Alabama experiences a humid subtropical climate with long, hot, humid summers and short, mild winters. Construction runs year-round, but July-August heat indexes regularly exceed 105°F and slow exterior work, while the Gulf Coast counties face an active June-November hurricane season that can tighten material supply and insurance terms. For furnace installation projects specifically, this means timing and material selection are key factors in both cost and quality.
Less regulatory burden and simpler permitting processes help keep overall project costs down.
