What You Should Think About When Replacing Your Furnace

February 26, 2019

When it’s time to get a new furnace, there are several things you should consider before making a decision on a particular replacement furnace. With your house and your family’s needs in mind, WM J Kraus & Son can help you choose the furnace that will keep your home warm and comfy.

Fuel Source
One of the first aspects 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 homes are set up to use liquified petroleum gas, propane or even electricity. It’s critical 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 successfully meet your needs. Furnaces are offered 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 among these options. A two-stage furnace is a good fit for many homes. Stage one of a two-stage furnace works at about 65 percent of its capacity, and stage two will kick in for a heating blast on the frigid Keokuk days. However, if you want to go for the greatest 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 create heat. A variable capacity furnace can actually operate at different capacities to answer your heating needs.

Zoning
Whether you want to include 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 typically use, rather than trying to keep the whole house at the same temperature. If you want more information about zoning solutions for your home, WM J Kraus & Son can help.

Size
Another key part of choosing the best furnace for your home is making sure it’s the right size for your space. 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 Keokuk 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 signifies 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 escapes 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.

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