AFUE Ratings: What They Are And Why They Matter When You’re Buying A Furnace


When you’re in the market for any type of new appliance, you always want to make the most informed decision possible. Buying a new furnace is no exception. The energy efficiency of any potential heating system is something you’ll want to keep in mind, and AFUE ratings are an easy way of measuring this. It means annual fuel utilization efficiency, and it’s used to measure how well a furnace or boiler converts energy it uses into heat. As an example, if a furnace has an AFUE rating of 95 percent, that means it successfully turns 95 percent of the energy it uses into heat, while that last little 5 percent goes to waste.

There are several reasons why AFUE ratings are so important to consider. First of all, appliances that waste less energy are simply better for the environment. Aside from that, they have the potential to save you a lot of money down the road. As recently as 10 or 15 years ago, new furnaces and boilers were wasting a lot more energy than current ones do, and even though you aren’t getting any heat from that energy, you still end up paying for it when the heating bills come around. To illustrate how big the difference is, if you were to upgrade from a 75 percent AFUE rated furnace, all the way up to a newer, 95 percent rated one, you would immediately begin saving that 20 percent different on utility bills, according to some sources.

Unfortunately, these new heating systems can run you $4,000 to $6,000, meaning many households simply can’t afford to make the investment. However, if it’s something you can afford, then you would be wise to go out and make that upgrade now. It may seem like a big dent in your wallet in the present, but it’s guaranteed to pay off in the long run.

So, don’t overlook those AFUE ratings when shopping for a new furnace. It may not seem important now, but it will make a big difference down the road. For household needs in the Portland, Ore., area, contact the professionals at Roth Heating & Cooling, Plumbing, Electrical, Drain Services.
