Commercial Boiler Repair in Los Angeles for AC PRO Systems

When a commercial boiler goes down in Los Angeles, every minute counts. #1 AC Guys delivers fast, methodical repair for AC PRO–based hydronic heating systems—reducing downtime with accurate testing, correct parts, and clean workmanship. Our engineering DNA shows in the details: we verify combustion health, water quality, and flow balance before replacing components, so you get a true fix, not a temporary patch.

What we repair and optimize

• Ignition and flame safeguard systems: electrodes, sensors, flame rectification, and lockouts
• Circulator pumps, zone valves, air separators, expansion tanks, vents, and pressure issues
• Heat exchangers: scaling, fouling, condensing coil maintenance, and thermal stress mitigation
• Gas trains and combustion setup: regulators, valves, manifolds, combustion tuning for efficiency
• Controls and BMS integration: outdoor reset, staging, lead/lag, and sensor calibration
• Safety and compliance: relief valves, low-water cutoff, venting, and code corrections
• Efficiency upgrades: high-turn-down burners, ECM pumps, insulation, and water treatment

We service commercial properties across Los Angeles—Class A offices, retail centers, restaurants, hotels, healthcare, schools, manufacturing, and multifamily. Whether your system uses AC PRO components or integrates AC PRO parts within a larger plant, our team understands how to stabilize combustion, restore flow, and control temperature for consistent comfort and lower utility spend.

Our engineering-first process

1) Assess: We gather system data—error codes, delta-T, combustion metrics, glycol mix, and water chemistry—before touching a wrench.
2) Diagnose: Root-cause analysis prevents repeat failures. We isolate electrical, mechanical, and control interactions that drive faults.
3) Repair: We install properly rated components and gaskets, set combustion, bleed air, balance flow, and verify safeties.
4) Prove: Post-repair testing documents efficiency, runtime stability, and code compliance to protect your operations and warranties.
