About This Market
Fresno's HVAC market runs hot - literally and figuratively. Central Valley heat drives massive cooling demand from May through October, with summer temps regularly hitting 105°F+. Competition is fierce among the area's contractors, but volume keeps everyone busy. Residential replacements dominate, with lots of older units failing under extreme heat loads. New construction adds steady work, but retrofit and replacement jobs pay better margins. Cost drivers include equipment availability, refrigerant regulations, and the sheer brutality of attic work in 120°F+ conditions.
To work Fresno, get your C-20 license squared away first - no shortcuts. City permit process is straightforward but required. Peak season means 60-hour weeks and premium pricing for fast response. Stockpile common equipment before summer hits - supply chain delays kill profits when customers are desperate. Know your refrigerant handling - EPA 608 certification is non-negotiable. Commercial work requires deeper relationships but provides winter income when residential slows. Cash flow management is critical - customers pay fast in summer heat, slow in winter. Keep insurance current and workers hydrated.
