There are several things that could go wrong with your furnace during the fall. Check out the top 7 HVAC problems that we regularly encounter and how to fix or prevent them.
Airflow Obstructions due to Dirty Air Filters
Though a persistent problem all-year round, dirty filters are especially problematic during the fall season due to higher activity of your HVAC system to maintain your home’s comfort. Air filters are your first line of defense against dust, pollen, mold, and other pollutants. A compromised air filter will restrict airflow and can cause your system to work harder and longer. This in return can lead to system breakdowns and higher energy bills.
How to fix / prevent: Check your filter monthly, especially during high use seasons like fall and winter. If your filter is covered in dust or you have changed it in more than 90 days, it’s time to swap it for a new one.
Thermostat Malfunctions
As we transition from summer to fall temperatures, your thermostat may fail to adjust correctly. Inaccurate or unresponsive thermostats can lead to poor heating performance, higher energy bills, or even complete system shutdowns.
How to fix/ prevent: If you own a programmable thermostat, make sure to reprogram its temperature schedule to the fall settings. Don’t forget to replace your thermostat’s batteries if needed to ensure accurate readings. A professional HVAC technician can also help you repair or even replace your thermostat.
Ignition problems
If you own a gas furnace, you may run into ignition and pilot light issues as you attempt to fire up your system during the first cold night of the fall. This means your furnace will fail to heat up at all.
How to fix/ prevent: Have a professional inspect and service your system for proper and safe reignition of your furnace.
Furnace exhaust pipe malfunctions
During the summer, debris like leaves, dirt, bird nests, or even insects can block the furnace exhaust pipe, particularly if the vent is on the roof or exterior wall. A blocked vent prevents the safe release of gases, which can lead to dangerous carbon monoxide buildup once the furnace is in use.
How to fix/ prevent: Regularly inspect the exhaust pipe for any visible blockages and have it cleaned professionally before the heating season starts.
Return Vent Blockages
If you close some vents or place some furniture near them, it can block airflow and strain your HVAC system.
How to fix/ prevent: Remove any blockages such as furniture and objects obstructing your return grilles. This can enhance consistent airflow and help maintain even heating throughout the home.
Clogged Drain Lines
During the fall, debris like leaves and dirt can make their way into your HVAC system’s drain lines, causing blockages and preventing it from properly removing excess moisture from the unit. This can result in water backup, potential leaks, and even mold growth.
How to fix/prevent: Shut off your system and clear any debris from around your outdoor unit. If you’re familiar with the process, you can flush your system’s drain lines yourself or call a professional for help.
Unusual Noises or Odors
You might hear rattling, banging, or squealing noises coming from your furnace. These noises can indicate mechanical issues such as loose parts, worn out belts, or dirty burners. Meanwhile, musty or burning odors can signal mold growth or electrical issues.
How to fix/ prevent: Never ignore these signs of complications in your furnace, which may worsen if left unaddressed. A professional can inspect the system and perform necessary repairs before the problems worsen.
