What You Should Think About When Replacing Your Furnace

February 26, 2019

When it’s time to look for a new furnace, there are a number of things you should assess before making a decision on a particular replacement furnace. With your house and your family’s needs in mind, B & G HVAC can help you select the furnace that will keep your home warm and comfy.

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 run on 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 necessary 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 consistently at one speed and isn’t the strongest in efficiency amid 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 increase on the coldest Marshalltown days. However, if you want to go for the ultimate choice in flexibility and efficiency, a variable capacity furnace may be right for you.

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

Zoning
Whether you want to include a zoning system with your replacement furnace is another feature to discuss. You could save money 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 details about zoning possibilities for your home, B & G HVAC can help.

Size
Another key part of choosing the best furnace for your home is making sure it’s the correct size for your home. 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 Marshalltown days.

Efficiency
Last, but certainly not least, you need to check 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 gets out through places like the furnace venting. In order to have a high-efficiency furnace, make sure to find a system with an AFUE rating of 90 to 98.7 percent.
