Understand your options

A simple scope statement could be: “Design, install, and commission a heat pump system to replace my existing RTU(s) OR either fully or partially replace my existing furnace and AC (if it exists) by [indicate target end date].”

A more detailed scope might be helpful if you have other requirements – like needing construction to occur on weekends, adding a humidifier, or relocating ductwork.

• Equipment life expectancy (as determined in Stop 2).

• Install equipment in Spring or Fall to avoid heating or cooling disruption during extreme weather.

• Coordinate with other renovations. For example, if you are having work done on your roof, consider finishing that before installing new rooftop heat pumps.

• Install equipment to minimize occupant disruption (particularly if you rent your building and expect to have a period of vacancy between tenants).

• Build in time to budget and access funding.
