What Size Furnace Do I Need?
When it comes to keeping your home warm and comfortable, one of the most important decisions you’ll make is choosing the right size furnace. A furnace that’s too small will struggle to keep your space warm, while one that’s too large can lead to wasted energy and uneven heating. So, how do you determine what size furnace you need? Understanding the process starts with knowing how to calculate furnace size using key factors like your home’s square footage, insulation, and local climate.

How Furnace Size Is Measured
Furnace size is typically measured in BTUs, or British Thermal Units. BTUs measure the amount of heat a furnace can produce, and the higher the BTU, the more heat it can generate. This is crucial for determining the right-sized furnace for your home. If you choose a furnace with a BTU rating that’s too low, it will have to work harder to heat your space, leading to higher energy bills. On the other hand, a furnace with too high a BTU can waste energy and cause inconsistent temperatures in your home.
Factors To Consider When Sizing a Furnace
When it comes to sizing a furnace, several factors come into play. It’s not just about your home’s square footage, though that’s certainly important.
Consider the following when sizing your furnace:
- Square footage: The larger your home, the more BTUs you’ll need. Larger spaces require more energy to heat.
- Ceiling height: Homes with higher ceilings will require a furnace with a higher capacity because there’s more air to heat.
- Home type: Older homes often need a larger furnace, especially if they have outdated insulation or drafty windows. If you have a more modern, well-insulated home, you might need a smaller furnace.
- Climate: The climate in your area will also affect furnace sizing. For colder climates, like those found in the Chicago area and the North Shore, you’ll need a furnace that can handle extreme temperatures.
Why Furnace Size Is Important
A new furnace is a long-term investment in your home. Most furnaces, with proper care, can last up to 20 years or more. Choosing the right size ensures that your furnace operates efficiently throughout its lifespan, avoiding costly repairs and unnecessary energy use. An improperly sized furnace may have to work harder, leading to premature wear and tear, or it could cycle on and off too frequently, causing uneven heating and discomfort.
How To Calculate Furnace Size
An HVAC load calculation considers factors like your home’s insulation, layout, and climate to provide the most accurate and tailored furnace size for optimal comfort and efficiency. However, to help you get a better idea of what size furnace you might need, here’s a general guide based on the size of your home:
- For a 1,200-square-foot home, you’ll need between 35,000 and 75,000 BTUs.
- For a 1,500-square-foot home, expect 45,000 to 90,000 BTUs.
- A 1,800-square-foot home requires 55,000 to 110,000 BTUs.
- A 2,000-square-foot home typically needs 60,000 to 125,000 BTUs.
- For a 2,400-square-foot home, you’ll want 75,000 to 145,000 BTUs.
