Fullerton Commercial Boiler Installation

#1 AC Guys provides end‑to‑end commercial boiler installation in Fullerton—engineering, permitting, installation, startup, and commissioning—optimized for efficiency, reliability, and lifecycle value. As a family business led by 4th‑generation engineers with 80+ years in engineering, we solve complex mechanical challenges while keeping your operations running.

Design–Build Hydronic Systems for Fullerton Facilities

Whether you operate a school, multifamily community, hotel, medical office, manufacturing site, office campus, or retail center, we tailor boiler plants to your loads, controls strategy, and budget. Our mission is healthy, safe indoor environments—and that starts with clean, well‑tuned heat and properly balanced hydronics.

• High‑efficiency condensing and non‑condensing commercial boilers
• Primary–secondary and variable‑primary pumping with VFDs
• Air separators, expansion tanks, dirt/magnetic filtration, water treatment
• Flue design, Category II/IV venting, combustion air and make‑up air
• Sequencing controls, BMS/EMS integration, remote monitoring
• Seismic supports, anchorage, and OSHPD‑style best practices where applicable

Code, Safety, and Compliance—Handled

We manage local permits and inspections for Fullerton and align your installation with California Mechanical Code, Title 24 requirements, and SCAQMD low‑NOx rules (including Rule 1146/1146.2 as applicable). Expect detailed submittals, clear as‑builts, and documented commissioning. Safety is built into every step—lockout/tagout, hot‑work procedures, and pressure testing are standard.

Our Installation Process

• Assessment and load calculations: We confirm true heating demand, turndown needs, and part‑load profiles for the right boiler capacity and redundancy.
• System design: Piping schematics, pump selection, control sequences, and venting modeled for stable delta‑T and condensing performance.
• Permitting and submittals: Title 24 documentation, SCAQMD compliance, manufacturer datasheets, and IOM packages prepared in‑house.
• Prefabrication and phasing: Skids and headers built off‑site where possible, with weekend or night cutovers to limit downtime.
• Installation: Clean, labeled piping; proper slopes; insulation; seismic anchorage; and code‑correct venting and combustion air.
• Startup, tuning, and commissioning: Combustion analysis, control set‑up, sensor verification, and sequence testing with full reports.
• Training, O&M, and handoff: Staff training, preventive maintenance plans, and warranty registration for long‑term reliability.

Serving Fullerton and Greater Southern California

Based in Southern California, we proudly serve Fullerton and all of Orange County, plus Los Angeles County, Ventura County, and Western Riverside County. If your project spans multiple sites or campuses, our team scales with consistent standards and documentation.

Engineered Performance You Can Measure

From modulating, low‑NOx condensing boilers to robust hydronic distribution and smart sequencing, we design for stable supply temperatures, optimal delta‑T, and reduced short‑cycling—backed by commissioning data you can trust. Cleaner combustion and proper water treatment protect heat exchangers, pumps, and valves, cutting unplanned downtime.
