Does your furnace keep shutting off for an unknown reason? With fall finally here and winter not far behind, the last thing you want is for your HVAC system to malfunction during one of those cold nights. These tips will help you troubleshoot your heating and cooling system so you can stay comfortable this season.

HVAC Troubleshooting Tips for Your Furnace

1. Check Your Air Filter

Your air filter is responsible for allowing efficient air flow through your HVAC system. To keep your system running smoothly, it’s important to have your filter changed every 30 to 90 days. When it gets too dirty, air can’t flow through it freely. This can cause your system to shut off randomly.

2. Inspect Your Windows

Your furnace will shut off when it determines the air surrounding the thermostat is sufficiently heated. If air quickly dissipates because of poor window seals, your home will get cooler sooner than it should, and the furnace will need to kick back on. Inspect the seals around your windows to check for cracks, tears, and other signs of wear and tear. Replacement weatherstripping is inexpensive and can easily be purchased at your local home improvement store. 

3. Check Your Thermostat

Your thermostat is responsible for monitoring its surrounding temperature and adjusting your HVAC system accordingly. If it’s old, needs new batteries, or is located in a particularly warm part of your home, it can cause your system to shut off frequently. Consider upgrading to a newer model or having it relocated to a more central part of your home or away from excess warmth.

4. Look at Your Furnace Size

Is your furnace too large for your home? While it might seem like purchasing a larger HVAC system will improve your home’s heating and cooling capabilities, it can actually cause your system to malfunction. When your furnace is too big, it can create a lot of heat in a shorter amount of time, so it cycles more frequently.
