How Often Do Furnaces Need to Be Replaced?

Most furnaces last about 10-15 years before they need to be replaced; the actual length of time varies depending on several factors. If you’ve never had your furnace serviced or cleaned in the past few years, it could be an indication that your furnace is getting closer to needing replacement (if it hasn’t needed replacement already). Dirty or clogged filters can also increase energy costs and other annoying problems like poor indoor air quality.

Some of the common signs that your furnace might be getting ready to be replaced, and then I’ll talk about several factors that can affect how often a stove is replaced.

First off, it’s essential to realize that most furnaces are only expected to last about 10-15 years before needing replacement. This doesn’t mean that they have a “use by” date or anything like that; instead, it just means that after 10-15 years of regular use (and not too much neglect), most furnaces will need replacing due to wear and tear issues. In some cases, an older furnace may keep chugging along for longer, but this is rare.

Several factors can affect how long a furnace lasts before needing replacement. For example, if you’ve had your furnace installed in the past ten years but haven’t ever had it serviced or cleaned, then there’s a decent chance that it might be on its way out. Why? If you’ve never bothered having your furnace cleaned or serviced, then that could be why it seems to be breaking down so often. Almost every HVAC contractor will recommend getting your furnace serviced at least once per year – more frequently if you have pets or smokers in the house – and some even recommend having an annual checkup twice per year to catch minor problems before they become big ones.

Also, if you’ve had your furnace installed in the past ten years or so and it hasn’t been serviced or cleaned (and there are no pets, smokers, etc.), then that’s another sign that you might need to start thinking about replacing it soon. It’s not quite as crucial for furnaces to be serviced as it is for air conditioners, but having your furnace checked out on an annual basis can still help increase its lifespan.

Another significant factor is how often you use your heating system. This is probably fine if you only run the heater during the winter season (or whenever there isn’t much of a natural temperature change). Still, if your family likes to turn the heat up throughout the year (and it takes a while to warm up your house), then heating-related problems can occur more frequently. This is because your furnace won’t have time to cool down when it’s not in use; this will eventually wear out various components and increase the chance of something going wrong with your furnace in the future.
