- Adding or replacing built-in heating equipment (furnaces, heat pumps, boilers, ductwork and radiators) in homes whose main heating equipment is a steam or hot-water system (boiler).
Not counted:
- Thermostats.
- Room air conditioners.
- Repairs and tune-ups that did not add or replace equipment.
The survey records the home's main heating equipment, not the unit that was put in.
Survey category: "Added or replaced built-in heating equipment". Costs the Census Bureau filled in (9% of the professional jobs) are left out.
