Heating and Cooling
Is it time to replace your furnace or air conditioner? A variety of new equipment options can offer you increased comfort and cut your heating bill.
- Older furnaces are frequently around 60% Annual Fuel Utilization Efficiency (AFUE).
- Older furnaces waste 40 cents of every heating dollar.
- A 90% AFUE furnace saves about one-third of your heating costs.
- An 80% AFUE furnace saves about one-fourth of your heating costs.

Estimated annual savings from improved furnace efficiency assumes existing furnace efficiency of 60%.
Note: If you have natural gas appliances such as a water heater, dryer or stove, be sure to subtract that use when calculating your home heating costs. Your summer gas use is a fair approximation of your nonhome heating gas use.
For example, if your average summer gas use costs $14 per month, multiply this by 12 to find your nonheating gas use for the year.
Subtract this amount from your total 12-month gas bill to find your annual heating cost.
My Energy Use
$14/month x 12 months = $168 non-home heating gas use
Total gas use for the year = $750
$750 - $168 = $582 annual heating cost
