About This Market
Boston's HVAC market runs hot and cold - literally. You've got 685,000+ residents dealing with brutal winters and muggy summers, plus constant construction feeding commercial demand. Old housing stock means retrofit jobs and emergency calls dominate residential work. Competition is fierce with 3,034 licensed establishments statewide, but demand stays strong year-round. Costs run 10-15% above national average due to high labor costs, tight jobsites, and permit requirements.
To work Boston, get your CSL license first - no shortcuts. The exam's tough and the 3-year experience requirement is enforced. Learn Boston's permit system inside out, because ISD doesn't mess around. Build relationships with inspectors and schedule early. Peak residential season hits May-September for cooling, but smart contractors balance books with heating work October-February. Emergency service pays premium rates, especially during heat waves and polar vortex events. Union presence is strong on commercial jobs.
