Sinclair Air Systems installs commercial HVAC systems for offices, retail spaces, restaurants, warehouses, and other business properties across the San Gabriel Valley. We’re a licensed C-20 contractor with decades of experience in commercial work — from small office buildouts to large-scale rooftop unit installations.
Every commercial install starts with a site assessment. We evaluate your building’s layout, occupancy, and usage patterns to design a system that keeps your space comfortable without wasting energy. We handle equipment selection, installation, ductwork, controls, and final testing.
We install high-efficiency commercial systems that can lower your operating costs. We’ll walk you through available rebates and tax credits that can offset the upfront investment. Call (626) 331-4541 for a free commercial estimate.
