The average life span of a residential furnace is about 15 to 20 years, if it is maintained properly. Carefully watching for warning signs and calling an HVAC company for maintenance or a repair when you spot an issue will help your furnace last longer and ensure you receive the maximum service from your system. For the best results, keep an eye out for the following five signs that will alert you it’s time for a furnace repair.

5 Warning Signs You Need a Furnace Repair

1. Unusual Sounds

A brand-new HVAC system will probably be pretty quiet, but after a few years, you may hear an occasional slight noise. If the bangs and squeaks get louder or more frequent—or you hear something you haven’t heard before—you probably need a furnace repair.

2. Odd Smell or Yellow Pilot Light

A natural gas furnace will give warning signs if you have a leak. If your pilot light is yellow instead of blue, or if something smells odd or rotten, immediately turn off your furnace and call an HVAC company. Don’t light matches, and turn off the lights in your home until the technician has arrived and resolved your problem.

3. Cold or Weak Air

If you have cold spots throughout your home, the blower fan may not be working properly, and the weak air flow may be causing the issue. You could also have a faulty heat exchanger or pilot light. A qualified HVAC technician can diagnose the problem and provide a solution.

4. Increased Energy Costs

If your furnace is getting old or needs maintenance, it may run longer or work harder to keep the home warm, and your heating bill will go up. If you haven’t recently raised your thermostat, but your bill has increased, it’s time to call a technician.

5. Excessive Dust

Every home accumulates dust. But if you notice you suddenly have more dust on your furniture than usual, or if you see it coming from heat registers when the furnace cycles on, your furnace could be the culprit. If you change your furnace filter every few months, the increased dust could be a sign that your duct work or blower fan needs maintenance.
