How To Troubleshoot Common Furnace Issues

Book A Free Consultation

Noticing that your furnace isn’t working properly is never fun, especially in the dead of winter. It’s important to understand how to troubleshoot common furnace issues, and to know when it’s time to contact a professional technician.

Here are 4 common furnace issues that may occur, and how to troubleshoot them.

1. Thermostat Batteries

Does your thermostat require batteries and, if so, have you replaced them recently? Many homeowners are unaware that their thermostats have a battery that you can access once it’s removed from the wall.

2. Dirty Filter

When was the last time you replaced your furnace filter? If your filter is dirty and clogged up, it is important to replace it with a new filter. Dirty filters will make your furnace work harder to move the air through your home and, over time, it could reduce the overall lifespan of your furnace. You may then reset your furnace using the instructions below.

3. Snow In Vent

Has the snow built up and plugged your exterior furnace vent? Be sure to look directly into the pipes to see if the snow has infiltrated the pipe or elbow. You may use something flexible like a piece of garden hose to push the snow out. You may then reset your furnace using the instructions below.

4. No Power To Furnace

Could someone have accidentally turned off the power switch to the furnace? Look for the power switch, typically located not too far away from your furnace, and make sure it is switched on.

How To Reset Your Furnace

Find the switch or electrical breaker to your furnace and turn it off. Wait 2 minutes and then turn it back on. Make sure your thermostat is set to “heat” and the temperature is set above the room temperature. The furnace may take up to 5 minutes to start heating again so be patient.

Is it time to contact a Heating Professional?

Do you smell gas?

Do not attempt to correct this problem on your own. If the odour is very strong, have all occupants exit the home and call 911 to report it. If it is a very faint odour, you may want to call a heating professional to look at resolving the issue.

Do you smell burning?

If you smell burning when the furnace is turned on, this could be a sign of blower and airflow trouble. Turn the furnace off and call a heating professional.

Is the furnace making any loud or unusual noises?

This may be a sign of a serious problem. Contact a heating professional to fix this issue before any damage is done to your equipment or you are left with no heat.
