In cold-weather climates like Iowa’s, a furnace is often the most energy-efficient and affordable choice you can make when it comes to the comfort of your home.

We suggest paying attention to the Annual Fuel Utilization Efficiency, the rating that shows how much fuel you use to heat your home or business. If your furnace has an AFUE rating of 75%, it means that approximately 25% of the fuel you pay for through your energy bills is lost through system inefficiencies. All furnaces will lose a little heat, but Carrier® furnaces from Novak Heating and Cooling range between 80% and 98.5% AFUE.
