Commercial Boiler Repair in Anaheim, CA

Our Commercial Boiler Repair Expertise

From single hydronic boilers to multi‑boiler plants with lead‑lag sequencing, #1 AC Guys brings engineering‑level diagnostics and repair to Anaheim businesses. We specialize in complex mechanical rooms and mission‑critical facilities where uptime, safety, and energy performance matter most. Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), and we apply rigorous methods that go beyond quick fixes to deliver lasting results.

• Hydronic and steam boilers: condensing and atmospheric
• Low NOx and high‑efficiency systems
• Burners, gas trains, ignition and flame safeguard
• Pumps, separators, expansion tanks, and air vents
• Heat exchangers, coils, and plate‑and‑frame units
• Controls, sensors, actuators, and VFDs
• Lead‑lag sequencing and BAS integrations (BACnet, Modbus)
• Venting, draft, and combustion air corrections
• Water treatment guidance and scale mitigation

Our mission is healthy indoor air for a healthy life. Reliable heat and clean, balanced systems are essential to occupant well‑being and productivity—especially in offices, hospitality, healthcare, education, multifamily, and light industrial environments.

When to Call for Boiler Repair

• Lockouts, nuisance trips, or frequent resets
• Uneven heat, cold zones, or slow recovery
• High gas usage or unexplained energy spikes
• Leaks, corrosion, or discolored water
• Banging, whistling, or kettling sounds
• Flue drafting issues or combustion odors
• Air in system, low pressure, or cavitating pumps

Minor symptoms often signal deeper issues. Addressing them early prevents component failures, protects the heat exchanger, and preserves warranty and code compliance.

Our Diagnostic Process

We begin with a structured interview and site walk, then complete a multi‑point engineering checklist. Key steps include:

• Combustion analysis and tuning for safe, efficient firing
• Draft and vent evaluation, combustion air verification
• Electrical and controls testing, sensor calibration, and safeties
• Hydronic balance checks: delta‑T, flow, and pump operation
• Heat exchanger inspection and thermal performance review
• Water chemistry testing and treatment recommendations
• Lead‑lag and sequencing optimization to reduce short cycling

At the end, you receive a clear action plan with prioritized options, budget ranges, and timelines—so you can make informed decisions without surprises.
We document readings and settings to benchmark performance and support maintenance planning.

Preventive Maintenance and Optimization

Proactive care prevents costly breakdowns and keeps comfort consistent through peak seasons. Our maintenance programs are tailored to usage, fuel type, and plant size.

• Seasonal startup and shutdown procedures
• Annual combustion tuning and safety testing
• Pump alignment, lubrication, and seal inspections
• Controls verification and sensor recalibration
• Glycol and water treatment monitoring
• Filter, strainer, and trap service
• Optimization for condensing operation and reset schedules

These steps reduce energy waste, extend equipment life, and create steadier temperatures for healthier, more productive indoor environments.

Safety and Code Focus

We repair with safety and compliance in mind, aligning with California Mechanical Code and local authority requirements. That includes proper venting and combustion air, verified safeties, and documentation to support inspections. Our aim is to restore reliable operation and help keep your system ready for regulatory reviews while minimizing disruption to your business.
