Your furnace works hard to keep you and your family comfortable during cooler temperatures. As the chill of winter sets in, this is when your furnace will be put to the ultimate test. If you experience problems with this important piece of equipment, you may be left wondering if you can get by with minor repairs or whether you’ll have to replace it. One of the most common questions homeowners ask is, How Long Will Your Furnace Last Understanding the typical lifespan of a furnace can help you plan for maintenance, repairs, and eventual replacement before a breakdown leaves you without heat.

Most furnaces last approximately 15 to 20 years. However, if you’ve neglected to schedule regular maintenance services or failed to have your furnace repaired when necessary, the system might need replacing long before its estimated lifespan. The following are signs that your furnace needs to be replaced.

The Age of Your System

Within two years of its estimated lifespan, your furnace may begin to encounter a range of problems. The cost of repairs will most likely begin to increase over time, too. It can be difficult to evaluate the cost of repair vs. the cost of replacement. If a repair will cost Jcohvac half of the cost of a new furnace, it may be worth the investment to just purchase a new one.

Your Heating Bills Have Spiked

There are many things that could contribute to an increase in energy bills. If you’ve kept up with regular furnace maintenance annually and have had your air ducts sealed, your furnace shouldn’t cause a rise in energy consumption.

On the other hand, a steady increase in heating bills throughout the years may mean that your system is on its last legs. Whenever internal parts begin to wear, your electric bill will most likely go up. The extra money you’re spending on higher energy bills could go toward purchasing a new system.

You’ve Scheduled Frequent Repairs

During the last couple of years of their life cycles, furnaces often require several repairs. If you’ve scheduled more than two repairs within the last two years, it’s probably time to replace your system.

Your Home Doesn’t Feel Comfortable

If you’re constantly adjusting your thermostat to keep your home warm, the culprit may be your furnace. If your system isn’t able to distribute heat properly throughout your home, the issue is most likely either the furnace itself or a faulty thermostat. An experienced HVAC technician should be able to pinpoint the problem.

The Burner Flame Isn’t Blue

If your burner flame is yellow instead of blue, it could be a dangerous problem that needs to be addressed immediately. Any furnace flame color that’s not blue could indicate leaking gas or carbon monoxide. Exposure to either of these substances can be deadly. Signs that your home is being exposed to carbon monoxide from your furnace include:

• Rusting on pipe connections or the flue
• Soot streaks around the system
• A lack of upward draft in the chimney
• Moisture located on walls, windows, or other surfaces

Your System Is Making Unusual Noises

If you hear strange sounds such as rattling, banging, or popping whenever you turn your furnace on, it could mean that it’s reaching the end of its lifespan. Also, a blower that frequently turns on and off could be another sign that it’s time to have your system replaced by a professional.

Your Home Is Abnormally Dusty

If you constantly dust but never seem to be able to get rid of it, your furnace might not be doing its job of removing airborne particles from your home. The first thing to check in this scenario is your furnace filters. If they appear dirty or clogged, the issue could be remedied by simply replacing them with new ones. However, if you recently replaced your filters, the problem could be the furnace itself.

The Furnace Cycles Off Frequently

Your furnace will cycle on and off throughout the course of its normal operation. When the temperature of your home dips below the temperature set on your thermostat, your furnace should cycle on to bring temperatures back up. If your system seems to run non-stop or it cycles too often, it could be a clear sign that it’s not working as designed.
