Counting the Basement in Furnace Sizing

Whether to count the basement when sizing a furnace depends on whether it’s a livable space that requires heating. If you plan to heat your basement, include its square footage in your calculations.

If the basement is finished or will be used as a living area, heating is important for comfort and to prevent issues like pipes freezing. However, if the basement is unfinished and you don’t plan to heat it, you don’t need to include its size when sizing your furnace.

 Always consider your specific needs and how you’ll use the space when deciding.

  1. Garage Furnace Sizing

For garages, sizing depends on their use (storage vs. workshop) and insulation. Typically, a smaller unit suffices unless the garage is used as a workspace or has poor insulation.

  • Gas Furnace Sizing

Gas furnaces are commonly sized using the same principles but may have specific efficiency ratings (AFUE). A high-efficiency gas furnace might require slightly different sizing compared to a standard unit.

Sizing a Furnace for a House

Electric furnaces are sized similarly to gas furnaces but consider electrical requirements and efficiency. Ensure your home’s electrical system can support the furnace’s power needs.

 To size a furnace for your house:

  1. Calculate Total Square Footage: Include all heated areas.
  2. Determine BTU Requirements: Use climate zone and insulation quality.
  3. Select the Furnace: Choose a furnace with the closest BTU output.

Annual Furnace Maintenance

Regular maintenance is essential to keep your furnace running efficiently. For gas furnaces annual maintenance, includes checking the gas lines, burner, and heat exchanger for leaks or damage. It’s crucial for safety and efficiency.

Annual maintenance typically includes:

  • Inspecting and cleaning the furnace
  • Checking and replacing filters
  • Ensuring proper ventilation
  • Testing the thermostat

The annual furnace maintenance cost varies but generally ranges from $75 to $200. This cost can be higher if repairs or parts replacement are needed.

Do Gas Furnaces Require Annual Maintenance?

Yes, gas furnaces need yearly maintenance. This keeps them running safely. A technician will clean and check the furnace, making sure everything is working well. This can prevent dangerous problems like gas leaks and can help the furnace last longer.

If you skip annual maintenance, your furnace might not work as well, which can raise your energy bills. It could also break down unexpectedly, costing a lot to fix. Regular check-ups catch small problems early, so your furnace works when you need it most, especially in the winter.


Proper furnace size and regular maintenance are important for keeping your home warm and safe. Use tools like furnace size calculators and charts to determine the right size for your home, and don’t skip on annual maintenance to ensure your furnace operates efficiently year-round.
