Residential Heating Tip: Why Furnace Size Matters

Whether you are installing a new furnace or retrofitting your old heating system, you must get the proper size for your home and heating needs. There are several reasons for this. You can always call the Bolingbrook heating experts at DuAll Heating & Cooling if you would like a better understanding of furnace size and why it is important.

To get you started, here are a few of the main reasons that not properly sizing a furnace can end up costing you more in the long run, especially an oversized furnace.

We are focusing on oversized furnaces since this is the most common problem in our industry. Many contractors will try to talk you into getting a furnace that is too big for your heating needs. In addition, the size of your ductwork must be able to deliver the extra BTUs of heating output. If not, you may end up paying more to repair a furnace that has broken down due to constant cycling due to limit switch problems. Not only that, it could wear out the heat exchanger, which is a costly replacement.

The BTU capacity of your new furnace should depend on other factors as well, including the square footage of the space you need to heat and how many doors and windows are in your home. The location and layout will also play a role in the sizing process. Make sure your thermostats are up to date as well. For new high-efficiency furnaces, you’ll need to install a two – stage thermostat that can handle the variable speeds of the fan blower.

If you have further questions, call the Bolingbrook heating professionals at DuAll Heating & Cooling. We can answer all your questions and set up a consultation with a technician to assess your home and current heating system if you are interested in a furnace installation.
