Furnace Replacement 101: What Does System Tonnage Mean?

by | Dec 3, 2019 | Blog

While the daytime temperature in Kyle, Texas, is mild and pleasant, the night temperatures have dropped into the 40s. As a result, you’ve likely started using your furnace. But if your furnace isn’t turning on or blowing warm air, you might need to replace it. Read on to learn the importance of system tonnage when getting a furnace replacement.

Importance of the Right Furnace Tonnage

Sizing is a vital part of the furnace replacement process. A furnace that’s too large for your home will heat it too quickly and unevenly. It’ll cycle on and off often, which will increase wear and tear and reduce energy efficiency.

A furnace that’s too small for your home will operate continually without heating your home to your ideal comfort level. As a result, it’ll waste energy, strain itself and eventually break down. Furnace sizing is critical for correct operation.

How to Calculate the Furnace Tonnage

You’ll find furnaces measured in either British Thermal Units (BTUs) or tons. One ton equals 12,000 BTUs. Once you know how many BTUs you need to heat your home effectively, you can calculate the tonnage easily.

  1. Measure the square footage of every room and hallway in your house.
  2. Add your findings to determine your house’s total square footage.
  3. Multiple the total square footage by 35 to determine the BTU capacity your furnace needs.
  4. Divide the result by 12,000 to figure out the tonnage requirement for the furnace.
