How to Troubleshoot a Furnace and When to Call a Professional

October 11th, 2021


Is your heating system in good shape? Is it up to the job of keeping you warm and comfy all through this fall and winter?

If you’re not sure, or even if you think it’s just fine, this is the perfect time of the year to schedule maintenance! Maintenance helps your heater work as efficiently and effectively as possible for as long as possible.

In the meantime, it’s a good idea to know how to troubleshoot a misbehaving furnace so that you can call in the professionals to get it fixed. Read on as we share some tips on how to do so.

Check the Furnace Filter

The air filter that comes with your furnace is in place to protect the internal components of that furnace from dirt, dust, and other debris that can get inside and damage its components.

However, this air filter can also get too clogged up. And when this happens, it restricts airflow, which can cause problems for the furnace. Homeowners should change their HVAC air filters every 1-3 months.

Turn Your Thermostat Down

For the best efficiency, try setting your thermostat to about 5 degrees above what the room temperature is. Setting it higher than this doesn’t help your furnace heat the room up any faster, it just makes the furnace run longer to try to achieve the desired temperature, which can be inefficient.

Check Furnace On/Off Switch

What if you go to turn on your furnace for the first time this fall and it fails to come on? This doesn’t automatically mean that it’s broken down. You or your HVAC professional might have turned it off at the furnace system itself so that it didn’t accidentally cycle on during a time you didn’t need it.

Check the Breaker Switch on Electrical Panel

Did your furnace just stop working? Check the electrical panel. It’s possible that your furnace overloaded its circuit breaker. This can even happen with a gas-powered furnace since it uses an electric ignition to start up.

Check Furnace Flame

A furnace flame/pilot light that has gone out is another reason that your furnace might not turn on. This can be the case that it’s time to call in a professional, as you don’t want to deal with gas lines or gas components on your own without the right training and expertise.

Ensure Front Panel Is Secure

Hear your furnace rattling? Its panel might be loose. This is typically something you can fix on your own with a couple of twists of a screwdriver. If you need more help though, please don’t hesitate to contact us.

Ensure Vents and Registers Are Not Blocked

Just like the clogged air filter we mentioned above, this can restrict airflow. When airflow is restricted, your heater has to run longer to try to do its job, which means it is running inefficiently.

Troubleshooting Your AC System

All the above steps are what you should do for a furnace before you give us a call, but these same steps can and should also be used for your air conditioner as well!
