About This Market
Dearborn's HVAC market runs hot and cold with the seasons. You've got older residential stock needing constant furnace work through brutal Michigan winters, plus newer builds demanding efficient systems. Competition's thick with 2574 licensed establishments statewide, but good contractors stay busy year-round. Costs get driven up by Michigan's energy efficiency requirements and the need for equipment that handles -10°F to 95°F swings. Commercial work comes from Ford Motor Company facilities and industrial base, but residential replacement and repair makes the bread and butter. Getting licensed in Michigan means jumping through LARA hoops - 4 years experience, written exam on mechanical codes, and that $50,000 bond that'll make you think twice. Dearborn Building Department runs a tight ship on permits and inspections, so don't try to skip steps. Peak season splits between furnace season (October-March) and AC season (May-September), with April being your only breathing room. Smart contractors stock parts for both seasons and build relationships with suppliers who can deliver fast when equipment fails during temperature extremes.
