Is a permit required to install a heat pump or air-conditioning unit?
A mechanical permit is required to erect, install, enlarge alter, repair, remove, convert, or replace a mechanical heating, ventilating and air-conditioning system. This includes, but is not limited to, furnaces, heat pumps, and ductwork. Homeowners cannot obtain permits associated with natural or propane gas or fuel oil piping and associated installation of fuel oil tanks. All gas work must be performed by a licensed Master Plumber or Gasfitter.
