AC Replacement & Installation in Maine: what's different
AC Replacement & Installation across Maine depends on the climate (IECC climate zones 6–7). Air conditioning runs only a few months a year in very cold climates, so many systems are older or lightly used. When summer heat arrives, failures usually trace back to parts that degraded while sitting idle.
In Maine specifically: extreme cold. Backup heat and frozen-pipe prevention are important.
Maine licenses oil and solid fuel burner technicians and propane and natural gas technicians through state boards; heat pump installers may need related licenses. Ask any contractor for their license number before work starts, and expect a written price for AC Replacement & Installation.
Central Maine Power and Versant Power are the main electric utilities. Summit Natural Gas and Maine Natural Gas serve limited areas.
Maine climate
Very cold climate, IECC climate zones 6–7. Oil boilers and furnaces remain common, along with propane and wood. Ductless cold-climate heat pumps are widely installed to reduce oil use and add summer cooling.

In most places, yes. Equipment replacement usually requires a mechanical permit from your city or county, and the contractor normally pulls it.
