Oversized Furnaces and the Issues They May Bring to Your Home


Share This Post

When buying a furnace for your home, a key consideration is to ensure that it fits perfectly in your home. However, not all homeowners are aware that an oversized furnace can have adverse effects that may compromise comfort and efficiency inside the property. Check out the common issues you may encounter when you have an oversized furnace:

Lower Home Efficiency

One of the most common issues with oversized furnaces is that they can lower your home’s efficiency. When a furnace is too large for your home, it short cycles, turning on and off more frequently than it should. This causes the furnace to work harder than it needs to, leading to decreased efficiency and increased energy costs.

Inadequate Heat Output

An oversized furnace can also lead to inadequate heat output, leaving your home feeling cold and uncomfortable. This is because an oversized furnace can’t produce enough heat to adequately warm your home, which can result in the furnace working harder than it should. This can also lead to increased energy costs and decreased comfort levels.

Poor Air Quality

An oversized furnace can also lead to poor air quality in your home. When a furnace is too large, it can cause the air to become stagnant, which can lead to dust and other pollutants accumulation. This can lead to respiratory problems and other health issues.

Reduced Lifespan and More Frequent Disrepair

An oversized furnace can also lead to a reduced lifespan and more frequent disrepair. This is because when a furnace is too large, it can put unnecessary stress on the components, leading to them wearing out more quickly. It can also lead to more frequent repairs and replacements.

What To Do if You Have An Oversized Furnace

If you have an oversized furnace, there are a few things that you can do to address the issue. The first is to have a professional furnace technician come to your home to inspect your furnace and make recommendations for how to address the problem.

Another option is to upgrade to a smaller furnace. This can be a more expensive option, but it can be worth it in the long run. Upgrading to a smaller furnace can lead to improved energy efficiency, improved air quality, and a longer lifespan for your furnace.

Other Tips to Choose the Right-Sized Furnace for Your Home

If you are considering upgrading to a smaller furnace, there are a few things that you can do to ensure that you choose the right-sized furnace for your home.

First, you should size your furnace according to the square footage of your home. You can use a furnace sizing calculator to help you determine the right size for your home.

You should also consider the climate where you live. If you live in a colder climate, you will need a larger furnace than if you live in a warmer climate.

Finally, you should also consider your family’s needs. If you have a large family, you will need a larger furnace than if you have a small family.

To Sum Up

It’s important to make sure your furnace is the right size for your home. An oversized furnace can cause a number of problems, including increased energy costs, shortened furnace life, and uneven heating. If you’re not sure what size furnace you need, talk to a heating and cooling professional.
