When it comes to choosing the right natural gas, oil, or electric furnace for your Mount Crawford, Broadway, or Crimora, VA home, did you know that furnace sizing can play a huge difference in the efficiency of your furnace as well as your overall residential heating comfort?

Don’t make the mistake of installing a heating system that will leave you constantly looking for a furnace repair service near you. Here’s why furnace sizing is important and how you can avoid suffering from oversized or unsized heating with expert heating and cooling contractor services.

How Does Furnace Sizing Work?

Furnaces are measured based on their heating capacity, which is expressed as BTUs (British Thermal Units). Furnaces can be as small as 40,000 BTUs or as large as 200,000 BTUs, but the average is about 100,000.

Many people assume that the more heating capacity or BTUs a furnace has, the better it will work in your home. Actually, this is incorrect! A furnace should be specifically sized for each individual home, and what could be the perfect sized furnace for one home might be causing lots of problems for another.

Finding the proper furnace sizing for your home involves considering a number of factors, including:

  • Square footage

  • House layout and design

  • Size and efficiency of windows

  • Insulation and air leakage levels

  • Climate

Why Is It Such a Big Deal to Have a Properly Sized Furnace?

Furnaces that are too big or too small can create different problems for your home comfort, and your wallet.

Is My Furnace Too Small?

If your furnace is undersized for your home, it will be running constantly to try to keep up with your home’s heating requirements. A heating system that’s running constantly will leave your searching for furnace repair near you much more often, will cost you more on your heating bills and will have a reduced lifespan.

Is My Furnace Too Big?

It’s easy to understand why an undersized furnace could be a problem in your home, but surely it couldn’t hurt if your furnace is too big, right? Not so fast! If your furnace is oversized, you will likely run into issues with your heating system “short cycling.” This refers to your system turning on and quickly too quickly, and just like a furnace that is constantly running, it will cause extra wear and tear, resulting in more service calls and a heating system that will need to be replaced sooner.
