Hagerstown Heating Tips: Troubleshooting Furnaces

Posted by Mike Corbett

If you want expert heating service in Hagerstown, call the professionals at Larry & Sons. You can count on us to troubleshoot your furnace quickly to figure out what the problem is whenever you are having issues. Here are some troubleshooting guidelines to keep in mind when you call for a repair.

One of the most common problems with furnaces is not turning on or providing enough heat. Always check the air filter first. Is it dirty, clogged, or did the filter door not get shut properly the last time it was changed? Make sure nothing is blocking vents if it isn’t providing enough heat, but if it won’t turn on, check the power source. There could have been a limit or safety switch that was accidentally set off.

Check your fuse box to make sure you don’t have a blown fuse. If your furnace has problems on a regular basis or has been consistently causing power surges, there could be an electrical problem. This could be a safety issue, so call a technician ASAP if this is happening.

For gas furnaces, there could be a problem with the pilot light. Make sure the pilot light is always blue and not flickering. If the pilot light doesn’t turn on or causes a loud banging noise, call a technician to diagnose the issue. If everything checks out, make sure the thermostat is on the right setting and temperature.

It could always be something simple like the thermostat setting, but call one of the Hagerstown furnace technicians at Larry & Sons whenever you cannot get your furnace to work properly.
