What we repair on AC PRO commercial chiller systems

• Air‑cooled and water‑cooled chillers (scroll, screw, and multi‑circuit configurations)
• AC PRO chiller components, OEM‑grade replacements, and compatible parts
• Compressors, oil management, economizers, and expansion devices
• Condenser and evaporator coils, heat exchangers, and plate/frame units
• Pumps, strainers, and flow/pressure imbalances affecting delta‑T
• Controls, sensors, BMS integration, and setpoint/logic faults
• VFDs and soft‑starters: nuisance trips, harmonics, and tuning
• Refrigerant leaks, charge optimization, and recovery per EPA 608
• Water quality issues impacting capacity, scale, and corrosion

Symptoms that signal you need service now

• Inconsistent chilled‑water temperature or low delta‑T
• High head pressure, frequent lockouts, or short‑cycling
• Unusual vibration, noise, or oil residue at fittings
• Rising energy bills with no change in load
• Repeated BMS alarms or sensor drift
• Visible icing, coil fouling, or poor heat transfer

If you see any of the above at your Oxnard facility, our team can rapidly isolate the root cause, prevent collateral damage, and protect product quality, comfort, and compliance.

AC PRO parts and logistics—built for speed

We coordinate AC PRO component sourcing and carry common OEM‑grade parts to compress lead times. From contactors and sensors to compressors and VFDs, our procurement process targets minimal downtime while maintaining manufacturer specifications and code requirements.

Our repair process

• Assessment and stabilization: Verify load, flows, setpoints, and safety.
• Advanced diagnostics: Trending, superheat/subcooling, oil analysis, and electrical testing.
• Root‑cause report: Clear findings, corrective options, and transparent pricing.
• Precision repair: OEM‑grade parts, clean brazing practices, and calibrated instruments.
• Optimization: Controls tuning, refrigerant charge verification, and performance baselining.
• Verification: Load test and documentation for your maintenance records and BMS team.

Compliance, safety, and sustainability

We follow EPA 608 refrigerant handling, California energy and mechanical codes, and best practices for leak prevention and recovery. Our work helps you align with efficiency targets under California Title 24 and local utility programs while improving reliability and occupant well‑being—true to our mission of healthy air for healthy lives.

Preventive maintenance that pays for itself

After repair, we can enroll your chiller in a tailored maintenance plan that stabilizes performance and reduces unplanned outages.

• Quarterly inspections tuned to your load profile
• Coil cleaning, water‑side checks, and flow verification
• Controls calibration and sensor validation
• VFD health checks and electrical testing
• Leak checks, charge optimization, and oil sampling
• Performance reports to forecast issues before they escalate
