Air conditioning is always in high demand in Michigan. I imagine that any state with our climate has the same needs for competent technicians. The state has two extreme weather seasons, hot summers and freezing winters, making this state one of the best places with a high demand for HVAC services. Like the District of Columbia, New Jersey has hot summers and cold winters.
HVAC technicians would have to adapt to the increasing fluctuations in the varying climate of different seasons.
