What the job involves
A furnace installation replaces the equipment that makes heat and sends it through your ducts. Many furnaces burn natural gas or propane, and others heat with electric elements, so the fuel decides which connections the installer has to make.
Furnace repair is a separate job: it fixes a failed part and leaves the furnace where it is. A heat pump installation is separate too, since a heat pump warms the house by moving heat in from outdoors. The work may need a permit from your city or county.
What's usually included
- Connecting the new furnace to the ducts, the thermostat and the power
- Connecting the gas line and the vent, for a gas furnace
- Firing up the furnace and confirming that it heats and shuts off normally
What moves the price
- Vent and drain
- A high-efficiency furnace usually vents through plastic pipe instead of the old metal flue, and it needs a drain for the water it makes. Rerouting the vent or adding a drain adds material and labor.
- Heat levels and fan speed
- Some furnaces heat at one level, and others run at more than one level or adjust in small steps. A variable-speed blower is a separate choice, and each step up usually costs more.
- The coil on top
- In many homes the air conditioner's indoor coil sits on the furnace. It has to be disconnected and reconnected, and sometimes replaced, which adds time to the job.
- Gas line
- The gas line may be too short, too small or in the wrong spot for the new furnace. Changing it adds pipe and labor.
- Moving the furnace
- Setting the new furnace in a different spot from the old one means new duct connections, a new vent path and possibly a new gas line.

- How many levels of heat does the furnace have, and is the fan variable speed?
- If my air conditioner's coil sits on the furnace, what happens to it?
- Does the price include a new thermostat, or will mine stay?
- Will you test the vent and the gas connections before you leave?
