Indicators That It’s Time to Repair or Replace Your Furnace


As the cold seasons approach, your furnace will soon be in the spotlight. Temperatures will drop, and your furnace usage will skyrocket to keep your home and water warm. Unfortunately, like all major appliances, your furnace isn’t getting any younger. Whether you’ve thought about it or not, something could go wrong that warrants a repair or a replacement.

We recommend conducting system checks before winter hits to ensure all your utilities function properly during inclement weather or blizzards. Your furnace is no exception. Below are a few signs that may indicate you need a furnace repair or replacement:

Age

The average lifespan of a furnace is 15-20 years, but well-maintained, high-quality furnaces may last longer. If your furnace is old enough to have had a prom date, it’s probably time for a replacement.

If your furnace is over 10 years old, expect a potential repair soon, especially if no maintenance has been done previously. Parts age, and rust and corrosion can take their toll. Check your furnace’s warranty and maintenance history; some warranties extend up to 20 years, which may cover the necessary services.

Noise

Your furnace should not double as a percussion instrument. It should make a low grumble when cycling, similar to a reluctant family member completing chores. Unusual noises like bangs, scrapes, booms, screeches, or thumps indicate that a repair or assessment is needed urgently. Loud noises can signal serious safety issues requiring immediate attention.

Efficiency

Is your heating bill increasing without additional usage? Your furnace might be to blame. Older furnaces often have efficiency ratings in the ~70 percent range, while today’s models can reach up to 98.5%.

An increased heating bill indicates a furnace needing repair. Identify the issue quickly; otherwise, you’re paying for wasted resources. Often, ductwork within the furnace is the culprit, although other factors may play a role. A repair can usually resolve the issue, but severe problems may necessitate a new furnace.

Sight and Smell

A distressed furnace often reveals itself through visual and olfactory cues. If you see water or gas pooling around your furnace, there’s an issue. While water is less dangerous, both require immediate attention.

If you smell gas, there may be a leak not visible to the eye. In such cases, turn off your furnace and its gas supply valve immediately, then contact a contractor. A gas leak poses a significant risk and must be addressed straightaway.

If you’ve determined that a new furnace is necessary, it may be a long-term win. A new furnace ensures your home is equipped with a safe, quiet, warrantied, and efficient system. Benefits include lower heating costs, no unexpected repair bills, higher home resale value, and greater peace of mind.
