The routine when replacing a furnace is, roughly, as follows. The gas lines, plumbing, refrigerant lines and electrical are detached, capped and protected, as required. The ductwork is detached from the old unit. The old central heater is removed. Getting a heating system from a heater closet is often more difficult than expected. The installer will carry the old unit away, and most likely recycle it. The heater area is then cleaned and readied to receive the fresh unit.
Before installation of the new system, the ductwork will likely have to be modified to fit. Once the new unit is in place, and the ductwork, the plumbing, electrical wiring and gas and refrigerant lines are all properly connected, the gas lines and the HVAC system is tested. The specialist will also run the furnace and inspect for carbon monoxide gas, a hazardous combustion by-product that can pass in to the heated air if the unit is deficient or the installation is performed improperly. The thermostat may also need to be replaced, programmed and tested.
