What Size Furnace Do I Need?

Determining the Ideal Furnace Size for Your Home

“What size furnace do I need?” is among the most common heating questions we receive at Timothy Off. Most homeowners are aware that the size of a house dictates the size of the furnace which is needed. Beyond that, it is often unclear how to achieve the specific numbers, and that leads to uncertainty because an undersized or oversized furnace is going to end up costing you more in the end. This is why it so important to seek consultation from a heating expert who can provide you personalized advice.

If you live in Chester, Delaware or Montgomery counties in PA you can trust the NATE-certified HVAC technicians at Timothy Off. Contact us today for a free estimate to replace your furnace. We’ll thoroughly inspect your home and can provide recommendations on the perfect size.

Square Footage Is the Most Important Factor

The most important factor in determining what size furnace you need is the square footage of your home. If you are unsure how large your home is, you can find that information on closing documents or acquire it from documents that are on file with the township. In the event that the information is not available, it can be determined by breaking the home down into rectangles, measuring each and combining those values. Skip the guesswork and reach out to Timothy Off now for help!

BTUs and Square Footage

BTU is a unit of heat that a furnace produces. Most furnaces on the market are rated for 80,000 to 100,000 BTUs but heating equipment that produces less than and more than that range are available as well. The average home in the United States is 2,000 square feet. A home of that size will have an industry recommendation of 80,000 to 115,000 BTUs.

Climate Is a Factor Too

In the United States, a home will need 30 to 60 BTUs per square foot. To determine your specific number, you need to know the zone in which you are located. There are seven zones in all. Zone 1 is the hottest. Zone 7 is the coldest. Much of Pennsylvania is zone 5, which demands 50 BTUs per square feet. In our earlier example, you would need 50 BTUs x 2,000 square feet = 100,000 BTUs.

Insulation Is Another Factor

A modern home that is well sealed and well insulated will require less BTUs per square feet than an older home. Ideally, you want to conduct an energy audit and insulate the home as needed. But if you will invest in the furnace prior to that home improvement project, then you will want to size the furnace based on the current condition of the home.
