Understanding How Modulating Gas Furnaces Work

Around 46% of your electricity bill is from heating and air conditioning your home. Because of this, it is important to find the most efficient furnace possible. Depending on your home, modulating gas furnaces could be the best option for keeping your Winnetka, IL house warm in wintertime.

What Is a Modulating Gas Furnace?

A modulating gas furnace uses a secondary heat exchanger, variable speed control, and a modulating gas valve. The secondary heat exchanger sends extra heat from combustion to the primary heat exchanger, which helps to reduce the amount of wasted heat. Meanwhile, the modulating gas valve helps the furnace maintain a consistent temperature. Finally, the variable speed control allows the furnace to work at a lower capacity when it needs to.

All of these benefits are the reason why modulating gas furnaces tend to operate at a lower cost. They provide a high level of comfort and make less noise when they are operating than a single-stage furnace. While you still need to in routine maintenance tasks to keep your furnace operating well, this type of furnace should last for at least 15 to 20 years.

The Inner Workings of a Modulating Gas Furnace

After you hire someone for professional installation services, you can begin using your modulating gas furnace. With this kind of furnace, a gas valve and blower fan are constantly adjusting their operation level so that your home can maintain the right temperature. In comparison, a single-stage furnace runs at full capacity all the time. Once it reaches the right temperature, it turns off.

Meanwhile, a two-stage furnace has different settings. This means there are fewer temperature swings. However, two-stage furnaces will still spend more time turning off and on than modulating gas furnaces
