One disclosed furnace planning method

Plan $4,500–$10,500 for an installed 80k–100k BTU gas furnace, using $6,800 as the midpoint. Installed HomeScore planning range for an 80k–100k BTU gas furnace with professional labor, standard materials, startup and permit/inspection allowance. Major ductwork, asbestos or mold remediation, structural work and fuel conversion are outside the range.

Make furnace quotes comparable

  • Equipment make, model, input/output BTU and AFUE
  • Equipment price separated from labor and standard materials
  • Venting, condensate, gas-line, electrical, thermostat and duct changes itemized
  • Permit, inspection, disposal, startup and commissioning responsibility
  • Explicit exclusions plus a 10–15% homeowner contingency held outside the signed base bid

ENERGY STAR and DOE support the AFUE definition and efficiency comparison; they do not support HomeScore's dollar range.
