Factors to Consider When Choosing a New Furnace

Whether you’re buying a brand-new heating system for a new home or need to replace an old heating unit, buying a new furnace is an important decision. Choosing the right furnace for your home will not only keep you warm through the coldest months, but it will also ensure that you keep your heating bills to a minimum. But what constitutes the right furnace? Here are some factors to consider when choosing a new furnace for your home.

Fuel Source

First and foremost, you need to decide what type of fuel source your new furnace will run on. Natural gas is the dominant heating source today. It’s also widely available and relatively inexpensive. If you live in a rural area not served by natural gas lines, liquefied propane (LP) is another option. Heating oil and electricity are other options for new furnaces.


Finding the right size furnace is important for many reasons, the most important being that a furnace that is too big or too small for your home will use more fuel and thus cost more to run. In order to size a new furnace, match the heat output with the size of your home. Your Nashville heating company can help you select the right size furnace.


Another important factor is the efficiency of the furnace. All furnaces now carry Annual Fuel Utilization Efficiency (AFUE) ratings. A high-efficiency furnace will produce heat with 90 to 98 percent of the fuel. While you will pay more upfront for a high-efficiency furnace, you will dramatically lower your operating expenses.
