How to Determine the Right Size Furnace For Your Home

Winters in Crown Point, Indiana and the surrounding areas are very cold and windy. When you’re at home, you want to be cozy and comfortable. Of course, the key component in your overall comfort when it’s cold outside is your furnace. Your heating and air conditioning system is probably the most valuable resource within your home, both for what it provides and the cost to purchase and operate it. That’s why it’s important to determine the right size furnace for your home before you go ahead and pick any furnace.

It’s very important that the furnace installed is the right size for your structure. We’re not talking about the outside dimensions, though. When HVAC experts determine the correct size furnace, the key factor used is the total square footage of your living space or simply put, all the areas you want heated. 

Other important elements are the climate in which you live, the amount of insulation in your home, the number of windows, the number of floors, how much exposure your home has to the sun, overall interior layout, and more. 

As you can see, it’s a lot more complicated than pointing to a picture in a catalog. If you’re considering a furnace replacement, Merts Heating & Air Conditioning has trained Comfort Specialists available to assess your home and provide options to make a new furnace installation easy and efficient. 


It can be easy to assume that bigger must be better when it comes to furnaces. Having the wrong size furnace, though, can cause several issues with maintaining the level of warmth you desire, such as:

  • You’ll likely have hot and cold spots in your home because your system is short-cycling.
  • The frequent turning off and on makes for inefficient operation – wasting energy and your money.
  • When the furnace is running in short bursts and turning off prematurely, components can eventually break down, thus shortening the furnace’s lifespan.
  • The added wear on the furnace will lead to frequent repairs and more out of pocket expenses for you.
