Glendale Commercial Boiler Repair

When your commercial boiler falters, every hour of downtime impacts tenants, guests, patients, and productivity. #1 AC Guys combines deep engineering discipline with practical field experience to restore heat fast, stabilize operations, and optimize efficiency for the long haul. Our family business is in its fourth generation, with 80+ years of engineering know-how applied to complex mechanical rooms across Glendale and greater Los Angeles.

What we repair and optimize

• Hot-water boilers (condensing and non-condensing), steam boilers, and modular plants
• Pumps, VFDs, expansion tanks, air separators, and balance valves
• Burners, gas trains, igniters, flame sensors, and safety interlocks
• Heat exchangers, economizers, and flue/venting systems
• Water chemistry and treatment for longevity and scale control
• Boiler sequencing, lead/lag logic, and BMS integration
• Low-NOx upgrades, combustion tuning, and emissions documentation

From uneven heating and nuisance lockouts to surge gas usage and alarming controls, we locate root causes—mechanical, electrical, or controls-related—and implement durable, code-compliant repairs. We also calibrate and commission the system to ensure reliable, repeatable performance.

Symptoms that signal it’s time to call

• Cold zones, slow recovery, or frequent short cycling
• Rising utility bills without added demand
• Lockouts, error codes, and unexplained shutdowns
• Kettling, banging, or cavitation noises
• Leaks, corrosion, or combustion odors
• CO or draft alarms, poor combustion test results

Addressing issues early prevents secondary damage to pumps, heat exchangers, and controls—and protects your budget and business continuity.

Our mission is healthy indoor environments and dependable comfort. We engineer solutions that lower life-cycle costs, reduce emissions, and support the well-being of occupants and staff.

Our engineered repair process

• Assess: Document symptoms, alarms, and operating history; inspect mechanicals, gas supply, venting, and water quality.
• Diagnose: Test safeties and sensors, analyze combustion, verify pump curves and flows, and review controls/sequence of operations.
• Stabilize: Mitigate immediate risks, restore safe operation, and establish baseline performance.
• Repair: Replace failed components with OEM-grade parts, correct piping or venting issues, and update programming where needed.
• Commission: Balance flows, tune combustion, verify lead/lag, and capture before/after data.
• Protect: Provide recommendations for water treatment, filtration, and proactive maintenance to extend system life.

For facilities that require speed, we coordinate off-hours work to minimize disruption. Need specific parts? We can source components through AC PRO to align with your procurement standards and timelines.

Industries and properties we serve

• Office towers, mixed-use, and multi-tenant facilities
• Hotels, resorts, and event venues
• Hospitals, clinics, and laboratories
• Schools, universities, and municipal buildings
• Manufacturing, warehouses, and data/tech campuses
• Retail centers and places of worship

Whether your boiler room serves a single mid-rise or a multi-building campus, we design repairs that work within your load profile, controls strategy, and budget—without sacrificing safety or code compliance.

Maintenance that prevents breakdowns

Planned service protects your investment. Our commercial maintenance includes combustion testing, burner cleaning, gasket and trap checks, pump and VFD inspections, water chemistry management, and verification of safeties. Routine tuning can reclaim lost efficiency, reduce cycling, and catch small issues before they become major outages.

Compliance, safety, and documentation

We help Glendale property teams navigate inspections and environmental requirements. Expect clear documentation, photos, and test reports suitable for your internal audits and external compliance needs. When low-NOx or retro-commissioning is required, we align the work with SCAQMD and Title 24 expectations.

Service area

Based in Los Angeles County, we proudly serve Glendale and the surrounding region—Los Angeles County at large, as well as Orange County, Ventura County, and Western Riverside County. If you manage multiple properties, ask about coordinated scheduling across sites.
