Commercial Boiler Repair in Los Angeles

Commercial properties in Los Angeles rely on steady, efficient heat to safeguard people, processes, and property. At #1 AC Guys, we approach every boiler room like an integrated system—boiler, pumps, valves, expansion, venting, water treatment, and controls—so repairs are durable, efficient, and compliant with California codes and local AQMD requirements.

What we repair and service

• Hydronic and steam boilers: standard, high‑efficiency, and condensing
• Burners and ignition systems: pilot, electronic, and low‑NOx configurations
• Heat exchangers: leaks, fouling, scaling, and thermal stress
• Pumps, valves, and expansion tanks: flow, pressure, and air management
• Controls and safety devices: sensors, limit controls, actuators, VFDs, BAS integration
• Venting and flue systems: draft, condensation management, and code compliance
• Water quality: treatment, filtration, corrosion prevention, and sludge mitigation

Signs your commercial boiler needs service

• Short cycling, lockouts, nuisance trips, or rising gas/electric costs
• Uneven heating, cold zones, or chronic air in the system
• Delayed ignition, noisy operation, or combustion instability
• Visible leaks, corrosion, scaling, or frequent makeup water
• Flue condensation, odors, or failed combustion analysis

Addressing issues early prevents costly outages and extends equipment life. We combine field measurements, combustion analysis, and system balancing to find root causes—not just symptoms.

Our engineered repair process

• Diagnose: Measure temperatures, pressures, flows, and combustion data; review controls and sequence of operations; verify code compliance.
• Stabilize and repair: Correct safety faults first, then address mechanical, hydraulic, and control issues with OEM‑grade parts.
• Verify and document: Post‑repair testing, combustion tuning, and performance reporting so you know your system is safe and efficient.

As a 4th‑generation engineering family with 80+ years of engineering expertise, we specialize in complex boiler rooms for high‑load, multi‑zone buildings. Our team is trained at manufacturer facilities—Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)—bringing disciplined, factory‑informed practices to your site.

Preventive maintenance for uptime and efficiency

A proactive plan reduces breakdowns and energy spend. We tailor maintenance to your equipment type, runtime, water quality, and occupancy profile.

• Seasonal start‑ups and shutdowns, safety checks, and combustion analysis
• Water treatment verification, flushing, and air removal for optimal heat transfer
• Controls calibration, sensor validation, and sequence optimization
• Pump alignment, bearing checks, VFD tuning, and flow balancing
• Documentation and recommendations to plan upgrades before failures occur

Retrofits and efficiency upgrades

Many LA buildings can capture significant savings through targeted improvements. We recommend upgrades only when they deliver measurable value.

• Condensing boiler conversions with proper return‑water temps and venting
• Advanced controls, O2 trim, demand‑based sequencing, and BAS integration
• Variable speed pumping, hydraulic separation, and primary–secondary piping
• Heat exchanger replacements and right‑sizing to the actual load profile
• Water quality enhancements to prevent scaling and corrosion

Our mission is healthy air and comfortable spaces for a healthier life—achieved through safe combustion, stable temperatures, and efficient systems that reduce emissions and operating costs.
