5 Tips for Troubleshooting Your Furnace

It’s easy to feel panic when your furnace malfunctions or fails to keep your home warm. While you can never go wrong by calling a professional furnace repair Oshawa technician, there are a few things that you can check before making the call. This is because some issues aren’t as severe as you might think and by checking some of the key components of your furnace, you can avoid costly repairs and get your furnace back on more quickly.

1. Check Your Filter

Air filtration is one of the most important aspects of every heating and cooling system and dirty air filters are some of the most common but preventable furnace issues. Dirty air filters can worsen air quality in the home, reduce energy efficiency, and even cause your furnace to shut off entirely. Fortunately, air filters are easily accessible and easy to change. They typically need to be changed every one to three months. You will know when an air filter is dirty because it will be covered in dust, dirt, and other debris. The more you see, the more likely it is that the filter is the source of your furnace problem.

2. Watch the Thermostat

Sometimes furnace problems aren’t actually furnace problems but rather thermostat issues; sometimes, these issues aren’t actually issues at all. You may panic when your furnace refuses to kick on or heat your home but your thermostat may simply be on the wrong setting. It seems silly but you want to make sure that your thermostat is set to “heat” and that the temperature setting is higher than the current temperature in the home.

3. Confirm That the Breaker Is on

It’s also possible that your furnace has thrown a breaker switch and is no longer receiving any power. Find your home’s breaker box and locate the switch tied to the furnace. If there is no labelling, look for switches that are in the “off” position or that are sitting in between on and off. If your furnace switch is in the middle, simply move it all the way to “off” and then click it back on. If none of these are the cause of the issue, it may be time to seek a furnace repair from a professional.

4. Check the Blower Panel Door

There are doors on your furnace that cover the electricals and the blower and some furnace models have a safety mechanism in the form of an on/off switch that is triggered by the door. If the door isn’t on properly, the switch will stay off and your furnace won’t turn on.

5. Gas Valves and Pilot Light

Other possible and detectable issues are ones involving the gas valves and the pilot light. If your pilot light is off, it will need to be re-lit. If you are unable to re-light the pilot, make sure that all of your gas valves are on and that your furnace is receiving gas. There is a valve on the gas line to the furnace but if you have had gas work done recently, your main gas valve may be off as well.
