Signs You Should Replace Your Furnace

Owning a home comes with ongoing costs and responsibilities. One that everyone must deal with at some point is furnace replacement.

While it is possible to invest in repairs (learn more at and keep the unit running for a while, eventually replacement will be necessary. Some of the top signs it is time to invest in furnace system replacement can be found here.

The Age of Your Furnace

The average furnace can last for 15 to 30 years in your home. One of the easiest ways to keep the unit running efficiently is by hiring professionals to provide regular maintenance and repairs annually. While this is true, it is also a good idea to look into furnace replacement when it reaches 15 years old. Keep in mind that the lifespan of an older furnace is also dependent on the fuel used to heat your home.

Some homeowners decide to install a new electric furnace rather than repairing an older gas system since they have a longer lifespan of between 20 and 30 years. Even though gas furnaces have a shorter lifespan, they also cost much less money to run when compared to electric options. Also, gas furnaces will heat your home faster than electric units.

You can find several ways to expand the lifespan of your furnace. One option is to replace the dirty filters regularly. Another option is to improve the temperature of your home without replacing your furnace is by sealing the doors and windows in your home, which will prevent the heat from escaping.

Loud Sounds During Operation

There are a few noises that indicate you need to repair or replace your old furnace. Some of the most common signs you may hear when replacing your furnace include humming, screeching, popping, and rattling. It may also be a good idea to switch from a furnace to a different heating source like ductless mini-split systems, heat pumps, or boilers, which can help you save money on your utility costs.

Temperature Fluctuations in Your Home

Have you noticed sudden or significant changes in the temperature from one room to another in your home? It is a good idea to call a professional to repair the unit or find the issue. However, if the temperature fluctuation is significant in some cases, a new unit may be required. As mentioned above, once a furnace reaches the 15-year mark, it won’t be as efficient, and it will lose the ability it has to distribute heat through your home evenly.

Soot Close to the Furnace Register

As a homeowner, the last thing you want is to find dust or soot in your kitchen, bedroom, or bathroom. Usually, dust and soot are related to dry air in your home. It could cause significant damage to your shelves, wood flooring, chairs, or couches when this happens. If you begin to notice the plants in your home dying, it is a sign of lower-than-normal moisture levels in your home.

Also, signs of more soot and dust are a sign that the furnace is over-producing carbon dioxide. Usually, a build-up of soot will be found close to the furnace’s grille and register. If this happens, it is a good sign you should replace the entire unit.

Don’t Wait to Replace Your Furnace

If you notice any of the above issues with your furnace, now is the time to invest in a replacement. The longer you wait to do this, the more issues that may occur. Being informed and knowing what to consider are the best ways to ensure that your furnace operates properly and that it will operate efficiently.
