Four Signs You Should Replace Your Furnace

Your furnace is one of the most important appliances in your home, and is the only thing that keeps your home livable during the winter months. Like all appliances, your furnace will begin to deteriorate over time, which can cause a number of complications for your property. Being conscious of some of the symptoms associated with an old and worn-out furnace can help make it easier for you to identify when you should begin thinking about replacement.

Increased Energy Costs

If your furnace is suddenly using much more energy than it was previously, it can point to some sort of mechanical issue or failure. Sometimes the fix is simple, like moving a carpet so that it is no longer covering a vent, but other times it can point to the overall age of your unit or serious complications that are not easily fixed. Upgrading to a newer model allows you to not only gain the benefit of a brand new unit that is still working at peak efficiency, but to also take advantage of new high-efficiency technologies that will likely reduce your energy usage even further.


If you've had an HVAC professional come in multiple times to take a look at your unit because of odd noises or performance issues that have arisen, you should probably start thinking about replacement. After a certain point, the amount of money that you've spent on repairs will outpace the cost of a replacement unit and, as mentioned above, newer units will be able to offer increased efficiency over your current unit, saving you money each month as well.


If your furnace is constantly turning on and off, your furnace has likely experienced a significant amount of wear. A clogged air filter, broken thermostat, or damaged internal components within the heating elements or motor can cause your furnace to cycle constantly. Not only does this negatively affect how well your unit can provide heating to the rest of your home, but it will place a great deal of stress on your unit and make further damage and complications more likely to occur.

Uncomfortable Temperatures

Finally, the last indication that you should talk to a contractor about replacing your heating system is if your home has begun to experience uneven temperatures, especially if this includes spots in your home that are completely cold. This indicates that your furnace is no longer able to produce and move around the same amount of heat as it previously could.
