Furnace vs Boiler in Fresno County, California
When a furnace makes sense
If your house already has ducts, a furnace is the simpler path, and just over half the homes in this region do. It heats the whole house through the vents already there, and with winter nights averaging 32°F from December through February, you want a system that pushes heat out fast when you need it. Gas furnaces recover a room's temperature quickly, which matters over eight months of heating.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler is the natural fit, since there is no ductwork to add. It also runs about 5% cheaper to operate here than a furnace, which adds up over eight months of heating. Boilers suit homes already built around that kind of heat, so check what your house has before ruling one out.
