Commercial Boiler Repair in Orange, CA

At #1 AC Guys, commercial boiler repair is handled by true engineers, not guesswork. Serving Orange and the wider Orange County area, our team blends rigorous diagnostics with practical field experience to restore safe, efficient heat while protecting your budget and timeline. We are a 4th‑generation family business with 80+ years in engineering, and our specialists are trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We also source OEM‑grade parts and accessories from trusted distributors like AC PRO to minimize downtime.

Systems We Repair and Optimize

• Commercial hydronic hot‑water boilers (condensing and non‑condensing)
• Low‑pressure steam boilers for legacy and specialty applications
• Primary/secondary pumping, air separators, expansion tanks, and PRVs
• Burners, gas trains, ignition systems, flame safeguards, and sensors
• Boiler controls: lead/lag, staging, BMS integration, and setback strategies
• Heat exchangers, coils, mixing valves, and radiant/hydronic distribution
• Combustion air, venting, flue piping, and draft components

Fast, Code‑Compliant Commercial Boiler Repair in Orange

We act quickly without cutting corners. Our process aligns with California Mechanical Code, AQMD guidelines, and Title 24 energy standards. After stabilizing heat, we investigate root causes—water chemistry, flow imbalance, air entrainment, fouled HX surfaces, failed sensors, gas pressure irregularities, or control logic conflicts. Then we present repair options, lifecycle impact, and efficiency upgrades so you can choose with confidence.

Common Issues We Solve

• No heat or intermittent shutdowns due to ignition, flame proving, or lockouts
• Kettling, short cycling, low efficiency, and excessive fuel consumption
• Leaking heat exchangers, relief valve discharge, and low system pressure
• Pump failures, air binding, cavitation, and improper expansion tanking
• Sensor drift, control board faults, and BMS communication errors
• Flue condensation, corrosion, and unsafe combustion/venting conditions

Our Engineer‑Driven Diagnostic Approach

We combine instrumentation and experience to pinpoint failures quickly. Expect combustion analysis, differential pressure checks, GPM verification, temperature delta profiling, and control sequence validation. When needed, we perform water sampling, scale inspection, and heat‑exchanger cleaning to restore design performance and protect your asset.

Healthy Buildings Start with Safe Boilers

Our mission is healthy air for healthy living. For boiler plants, that means verified combustion safety, proper makeup air, tight venting, and CO monitoring where applicable. We also address system cleanliness—filtration at strainers, air/dirt separation, and water treatment—to keep coils, pumps, and heat exchangers performing efficiently.

Energy and Performance Upgrades

When repair opens the door to savings, we can design improvements that often pay back quickly: smart lead/lag control, outdoor reset, delta‑T optimization, variable‑speed pumping, and demand‑based staging. For older plants, we evaluate right‑sizing, boiler sequencing, and heat‑recovery opportunities that align with Title 24 and your utility incentives.
