What You Should Think About When Replacing Your Furnace

February 26, 2019

When it’s time to replace your furnace, there are several things you should think about before making a conclusion on a particular replacement furnace. With your home and your family’s needs in mind, Street Heating and Cooling can help you choose the furnace that will keep your home warm and cozy.

Fuel Source
One of the first factors you need to decide is which fuel source your new furnace will use. The majority of furnaces in North America utilize natural gas, but some residences 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 are available in single-stage, two-stage or variable capacity models. A single-stage furnace blows heat consistently at one speed and isn’t the strongest in efficiency amid these options. A two-stage furnace works great 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 increase on the frigid Rapid City days. Though if you want to go for the ultimate choice in flexibility and efficiency, a variable capacity furnace may be an ideal solution.

Unlike 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 reach your heating needs.

Zoning
Whether you want to include a zoning system with your replacement furnace is another thing to think about. You could save costs by more efficiently using your furnace to heat the areas you typically use, rather than trying to keep the entire home at the same temperature. If you want more details about zoning options for your home, Street Heating and Cooling can help.

Size
Another critical part of choosing the best furnace for your home is confirming 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 keep up on the coldest Rapid City days.

Efficiency
Last, but certainly not least, you need to review your furnace’s energy efficiency rating. A furnace’s efficiency is calculated 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.
