Furnace troubleshooting is a serious topic since winter can seem to stretch on forever. It’s not unusual in parts of the U.S. to have our furnace running from October until May. So, when your furnace stops working and you don’t know what the problem is, this can be a very frustrating experience.

Thankfully, you have service.com in your pocket.

Not only will we give you furnace troubleshooting tips, but we will also tell you the easiest way to get a reliable HVAC contractor over to your house to fix the problem if you can’t or don’t want to deal with furnace troubleshooting.

Before you read these tips, remember there are some safety considerations. If you have a gas furnace, be careful. Gas furnaces can cause deadly explosions if not handled properly.

If you’re not sure about the safety precautions required to work on a gas furnace, go to service.com right now. We’ll get the next available heating contractor with a great track record, and you’ll keep yourself, your family, and your home safe.

Top 3 Furnace Troubleshooting Tips

1. Check for Leaks

By far one of the most important furnace troubleshooting tips we can give you is to check for leaks around your furnace. Do you smell gas? This could mean you’re dealing with a gas leak.

Shut off your gas furnace immediately (you always should do this before working on a gas furnace). Contact an HVAC pro to fix it. While you wait for their response, turn off the gas supply valve and avoid turning on any lights or lighting matches.

If you see water around your furnace, this could mean you have a clogged line. You can’t really mess with this by yourself because you’ll need an HVAC pro who also has plumbing experience.

2. Check Your Thermostat

One of the most helpful furnace troubleshooting tips we’ll give you is to check your thermostat. If it’s not set correctly, or if it’s faulty, it might not be triggering your furnace to turn on.

While this seems so simple, it’s common for homeowners to worry that something is wrong with their furnace when in fact it’s just the thermostat. This is a much easier and cheaper fix than a broken furnace!

3. Check for Debris

When is the last time you cleaned the inside of your furnace or your ventilation system? If the filter is dirty, it will need to be cleaned. If the filter is totally clogged, you’ll likely need to replace it.

You should also check the blower, pulleys, and belts for debris. If the filter is dirty, it’s likely that these are, too.

We included this as one of the top furnace troubleshooting tips because all of this will affect how well your furnace runs. It can also be the cause of a furnace that keeps kicking on and off repeatedly without actually heating the house.
