#1 AC Guys designs and installs Bosch commercial boiler systems that cut operating costs and stabilize comfort for offices, multifamily, schools, healthcare, hospitality, and industrial spaces. As a 4th‑generation family business with 80+ years in engineering, we excel at complex hydronic retrofits and new construction. Our mission is healthier buildings—cleaner combustion, safer venting, optimal water temperatures, and indoor environments that support productivity and well‑being. We deliver end‑to‑end service: load calculations, system right‑sizing, cascade controls, low‑NOx solutions, BMS integration, permitting, and commissioning. Serving Los Angeles County and nearby Orange, Ventura, and Western Riverside counties, our licensed team provides code‑compliant, on‑schedule installations backed by proactive maintenance and responsive support.
When your building depends on heat, hot water, or process loads, you need more than a boiler swap—you need a correctly engineered hydronic system. #1 AC Guys provides full design‑build services for Bosch commercial boilers, from detailed heat‑loss analysis to hydronic schematics and controls logic. We handle venting and combustion air strategies, flue materials, gas pipe sizing, primary/secondary piping, air and dirt separation, expansion tank selection, and redundancy planning.
Our approach reduces lifecycle costs while improving reliability and comfort across diverse occupancies.
Bosch commercial condensing boilers are known for robust heat exchangers, high turndown ratios, and dependable control platforms—ideal for retrofits and new builds in Los Angeles. Properly engineered, they deliver significant fuel savings and stable supply temperatures for critical operations.
Pairing Bosch with our engineering‑first design ensures your investment pays back in performance and longevity.
Our mission is healthier indoor environments. We emphasize safe combustion, correct ventilation, stable hydronic temperatures, and clean system water—factors that protect equipment and support occupant well‑being.
We support a wide range of commercial and institutional clients:
Whether replacing an aging boiler plant or designing for new construction, our team balances first cost, efficiency, and long‑term serviceability.
We begin with a site survey and data gathering: equipment inventory, load profile, venting paths, gas service, electrical, and controls. Next, we model options—single boiler vs. cascaded array, condensing strategies, and control sequences—to match budget and performance goals.
Expect meticulous attention to detail, from flue routing and condensate management to sensor placement and pump selection.
Our installations meet local and state requirements, including permitting with the Los Angeles Department of Building and Safety and applicable energy codes. We implement low‑NOx solutions where required, provide seismic bracing, verify gas pressure and combustion, and document commissioning data. Safety and performance are never optional.
Our engineers maintain deep manufacturer knowledge and hands‑on factory education with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That engineering foundation informs every hydronic and HVAC decision we make—especially on the largest, most complex projects.
We proudly serve Los Angeles County and nearby Orange County, Ventura County, and Western Riverside County. If your property sits near the county lines, call us—we regularly mobilize crews across the region.
