How Long Should a Furnace Last?

If your furnace has kept your home warm for years, you might be starting to get nervous that it’s on its way out. At Meyer’s Companies, Inc., we’ve been working with furnaces since 1951. We’ve seen that a typical furnace lasts 15 to 20 years, but that’s just an average.

The lifespan of your furnace can be influenced by:

• Maintenance habits: Regular cleaning and professional tune-ups can add years to its life.
• Usage patterns: Furnaces that run constantly in colder climates may wear out faster than those used less frequently.
• Other factors: The quality of the brand, the initial installation, and the type of fuel it uses all play a role in its longevity.

If your furnace is getting up there in years, here’s what to start considering and looking out for before you are left in the cold.

Can Regular Maintenance Extend a Furnace’s Lifespan?

Yes, regular maintenance can help you get a few extra years out of your furnace, giving you time to plan and save for a replacement. Simple tasks like cleaning filters, inspecting burners, and checking ducts keep your system running efficiently and reduce wear and tear.

That said, it’s important to be realistic. While yearly maintenance helps prevent major issues and keeps performance steady, it can’t make an aging furnace last forever. Eventually, most older units begin to have issues.

What Are the Common Signs a Furnace Is Nearing the End of Its Life?

An aging furnace often gives you warning signs that it’s starting to fail. Keep an eye, and an ear, out for these common signs:

• Strange noises: Banging, rattling, or squealing sounds often indicate a mechanical problem that needs attention.
• Frequent repairs: If you find yourself calling for service more often, the accumulating costs can quickly add up.
• Rising energy bills: An unexplained spike in your heating costs may mean your furnace is losing efficiency and working harder to heat your home.
• Uneven heating: Cold spots or entire rooms that never seem to warm up are a clear sign that your furnace is struggling to distribute heat properly.

If you’ve noticed one or more of these signs, it may be time to start planning for a replacement before your furnace fails completely.

Should You Repair or Replace an Old Furnace?

When you start noticing issues with your older furnace, it might be your gut instinct to want to repair it rather than invest in a full replacement. However, there are some important factors to consider before making that decision. Let’s break it down:

• Cost of Repairs vs. Replacement: If repairs are becoming frequent and expensive, compare those costs to the price of a new unit. A replacement might seem like a big upfront expense, but it could save you money in the long run.
• Efficiency Decline: Older furnaces lose efficiency over time, which can drive up your heating bills. Upgrading to a high-efficiency model can lead to significant energy savings and lower monthly costs.
• Safety Concerns: An aging, malfunctioning furnace can pose serious risks, like carbon monoxide leaks. Keeping your family safe should always be a top priority.

While a repair might work as a short-term solution, a new furnace is often the more reliable, cost-effective, and safer option in the long run. It’s an investment in your comfort, savings, and peace of mind.

What Should You Look for in a New Furnace?

When it’s time for a new furnace, you’ll want to choose one that fits your home and budget. Start by selecting the right size and efficiency rating (AFUE) for your needs. A unit that is too large or too small will not heat your home effectively.

Look for modern features that improve comfort and save energy, such as variable-speed blowers and smart thermostat compatibility. As a Bryant Factory Authorized Dealer, Meyer’s Companies, Inc. can help you select a high-quality system with industry-leading warranties.
