A modulating furnace is the perfect gas furnace for our climate in the Willamette Valley. A modulating furnace has the ability to run at a very low heat setting, a high heat setting, or anywhere in between. By running at a lower heat setting the modulating furnace can use less gas and electricity to heat your home, and deliver a higher level of comfort. The heat setting that a modulating furnace operates at is determined by factors like outdoor temperature, and the set point of the thermostat. The colder it is outside, the more heat the furnace will need to put out to maintain the desired temperature in the home. On a more mild day, the furnace can run at a lower heat setting to achieve the desired indoor temperature. This ability to ramp up and down makes for a very comfortable home, because the furnace will not heat the home too fast under lighter operating conditions. How often do you find your furnace turning on and off? If it is happening constantly, that’s because it is putting too much heat into the home too rapidly. The set point of the thermostat is achieved before the home is able to be heated evenly. This makes for hot and cold spots in the home, causes excess wear and tear on the furnace, and costs you more money to heat your home. We also discussed the advantages of a two stage furnace in the post, What is a Two Stage Furnace?. The two stage furnace offers a lot of the same advantages as a modulating furnace, but the modulating furnace takes it to another level. It offers a greater range of operation, therefore a greater comfort level, and better energy efficiency. If you would like to learn more, feel free to Contact Us to set up a free comfort consultation.
