With a climate like that of Northeast Ohio, furnace efficiency is important. Whether you’re choosing a new furnace or simply evaluating the efficiency of an existing model, a few factors should always be considered when talking furnace efficiency.
Annual Fuel Utilization Efficiency (AFUE)
The AFUE of your furnace indicates the level of efficiency with which you can expect fuel to be converted to useable heat. In other words, if your current furnace has an AFUE of 80 percent, 20 percent of your fuel’s heat energy is being wasted. Upgrading to a system with a 90 percent AFUE will cut that waste in half.
Before installing a furnace in your home, a trained technician will first perform a proper load calculation to determine the necessary heating capacity of your furnace. Furnace efficiency depends on this load calculation being accurate. If it isn’t, you could end up with a furnace that is either too small to handle the load, or too large to run in an efficient manner.
In fact, several things can go wrong with an over-sized system. Improper system cycling leads to unnecessary strain on your system. As a result, your system’s life is decreased, the need for repairs becomes more frequent, and your energy costs may rise dramatically.
Even a properly sized system with a furnace efficiency of 97 percent will underperform if not given proper care. To keep your furnace in tip-top condition, you should have it serviced annually. In addition to routine professional maintenance, there are things you can do to care for your system in the interim. For example, one of the easiest tasks you can perform to maintain furnace efficiency is to regularly change your filters. Depending on the unique demands of your household, filter changes may be necessary monthly, or as little as once every six months.
