If your heating system is not performing efficiently—especially if it is more than a decade old—replacing it with a new Energy Star rated high-efficiency unit will reduce your environmental impact and save money. Households in the United States are said to spend nearly 40 percent of their energy dollars on heating and cooling alone.
Heating systems have something called an Annual Fuel Utilization Efficiency Rating (AFUE). You’ll want something with an 80 percent AFUE minimum, though some warm-air furnaces go as high as 90 or even 97 percent AFUE. The higher you go, the greater the eco-impact and monetary savings.
A new high-efficiency heating system is only as effective as the energy efficiency of your home. Make sure to you have adequate insulation and air sealing before you go out and buy a new system. Simple cost effective measures done now may keep you from having to purchase anything new.
Have an experienced contractor come to your home to give you an analysis of what options are available to you, based on your current heating system and source.
After you install a new high-efficiency heating system, make sure to maintain it regularly for best performance.
