Commercial Cooling Tower Repair in Fullerton

As a fourth‑generation family business, #1 AC Guys is built to solve difficult problems other contractors avoid. Our mission—healthy air for a healthy life—starts at the source: stable heat rejection, balanced water flow, and reliable controls. In Fullerton’s diverse commercial environment, cooling towers must endure seasonal heat, airborne debris, and variable loads. We restore performance, extend equipment life, and help you meet sustainability goals without sacrificing uptime.

What we repair and optimize

• Mechanical drive: fan assemblies, shafts, gearboxes, bearings, bushings, pulleys, belts, alignment, and vibration correction.
• Motors and power: high‑efficiency motor replacements, starter and VFD diagnostics, soft starts, overload protection, and electrical remediation.
• Thermal media: fill replacement/upgrades, drift eliminators, louvers, nozzles, distribution decks, and water balance to recover approach temperature.
• Basins and structure: leak detection and repair, corrosion mitigation, coatings, make‑up valves, floats, strainers, and structural reinforcement.
• Controls and sensors: VFD tuning, fan sequencing, temperature and level sensors, BMS integration, alarms, and seasonal optimization.
• Water performance: nozzle patterning, flow and bleed adjustments, and coordination with your water treatment vendor to protect assets and IAQ.

AC PRO parts and compatibility

We service AC PRO–supplied components and stock AC PRO–compatible parts such as motors, belts, bearings, control hardware, and maintenance materials to speed repairs and reduce downtime. Our team verifies compatibility, specs, and clearances to maintain performance and safety. If a part is end‑of‑life, we propose vetted alternatives that preserve capacity and efficiency.

Our commercial repair process

• Discovery: site walk, operating history, recent alarms, maintenance records, and visual inspection.
• Diagnostics: vibration and thermal checks, electrical testing, water distribution assessment, and component condition scoring.
• Plan and quote: root‑cause explanation, risk ranking, options (repair vs. refurbish vs. retrofit) with timeline and cost clarity.
• Execution: safety plan, lockout/tagout, part replacement, alignment, torque specs, basin remediation, and controls tuning.
• Verification: run test under load, approach temperature check, vibration baseline, leak check, and documentation for your records.
• Handover: maintenance tips, recommended spares, and seasonal checklist tailored to Fullerton’s climate profile.

Retrofits that cut energy and water use

When a fix alone isn’t enough, we design retrofits to improve reliability and reduce operating cost: VFDs for fan speed control, premium‑efficiency motors, upgraded fill and drift eliminators, improved nozzles for even distribution, and control sequences that match real load. Many upgrades deliver quick payback via energy savings, quieter operation, and longer component life.

Symptoms your cooling tower needs service

• Rising condenser water temperatures or poor approach under normal load.
• Persistent vibration, belt dust, or unusual noise from the fan stack.
• Visible drift, scaling, fouling, or uneven water distribution across fill.
• Frequent motor trips, VFD faults, or inconsistent make‑up water levels.
• Leaks, corrosion, or accelerated component wear despite regular treatment.

Detecting issues early prevents costly failures and helps maintain stable indoor environments. We collaborate with your water treatment provider and facility team to align mechanical fixes with water chemistry best practices.
