Gas Furnace Installation Cost
Reviewed by WattCostLab Editorial Team
Gas furnace project cost depends on capacity, efficiency, venting, duct condition, gas work, controls and local code requirements.
Efficiency can change venting requirements
High-efficiency condensing furnaces may require different venting and condensate handling than older non-condensing equipment.
Do not compare equipment price alone
Labor, venting, gas piping, electrical work, controls and duct corrections can materially change project scope.
Compare operating cost with alternatives
Fuel prices and heat-pump seasonal performance determine whether a heat pump or gas furnace is less expensive to operate in a particular home.
