If you’re replacing your heating system, you might be wondering whether to stick with what you have or consider switching. Boilers and furnaces both do the same job — they heat your home — but they do it in completely different ways, and each has advantages depending on your home’s setup.
Furnaces use forced air. They heat air and push it through ducts to vents in each room. They’re common in newer construction and can also handle central air conditioning through the same duct system, which makes them convenient. The downside is that forced air systems can feel drafty, they distribute dust and allergens through the ducts, and they require filter maintenance to keep airflow unrestricted.
Boilers use hot water or steam. The water is heated and circulated through pipes to radiators or baseboard units, which radiate heat into each room. This type of heat tends to feel more even and comfortable — there’s no air blowing, no ducts to clean. Boilers are also generally better for air quality since they don’t circulate air throughout the house.
The practical question is usually about what your home already has. If your home has ductwork, a furnace replacement is straightforward. If your home has radiators and pipes, switching to a furnace would require installing ductwork throughout — a major renovation that often isn’t worth the cost. In most cases, the right choice is to stay with what you have and upgrade the equipment.
