About This Market
Fresno's HVAC market runs on extreme heat - summers regularly hit 105°F+, making AC essential, not optional. The Central Valley location means year-round work with residential retrofits, new construction serving population growth, and agricultural facility work. Competition is moderate with established players, but demand consistently outpaces supply during peak months. Costs run slightly below state average due to lower overhead, but equipment costs remain fixed statewide.
To work Fresno, get your C-20 license first - no shortcuts. The 4-year experience requirement is real, and the trade exam covers refrigeration theory, load calculations, and code requirements. City permit process is straightforward but required for everything. Stock inventory before May - supply chains get stretched during peak season. Focus on relationships with suppliers and maintain emergency service capability - that's where the real money is when it's 110°F and someone's AC dies.
