HVAC Jobs in Mesa, AZ

Phoenix and Tucson are among the hottest major metros in North America. Average summer highs routinely exceed 110°F in the Phoenix metro, which means residential and commercial HVAC systems are running at or near design limits for five to six months of the year. System failures in July and August are common, and service companies report significant overtime demand during heat events. Rooftop package units dominate the commercial segment; split systems are standard in residential.

Arizona HVAC contractors are licensed through the Arizona Registrar of Contractors (ROC) under the CR-39 license classification. EPA 608 certification is required for refrigerant handling. The Phoenix and Tucson markets have a large base of Carrier, Trane, and Lennox equipment, and familiarity with heat pump operation in dry climates is a differentiating skill for technicians interviewing with commercial accounts.
