What You Should Think About When Replacing Your Furnace

When it’s time to look for a new furnace, there are a number of things you should consider before making a judgement on a particular replacement furnace. With your house and your family’s needs in mind, US Air Heating and Cooling can help you select the furnace that will keep your home warm and comfy.

Fuel Source
One of the first things you need to decide is which fuel source your new furnace will use. The majority of furnaces in North America run on natural gas, but some homes are set up to use liquified petroleum gas, propane or even electricity. It’s important to know which type of fuel is needed for your new furnace.

Furnace Type
You’ll also want to determine 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 within 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 boost on the frigid Rock Hill days. But 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 create heat. A variable capacity furnace can actually work 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 normally use, rather than trying to keep every room at the same temperature. If you want more information about zoning possibilities for your home, US Air Heating and Cooling can help.

Size
Another important part of selecting the best furnace for your home is ensuring it’s the proper 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 warm your home on the coldest Rock Hill 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 represents 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. In order to have a high-efficiency furnace, make sure to find a system with an AFUE rating of 90 to 98.7 percent.
