Vermont winters don’t give your furnace much room for error. If yours has been acting up, you’re probably asking the same question a lot of homeowners in Franklin and Chittenden counties ask this time of year: do I need a new furnace, or can I have this one fixed one more time?
The good news is some clear signs separate a simple repair from a furnace that’s on its way out. Here are the five we look for most.
It’s 15 to 20 Years Old
Most furnaces are built to last 15 to 20 years with regular maintenance. If yours is in that range, it’s not necessarily broken, but it’s working harder than it used to, and it is getting closer end of life. Older units also lose efficiency each year, which means you’re paying more to get the same amount of heat.
If your furnace is pushing 20 and it needs a repair, that’s usually the point where replacement starts to make more sense than another fix.
Your Heating Bills Keep Climbing
A furnace loses efficiency as it ages, even with good maintenance. If your energy bills have been creeping up year over year and your usage hasn’t changed, the furnace itself is often the reason. Newer high-efficiency furnaces can cut heating costs noticeably, especially in a climate like ours where the furnace is running for months at a time.
You’re Calling for Repairs More Than Once a Season
One repair a year is normal wear and tear. Two or three in a single heating season is a pattern. At that point you’re paying for parts and labor on a system that has run its course. A good rule we use with customers: if a repair costs more than a third of what a new furnace would cost, or you’ve had multiple breakdowns in the last year or two, replacement is usually the smarter investment.
Some Rooms Are Warm and Others Aren’t
Uneven heating, cold spots, or rooms that never quite get comfortable no matter how high you set the thermostat are often signs that a furnace can’t keep up anymore. This can point to an undersized unit, worn out, or a unit losing the ability to distribute heat evenly through the house. A new furnace properly sized for your home fixes this in most cases.
Strange Noises, Smells, or Visible Wear
Banging, rattling, or screeching sounds, a burning smell when it kicks on, yellow instead of blue burner flames, or visible rust and cracking on the unit are all warning signs. Some of these are simple fixes. Others, especially anything involving the flame or exhaust, can point to a cracked heat exchanger, which is a safety issue, not just a comfort one. If you notice any of these, don’t wait on it. Call us and we’ll take a look before it becomes a bigger problem.
Repair or Replace? A Quick Way to Decide
If your furnace is under 10 years old and this is a first-time issue, repair usually makes sense. If it’s over 15 years old, has needed multiple repairs recently, or you’re seeing two or more of the signs above, it’s worth getting a straight answer from someone who isn’t just trying to sell you a furnace.
