What Furnace Installation Includes
A new furnace installation includes an on-site load assessment, equipment selection matched to the building's heating demand, removal of the old unit, installation of the new furnace, venting and gas connection work, electrical connection, thermostat setup, and start-up testing.
Permit requirements vary by municipality. The installation follows local code for gas piping, venting, and electrical work.
Furnace Sizing and Selection
Correct sizing depends on the building's square footage, insulation, window area, ceiling height, and the local climate. An oversized furnace short-cycles and wastes energy; an undersized furnace cannot maintain temperature during cold snaps.
A technician performs a load calculation on site rather than relying on the old unit's capacity. Equipment efficiency, measured in AFUE, affects long-term operating cost. See our AFUE explainer for what that rating means.
