When it comes time to get a new furnace, it’s very important to get one that’s the right size. One that’s not the right size will cost you money and make your home less comfortable.

Heat Factor

Furnaces are measured in British Thermal Units (BTUs). You need a furnace with more BTUs in parts of the country that get freezing in the winter, such as the Midwest. In an area like Southern California, you don’t need as powerful of a furnace.

Basic Heating Need

To find your basic heating need, multiply the square footage of your house with the heating factor for your part of the country. If you own a 2,400-square-foot property in the Midwest, you’ll need an 84,000 BTU furnace. In Southern California, that same size house would need just a 36,000 BTU furnace.

There are other variables to consider, too. If your home is well-insulated, you can purchase a furnace with fewer BTUs. The amount of glass in your residence is also important, as houses with a lot of glass need a stronger furnace than they otherwise would.

Beware of an Oversized Furnace

You may be tempted to get a furnace with more BTU than you need. This would be a big mistake, as your home won’t be comfortable. The furnace will short-cycle, which means it quickly turns on and off. It will also have a reduced lifespan and the heat exchanger will probably crack.

Don’t Choose an Undersized Furnace

An undersized furnace also isn’t desirable. It will struggle to heat your home to your desired temperature. It will drive up your energy bills since it will run constantly. Like an oversized furnace, its lifespan will be much shorter than it should be.
