How to Know When to Replace Your Furnace

Posted by Laura Landvik on Aug 20, 2014 4:09:00 PM

When Should You Buy a New Furnace?

Nobody really wants to spend a chunk of change on a new furnace, especially if it’s an unexpected purchase. But you can be somewhat prepared for that major purchase (mentally and financially) if you are aware of the signs that your furnace is nearing its end. You may want to replace your furnace if you experience the following:Replace your furnace

Strange Noises

If you’re hearing popping sounds, banging, squeals or rattling when your furnace fan is running, you may be headed toward the end of your furnace’s life. Often times these noises start late in the 15-20 year lifespan of a furnace and indicate significant problems.

Increased Repairs

Not only in price but in frequency of repairs. If your furnace repair costs are rising and you’re calling for repairs more often, that can be a sign that it's time to purchase a new one. Usually the up-tick in repairs occurs during the final two years of a furnace’s life.


If your furnace has an efficiency rating of around 80 percent, you could save a lot of money with a major efficiency upgrade, even if your current furnace isn’t quite dying. But you need to consult a Twin Cities heating and cooling expert to make sure that the upgrade is the right decision. Home size and fuel choice are other factors to consider when it comes to furnace efficiency and savings.

Home Comfort

If your home just doesn’t seem to warm up like it should or like it used to, or your home air quality seems to be on the slide, that too can be indicative of a furnace that isn’t functioning as it should.

It makes sense to consult your local Minnesota heating and cooling company first to see what they say about your particular situation and if another repair is worth the cost. If it’s not worth repairing, at least you’ve been paying attention to the warning signs, have put away a little extra in your rainy-day fund, and are better prepared for the investment of a new, high-efficiency furnace.
