Signs Your Furnace Needs Replacing

Heating season is here, and for some of us that’s a bit of a problem. If your home heating system is on its last legs, this might be the season that it finally breaks down for good. Since you probably don’t want your furnace to die on you in the middle of the coldest season of the year, you’re going to need to replace it. If you aren’t sure whether or not your furnace is in need of replacement, read on for some of the most common signs.

Repair Spikes

The accumulated wear and tear from years of normal use eventually starts to cause various parts of the furnace to break down. Since each part of the system wears down a little differently, this can cause cascade failures in which multiple parts fail in a short time. A relatively healthy furnace doesn’t need repairs more than once every couple of years. With an older furnace, though, you may have to call for repairs every few months.

Efficiency Drops

The same wear and tear that causes repair issues also lessens the overall efficiency of the system. Older furnaces need to stay on for longer and longer periods of time in order to affect the same temperature changes, which in turn makes them more expensive to operate. If your furnace is costing more and more to operate, it’s time to replace it.


If your furnace is older than 20 years, it’s probably a good idea to replace it. Older furnaces are both less efficient and more prone to developing problems than newer system. Even if you can keep your furnace up and running past that point, it would be cheaper to install a newer system.
