What You Should Think About When Replacing Your Furnace

February 26, 2019

When it’s time to look for a new furnace, there are several things you should consider before making a decision on a particular replacement furnace. With your space and your family’s needs in mind, Southern Heating & Cooling Inc. can help you select the furnace that will keep your home warm and cozy.

Fuel Source
One of the first things you need to consider is which fuel source your new furnace will use. The majority of furnaces in North America use natural gas, but some houses are set up to use liquified petroleum gas, propane or even electricity. It’s vital to know which type of fuel is needed for your new furnace.

Furnace Type
You’ll also want to consider which type of furnace you’d prefer to effectively meet your needs. Furnaces come in single-stage, two-stage or variable capacity models. A single-stage furnace blows heat continually at one speed and isn’t the strongest in efficiency amid these options. A two-stage furnace works well for many homes. Stage one of a two-stage furnace runs at about 65 percent of its capacity, and stage two will kick in for a heating boost on the chilly Scottsboro days. Though if you want to go for the greatest choice in flexibility and efficiency, a variable capacity furnace may be a good option.

Different from single- and two-stage models, variable capacity furnaces don’t have a set number of stages to go through to provide heat. A variable capacity furnace can actually work at different capacities to meet your heating needs.

Zoning
Whether you want to incorporate a zoning system with your replacement furnace is another thing to think about. You could save money by more efficiently using your furnace to heat the areas you typically use, rather than trying to keep every room at the same temperature. If you want more to know more about zoning options for your home, Southern Heating & Cooling Inc. can help.

Size
Another critical part of choosing the best furnace for your home is ensuring it’s the correct size for your space. If your furnace is too large for your home’s heating needs, it will waste a lot of energy constantly cycling on and off. If your furnace is too small, it won’t be able to provide adequate heat on the coldest Scottsboro days.

Efficiency
Last, but certainly not least, you need to consider your furnace’s energy efficiency rating. A furnace’s efficiency is measured by annual fuel utilization efficiency (AFUE). This rating identifies the ratio of annual heat output of the furnace compared to the total annual fossil fuel energy it consumes. For example, an 80 percent AFUE rating means that 80 percent of energy in the fuel heats the home and the other 20 percent is lost through places like the furnace venting. For a high-efficiency furnace, you’ll want to look for an AFUE rating of 90 to 98.7 percent.
