Central Gas Furnace Heating Costs

Indoor Cost Guides Air-Conditioning & Heating (HVAC) Central Gas Furnace Heating Costs

The domestic central-furnace forces heated air through ducts to heated zones of the house.

Sizing the furnace per area of heated zones depends primarily on the regional climate assuming that house insulation properties are adequate. In the colder regions about 70 BTU per hour (BTU/h) are required per square foot of heating zone, in the warmer regions about 35 BTU/h are required per square foot.

The cost to install average gas central-furnace heating depends upon type, heating capacity, heating distribution, preparation and special needs, and the labor rate.
