A little over a year ago, the original furnace in my house failed.
- Since the heater was well over twenty years old, parts were no longer available to make repairs.
The contractor who I’d hired assured me that a new furnace would pay for itself in savings on my utility bills. He told me that my house would feel more comfortable, stay cleaner and use less energy. I was still unhappy with the idea of the installation process and expense. A new furnace is pricey and I expected a great deal of disruption and debris. Once I started looking into the heating options on the market, I got a little more excited. I hadn’t realized the advances made in heating technology in recent years. My former furnace was a single-stage model, meaning that it could only operate at maximum capacity. It would run at its highest speed until it achieved the thermostat setting and then shut down. Once the temperature in the home dropped, the heater would start up again. This on and off operation creates temperature fluctuation and uses quite a bit of energy. Today’s furnaces feature adaptable-speed capabilities. The system is able to adjust capacity in one percent increments anywhere between 40 and 100%. There is rarely a time that the furnace needs to run at max speed. By automatically catering to the requirements of the home, the heater maintains a very consistent temperature at all times. It only supplies the exact amount of heat necessary. Because of this, modern furnaces achieve up to 98% AFUE ratings, make far less noise and don’t cause as big of problems with overly dry air. I was also able to take advantage of zone control to further cut running costs and improve comfort.
