Expert Repair for Every Chiller Type

Glendale businesses rely on consistent cooling to protect people, product, and property. #1 AC Guys delivers precision Commercial Chiller Repair that restores capacity, lowers operating costs, and extends equipment life. We service:

Air‑cooled chillers: scroll and screw
Water‑cooled chillers: centrifugal, screw, magnetic‑bearing
Process and comfort cooling plants
Cooling towers, condenser water loops, and VFDs
AHU and FCU integration, valve actuation, and BMS controls

Common Symptoms We Fix

Whether it is a single unit or a multi‑chiller plant, our engineers quickly pinpoint root causes and correct them:

Insufficient cooling capacity, rising space temperatures, and hot‑spot complaints
High head pressure, nuisance trips, short‑cycling, and hard starts
Low delta‑T and poor heat transfer due to fouled tubes, scale, or biofilm
Refrigerant leaks, charge imbalance, non‑condensables, and oil carryover
Vibration, bearing wear, and abnormal sound profiles
Sensors out of calibration, control logic faults, and BMS integration issues
Pump cavitation, valve failures, and tower fan or fill deterioration

Our Repair Process

We combine field‑proven methods with modern diagnostics for fast, reliable outcomes. Expect:

Intake and assessment tailored to your building’s load profile and system design
Performance testing: pressures, temperatures, superheat/subcooling, and flow verification
Electrical checks: amperage, contactors, capacitors, VFDs, and megger insulation tests
Refrigerant and oil best practices aligned with EPA guidelines
Leak detection using ultrasonic and electronic tools; pinpoint repairs and evacuation
Tube cleaning and chemical treatment coordination to recover heat‑exchange efficiency
Controls calibration, staging optimization, and safe BMS sequencing
Final commissioning: capacity verification, alarm review, and documentation

Engineered Advantages You Can Measure

Our technicians are factory‑trained across leading global manufacturers—including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea, Gree, and Haier—so we confidently service mixed brands and legacy plants found across Glendale. You get:

Rapid response and minimal downtime for mission‑critical facilities
Transparent estimates and clear repair options before work begins

Healthy Air and Efficiency Go Together

Our mission is healthy air for a healthier life. Stable chilled water temperatures help your AHUs dehumidify properly, reduce mold risk, and improve indoor air quality for occupants and customers. We also optimize part‑load efficiency, staging, and condenser water setpoints to lower energy use without sacrificing comfort or process stability.

Preventive Maintenance That Pays Back

After repairs, we can set up a tailored maintenance plan to protect your investment:

Seasonal start‑up and shutdown services
Water treatment oversight and cooling tower hygiene
Vibration trend analysis and oil condition monitoring
Control strategy reviews and sensor recalibration
Tubeside inspection and cleaning schedules to preserve heat transfer

Small issues caught early prevent big failures, extend equipment life, and keep utility costs predictable.
