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 think about before making a judgement on a particular replacement furnace. With your home and your family’s needs in mind, Davis Heating & Air Conditioning can help you find the furnace that will keep your home warm and comfortable.

Fuel Source
One of the first factors you need to think about is which fuel source your new furnace will use. The majority of furnaces in North America utilize 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 necessary for your new furnace.

Furnace Type
You’ll also want to determine which type of furnace you’d prefer to successfully meet your needs. Furnaces are offered in single-stage, two-stage or variable capacity models. A single-stage furnace blows heat constantly at one speed and isn’t the strongest in efficiency among these options. A two-stage furnace works great for many homes. Stage one of a two-stage furnace operates at about 65 percent of its capacity, and stage two will kick in for a heating increase on the frigid Rocky Mount days. However, if you want to go for the best choice in flexibility and efficiency, a variable capacity furnace may be an ideal solution.

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

Zoning
Whether you want to factor in a zoning system with your replacement furnace is another feature to discuss. You could save on your energy bills by more efficiently using your furnace to heat the areas you normally use, rather than trying to keep the entire home at the same temperature. If you want more details about zoning options for your home, Davis Heating & Air Conditioning can help.

Size
Another important part of selecting the best furnace for your home is ensuring it’s the proper size for your home. If your furnace is too large for your home’s heating needs, it will waste a lot of energy incessantly cycling on and off. If your furnace is too small, it won’t be able to warm your home on the coldest Rocky Mount days.

Efficiency
Last, but certainly not least, you need to review your furnace’s energy efficiency rating. A furnace’s efficiency is determined 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 gets out through places like the furnace venting. A high-efficiency furnace will have an AFUE rating of 90 to 98.7 percent.

As you can see, there’s a lot to consider when searching for a replacement furnace. But, you’re not in this alone.
