The Importance of Properly Sized Furnaces

There’s a common misconception among homeowners that “one-size-fits-all” when it comes to furnaces. Though there are a wide variety of different furnace types and sizes available on the market, people think that as long as the furnace can fit in their homes it will perform just as well as any other. This is not the case. Furnace size is actually a very important consideration when it comes to installing it in your home. If your furnace is not sized correctly, you may find yourself dealing with a whole slew of problems that could have been avoided. Let’s take a look at what can happen when your furnace is too large or too small.

Too Large

The first thing that you need to understand about furnaces and size is that each furnace is designed to operate on a cycle. This heating cycle is calibrated to heat a specific amount of space in an optimal way. If the furnace installed in your home is too large, then it will put out far more heat than that amount of space needs. This will cause the system to shut down before its full cycle is completed, a behavior that is appropriately named “short cycling.” Short cycling puts a lot of wear and tear on the furnace that it wasn’t designed to handle, eventually leading the system to break down.

Too Small

A furnace that is too small will also have problems with its cycle length, but in this case it will be forced to run for too long. The furnace does not have enough output to serve a space that large, so it will stay on for far longer than it was designed to do in an attempt to heat the home. This will also lead to eventual breakdowns from wear and tear.
