AC Replacement & Installation in Massachusetts: what's different
AC Replacement & Installation across Massachusetts depends on the climate (IECC climate zones 5).

Massachusetts licenses gas fitters, sheet metal workers and refrigeration technicians through state boards, and permits are issued by local building departments. Ask any contractor for their license number before work starts, and expect a written price for AC Replacement & Installation.
Eversource and National Grid are the main utilities for electricity and natural gas, with municipal utilities in some towns.
