If you have a gas furnace, you might find that it isn't operating with the same vigor it once had. This could from the thermostat, filter, or any of the furnace's mechanisms. Here are some tips for troubleshooting it in order to figure out what repairs need to be done.

Clean or Remove the Air Filter

Before you do anything else, make sure the air filter is clean when your gas furnace is not working properly. Many different issues with a furnace come down to the filters being clogged. This is such a simple task that makes such a big difference. The filters are in a furnace to prevent debris and dander from getting into the air being pushed through the vents, but the filters can also get clogged. If the filter is reusable, remove it and clean it thoroughly. Allow it to dry before replacing it. With a disposable filter, you just need to throw it out and put a new filter in the furnace.

Check the Thermostat

Gas furnaces often have issues due to very simple problems, such as the thermostat. Are you sure the batteries in the thermostat are still good? This is an easy thing to check, and minor problems can often be the only thing wrong with the furnace. After you check if there are fresh batteries, test out the thermostat or re-program it to make sure it is working. If it is having problems when trying to program it, it might be time to call an HVAC technician to replace it or repair it.

Verify That it Has Power

Another simple thing you can check is that the furnace is being supplied with enough power. Gas furnaces use pilot lights to power them, so that is a good thing to check first. This may seem very obvious, but it is one of those things homeowners often overlook. If the pilot light is supplying power to the furnace, and you are still having heating issues, it is time to contact a professional. Other issues with the furnace can be dangerous to inspect and repair on your own. It is best to contact a professional who can inspect and maintain the furnace and let you know the problem in the process. If you need major repairs or a new furnace, they will let you know.

Speak to a company that offers heating and cooling services, such as those at Pompeii's Custom Plumbing, if you have any questions about possibly replacing your current furnace for one with less problems.
