Furnace vs Boiler in Adams County, Colorado
When a furnace makes sense
If your house already has ductwork, a furnace is the simpler choice. Most homes in this region are set up this way, and that same ductwork can carry air conditioning later without any extra work. With eight months of heating season and nights averaging 16°F, you want equipment that matches what's already in your walls.
When a boiler makes sense
A boiler makes sense if your home heats through radiators or in-floor pipes rather than ducts. It runs about 5% cheaper than a furnace at Colorado prices, which adds up over eight months of heating season. It won't help with cooling, since it only heats, but if your house has no ducts to begin with, that's not a loss.
