Commercial Boiler Repair in Fontana | AC PRO

Keeping your Fontana facility heated and productive depends on a boiler partner who can solve problems under real‑world constraints—tight timelines, strict safety rules, and budget accountability. #1 AC Guys specializes in commercial boiler repair for AC PRO hydronic and integrated HVAC equipment, bringing fourth‑generation engineering rigor to every service call.

What we repair and optimize

• Combustion and ignition: flame failure, short cycling, high CO/CO₂, gas valve and air‑fuel ratio setup
• Hydronic circulation: pump failures, air binding, cavitation, clogged strainers, expansion tank issues
• Controls and BMS: sensor drift, staging problems, lockouts, boiler sequencing, VFDs, and setpoint strategy
• Heat exchangers and piping: leaks, scale, condensate management, primary/secondary and reverse return balancing
• Efficiency restoration: condensing return temps, delta‑T optimization, combustion tuning, heat‑loss corrections

We service condensing and non‑condensing commercial boilers, water‑tube and fire‑tube designs, and hybrid plants tied to AC PRO air handlers, fan coils, and rooftop equipment. If your plant is tripping on safety, losing heat, or wasting fuel, we find the root cause—not just the symptom.

• Data‑driven diagnostics: combustion analyzers, delta‑T logging, and flow verification for evidence‑based repairs
• Code‑compliant delivery: Title 24, local building codes, and safety best practices built into every step
• Clear documentation: photos, readings, and recommendations you can share with ownership and operations

Our mission is healthy air and safe, efficient heat for a healthier life at work and at home. In boiler rooms, that means clean combustion, correct ventilation, proper water chemistry, and reliable controls that protect people and property.

AC PRO commercial expertise

We repair and optimize AC PRO commercial hydronic and integrated HVAC equipment, interface with AC PRO‑supplied components, and source compatible parts through established distribution channels to shorten downtime. Whether you need a burner tune, pump replacement, control recalibration, or a strategy to reduce gas consumption, we align service with your operational goals.

Our repair process

• Assessment: review alarms, operating history, and visible conditions; safety checks first
• Testing: combustion analysis, flue draft, gas pressure, pump performance, sensor validation
• Root‑cause fix: targeted repair or component replacement with verified readings
• Optimization: setpoints, staging, and hydronic balance to curb cycling and costs
• Proof and handoff: before/after data, photos, and preventive recommendations

Need predictable timelines? We offer rapid scheduling and coordinated shutdowns to minimize impact. For multi‑boiler plants, we can sequence work to keep heat online.

Industries we serve

• Logistics, distribution, and cold chain support
• Manufacturing and processing facilities
• Healthcare, labs, and medical offices
• Hospitality, retail, offices, and mixed‑use
• HOAs, schools, and places of worship

From Sierra Lakes to the I‑10/I‑15 corridor, we understand Fontana’s operational demands—early starts, high loads, and tight facility windows. Our team adapts to your schedule and safety protocols.

Preventive maintenance that pays back

Avoid emergency shutdowns with seasonal combustion tuning, water chemistry checks, and control calibration. We customize maintenance for AC PRO hydronic plants, including burner cleaning, electrode inspection, condensate neutralizer service, and pump verification. The result: fewer outages, lower utility bills, and longer equipment life.

Safety and compliance

We follow manufacturer procedures and local code requirements, document gas and combustion readings, and verify safeties, ventilation, and clearances. Our approach supports inspections and keeps your liability low.

Service area

Based in Greater Los Angeles, we proudly serve Fontana and nearby Inland Empire communities, as well as Los Angeles County and adjacent areas including Orange County, Ventura County, and Western Riverside County. If you operate multiple sites, we can coordinate service across locations.
