Furnace Sizing for Your St. Louis Area Home: How It’s Done Right and Why It Matters

small_5094688060One of the most important aspects of a furnace installation is that the right sized system is selected for your home. This requires a detailed analysis of your home that will allow us to choose a furnace that’s not too big and not too small, but rather the perfect size for your home’s specifications. Today we’re going to talk about why proper furnace sizing is so important and some of the main factors we at Jerry Kelly take into account when selecting the right furnace size for our customers!

Why is proper furnace sizing important?

In order to have the most comfortable and efficient home possible, it’s essential that your furnace’s size matches your home’s specific heating requirements.

If your furnace is too small for your home, your system won’t be powerful enough to provide the required amount of heat. This will force your furnace to work nearly non-stop (which will be a drain on your energy bills) without ever actually making your home as comfortable as you’d like it to be.

If your furnace is too large for your home, it will be able to meet your home’s heating requirements but it will do so too fast. As a result, your furnace will cycle on-and-off frequently, which often leads to large temperature swings, high energy bills and an increased likelihood of your system breaking down.

What goes into proper furnace sizing?

The best way to ensure that you choose the right-sized furnace for your home is to work with a trusted heating contractor like Jerry Kelly for your installation. We use an industry-standard “load calculation” to figure out your home’s specific heating requirements. This calculation takes a number of different factors into account, including:

  • Your home’s square footage
  • Shape and orientation of your home
  • Amount of windowsin your home and where they are located
  • Insulation levels
  • Air infiltration rates
  • Amount of people living in your home
  • Number of heat-emitting appliances

After gathering data on all of the above factors (and more), we can calculate your home’s precise heating load and use that information to choose the right furnace size.

If you have any questions about proper furnace sizing, or if you’d like a heating system serviced or installed in your home, contact Jerry Kelly, your St. Louis heating and cooling contractor. We service the St. Louis area, including towns like Ballwin, Chesterfield and Clarkson Valley.
