With winter right around the corner, it’s imperative to have a fully functioning heating system to keep your home warm and comfortable. Your furnace isn’t meant to last forever, and when problems crop up, you’ll need expert help to determine whether repairs will suffice or replacement is necessary. Below are a few common signs that your furnace is malfunctioning and needs attention. 

4 Ways to Know Your Furnace Is on the Fritz

1. Age

The average lifespan of a properly maintained furnace is roughly 15 to 20 years. Review your records to determine when your furnace was installed. Even if your system isn’t actively malfunctioning, older units are more prone to failure. If you’re unsure of your unit’s age, an HVAC professional will inspect the unit and tell you how much longer you can use it, or install an updated model if necessary. 

2. High Energy Bills

If you notice a spike in your energy costs without changing your home heating habits, a furnace malfunction could be to blame. Damaged heating systems have to work harder to continue heating the house at the desired temperature, raising energy costs. 

3. Unusual Noises

furnaceLoud, constant, or atypical noises are another symptom of a malfunctioned heating system. Dirty furnace burners, clogged air filters, or improperly sized ducts will create loud bangs and pops. Broken blower motors will cause a squealing or metallic scraping sound. A qualified HVAC contractor will assess the situation and make the necessary repairs. 

4. Yellow Pilot Light

If your unit has a standing pilot light, it should burn blue. If oxygen flow to your pilot light is restricted, its flame will turn yellow. This is a sign of incomplete combustion, which makes the flame prone to blowing out and allows dangerous carbon monoxide gas to leak into your home. If you notice a change in the color of your pilot light, turn off your system and call an HVAC professional for assistance immediately. They’ll correct the issue by cleaning the air intake valve or by replacing your furnace with an electric ignition unit.
