Have a licensed contractor evaluate your current system. Once the decision to replace your steam radiators with forced air is made, the complete boiler and pipe system must be removed.
Layout the duct design and cut holes in your floors and walls accordingly to accommodate your ducts and registers. Depending on your specific floor plan, you may have to sacrifice closet space and wall space as locations to route new duct work.
Install your furnace, including electrical, gas and exhaust per the furnace manufacturer instructions. Adding air conditioning or installing a heat pump in place of a furnace and air conditioner are available options.
- Replacing steam radiators with forced air has good and bad points. Being able to add central air conditioning is an advantage. A forced air furnace would also be more efficient than an older steam boiler. However, the electric fan and controls could increase your electric bill, offsetting the efficiency advantage in locations with higher electric costs.
