What Is a Modulating Gas Furnace and How Does It Help?
An underperforming heating system can be caused by a clogged air filter or worn-out furnace parts. If your furnace has served you for decades, it may be time to consider a gas furnace replacement. Since modern furnaces offer much higher energy efficiency, you might want to act sooner.

In addition to an efficiency boost for modern furnaces that raises you from around 60 percent to over 80, new technologies like modulating furnaces help you go further. They provide variable heating capacity instead of the on or off operation of traditional single-stage furnaces, for more refined heating operation.
Let us familiarize you with modern gas furnace replacement models, and help you compare AFUE ratings, make BTU heating load calculations for your home, and plan expert installation. Our Environmental Heating & Air Solutions technicians are NATE-certified, and we have BPI-certified professionals to help you maximize your comfort in Antioch.
