What You Should Think About When Replacing Your Furnace

When it’s time to get a new furnace, there are a number of things you should assess before making a decision on a particular replacement furnace. With your space and your family’s needs in mind, Olde Towne Heating & Air can help you choose 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 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 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 blast on the chilly Mount Pleasant days. However, if you want to go for the best choice in flexibility and efficiency, a variable capacity furnace may be right for you.

In contrast to single- and two-stage models, variable capacity furnaces don’t have a certain number of stages to go through to create heat. A variable capacity furnace can actually work 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 every room at the same temperature. If you want more to know more about zoning options for your home, Olde Towne Heating & Air can help.

Size
Another key part of picking the best furnace for your home is ensuring it’s the right size for your house. 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 keep up on the coldest Mount Pleasant days.

Efficiency
Last, but certainly not least, you need to check your furnace’s energy efficiency rating. A furnace’s efficiency is calculated 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. A high-efficiency furnace will have an AFUE rating of 90 to 98.7 percent.
