What we repair and upgrade

• Mechanical systems: fan assemblies, motors, VFDs, gearboxes, drives, shafts, bearings, and vibration isolation
• Thermal media & drift control: fill media, drift eliminators, nozzles, distribution decks
• Basin & structure: leaks, corrosion mitigation, coatings, sump screens, strainers, make‑up valves
• Water & treatment interfaces: scale/biofilm remediation coordination and performance restoration
• Controls & sensors: temperature and level sensors, conductivity probes, safeties, BAS/BMS integration
• Noise & plume: mitigation strategies, air pathways, and fan speed optimization

Every repair plan starts with a thorough assessment—airflow, water flow, approach temperatures, vibration signatures, and visual inspection. We isolate root causes, not just symptoms, then present options that balance cost, downtime, and long‑term reliability.

Our streamlined process

• Assessment: on‑site diagnostics, safety review, and performance baselining
• Plan: scope, schedule, and budget with clear milestones
• Repair: precision execution, from component replacement to structural remediation
• Commission: verify flows, temperatures, and controls; document improvements
• Handover: maintenance guidance, parts lists, and recommended monitoring

Need it done quickly? We prioritize Pasadena dispatch and coordinate crane lifts, permits, and deliveries to compress timelines while maintaining safety and quality.

Parts and sourcing

To speed repairs and control costs, we utilize OEM and high‑spec replacement components available through Southern California supply channels, including AC PRO availability where appropriate. This local sourcing helps reduce lead times and gets your system back online sooner.

Safety, compliance, and documentation

We adhere to rigorous safety protocols and provide documentation for AHJ and site requirements. Our commissioning records include measured flows, temperatures, setpoints, and verification steps so your facilities team has full transparency.

Energy‑focused retrofits

• High‑efficiency fan motors and VFDs for optimized part‑load operation
• Controls tuning and BAS integration to stabilize approach temperature
• Improved fill and drift eliminators to enhance heat transfer and reduce water loss
• Targeted water distribution upgrades to correct bypass and hotspots

These upgrades can cut energy consumption, stabilize comfort, and extend equipment life—often with attractive paybacks.

Preventive maintenance plans

Proactive maintenance reduces unplanned downtime and protects your investment. Our commercial PM programs include scheduled inspections, vibration trending, torque checks, belt/drive evaluation, nozzle cleaning, basin hygiene review, and sensor calibration—aligned to your operating schedule.
