Gas Furnace Heating Costs

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

The domestic gas furnace provides for heating interior spaces, and always requires a gas-vent to the exterior.

Sizing the furnace per area of heated zones depends primarily on the regional climate assuming that house insulation properties are adequate. In the coldest 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 furnace heating depends upon type, heating capacity, preparation and special needs, and the labor rate.
