Arizona experiences a hot, arid desert climate in the southern regions and mountain conditions in the north. Extreme summer heat (110°F+) limits outdoor work to early morning hours from June-August. Year-round construction is possible with proper scheduling. For ac unit installation projects specifically, this means timing and material selection are key factors in both cost and quality.
Arizona's costs are close to the national average, reflecting a balanced supply-demand dynamic in the local construction market.
