If Furnace Repair Isn’t Possible, Here Are Some Things to Consider When Buying a New One

Posted on: August 7, 2012

A good HVAC technician can handle most any furnace repair and will do his/her best to repair your furnace. However, if your technician tells you that your furnace is beyond repair, there are quite a few factors to consider when selecting a new one. Firstly, how much heating capacity does your home need? If you buy a furnace that’s too small, you won’t get enough heat on cold days. And, if you buy one that’s too big, it will generate more heat than you need, and your energy costs will escalate.

Energy Efficiency Rating

Today, furnaces are rated with the Annual Fuel Utilization Efficiency (AFUE) system which calculates how much energy a furnace converts into usable heat. For example, if a furnace is rated at 85 percent, it will convert 85 percent of the gas it consumes into heat. Presently, the lowest rating on a furnace is 80 percent.

But, if you want to buy a top-of-the-line furnace, some ultra-efficient gas models carry ratings as high as 98 percent. The higher the rating, the more expensive the upfront costs are, but in the long term, the savings are greater.
