Installation day starts before the old furnace is disconnected. Confirm the access route, protected work area, shutdown plan and scope for removal with the installer.
Prepare the equipment path
Clear belongings from the agreed work area and the path between the entrance and equipment room. Ask which doors or floor surfaces need protection. Keep children and pets away from the work zone.
Confirm what will change
Review the proposal with the installer before work starts. Identify the equipment being removed, components being retained and any work assigned to another trade. Ask when heat will be unavailable and how unexpected conditions will be handled.
Walk the finished installation
Have the installer show the filter path, service panels and thermostat operation. Ask where model information and installation documents are stored. Review the new venting, drain and visible duct transitions against the written scope.
ENERGY STAR quality-installation guidance tells homeowners to ask about home-specific sizing and manufacturer airflow. If the furnace is paired with cooling, the startup discussion should also address the matched equipment and controls.
