Can Forsaire furnaces be used as a primary heating system?

Hello, thank you for reaching out. Yes, Williams Forsaire furnaces can be used as a primary heating system for many residential applications. They are commonly used as the main heat source in homes, cabins, apartments and other spaces where central HVAC systems cannot be installed. Although there are a few considerations: sizing is critical - the furnace must be properly sized based on the home's heating load, single-unit applications - smaller homes or open floor plans may use one Forsaire furnace as the primary heater, larger homes - multiple units may be required to provide even heating throughout the space, not a replacement for central HVAC in every application - homes that are needing extensive zoning, cooling integration or ducted air distribution may be better suited for a central system.
