What You Should Think About When Replacing Your Furnace

February 26, 2019

When it’s time to look for a new furnace, there are several things you should think about before making a decision on a particular replacement furnace. With your house and your family’s needs in mind, Clean Air HVAC can help you find the furnace that will keep your home warm and cozy.

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

Furnace Type
You’ll also want to determine which type of furnace you’d prefer to successfully meet your needs. Furnaces are available in single-stage, two-stage or variable capacity models. A single-stage furnace blows heat constantly at one speed and isn’t the strongest in efficiency within these options. A two-stage furnace works well 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 Pacheco days. However, if you want to go for the best choice in flexibility and efficiency, a variable capacity furnace may be a good option.

Unlike single- and two-stage models, variable capacity furnaces don’t have a certain number of stages to go through to provide 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 thing to think about. You could save money by more efficiently using your furnace to heat the areas you regularly use, rather than trying to keep the whole house at the same temperature. If you want more to know more about zoning solutions for your home, Clean Air HVAC can help.

Size
Another critical part of picking the best furnace for your home is confirming 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 provide adequate heat on the coldest Pacheco days.

Efficiency
Last, but certainly not least, you need to review 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. For a high-efficiency furnace, you’ll want to look for an AFUE rating of 90 to 98.7 percent.
