What To Consider Before Buying a New Furnace

In a previous blog post, we discussed signs that it’s time to replace your furnace. Once you’re determined that you need a new furnace, how do you decide what model would be best for your home? Before committing to a particular model of furnace, it’s important to consider the specific heating needs of your home. Here are some things to consider when purchasing a new furnace.


Furnaces come in a range of sizes, and the size of your furnace will influence how it keeps your home heated. If you choose a furnace that’s too small, your unit may not have the capacity required to heat your entire home. However, a furnace that is too big may take up a disproportionately large area of your home. Furnaces that are too large can also be energy-wasters and cause your heating bills to skyrocket, and they also require larger air ducts that may be difficult to install in your home. Before purchasing a new furnace, consult with a professional HVAC technician to determine the appropriate furnace size for your home.

Energy Efficiency

Another concern that has become more important in recent years with regards to furnaces is energy efficiency. Energy-efficient units are better for the environment, and they can also help youth reduce your heating bill. The Annual Fuel Utilization Efficiency (AFUE) Rating is a scale that rates a furnace’s ability to efficiently turn gas into heat. This rating is measured as a percentage—the higher the percentage, the more energy-efficient the furnace.

Furnaces have come a long way in term of energy-efficiency—in the 1970s, the average furnace had a AFUE rating of 65%, and nowadays some models can reach an AFUE rating as high as 97%. A furnace with a high AFUE rating more be more expensive than a model with a lower rating, but it’s worth the investment—these high-efficiency models tend to have longer lifespans and generate lower heating costs, saving you money in the long run.
