recently? Usually, when heaters don’t start up, the first thing to check is the air filter. There’s a good chance that your heating system won’t ignite when the airflow is restricted. See to it that your furnace filters are clean or have been changed, so your system can perform as it should.

We advise changing your filters monthly or as often as needed to ensure you’re breathing in clean air throughout the house. With clean filters, your furnace won’t have to work harder to meet your comfort demands.

Defective Ignition Source 

Furnaces ignite either of these two ways: through the pilot light or electronic ignition. The pilot light comes with a small flame that should burn consistently to let your furnace work. With an electronic ignite, an electric current goes through a lightweight metal alloy, and this ignites the air or gas that comes into your furnace.

Repeated clicking in small intervals means your igniter isn’t working and there’s no way for your furnace to function with a defective ignition source.

Tripped Breaker

Sometimes, the problem might not be in your system but on the power source. Especially for electric furnaces, you have to ensure that your system is plugged in and receives enough power to operate. You also want to check the breaker if it’s tripped or not.

Is It Time to Call an HVAC Technician? 

You surely don’t want to try any troubleshooting in your heating system unless you know exactly what you’re doing. In this case, it’s best to call an expert in heating repair in Hayden, ID (or someone local to you), to guarantee excellent results in your project.
