Commercial Cooling Tower Repair in Los Angeles

Why #1 AC Guys for Cooling Tower Repair in Los Angeles

We are a fourth‑generation family business with 80+ years in engineering, built to handle complex commercial systems. Our team combines precision diagnostics with field‑proven repair practices to restore capacity, stability, and efficiency for towers supporting chilled water plants and process cooling. Trained at the manufacturers’ facilities of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), we bring meticulous standards, clear documentation, and dependable timelines.

• Deep engineering heritage for high‑stakes facilities
• Commercial focus: large buildings and multi‑tower plants
• Safety and compliance culture (CTI guidance, ASHRAE 188, Title 24)
• Local expertise with LA climate, drought, and water quality realities
• Coverage across Los Angeles County, Orange County, Ventura County, and Western Riverside County

Common Cooling Tower Problems We Resolve

• High approach temperatures, poor heat rejection, and seasonal capacity loss
• Excess vibration, bearing noise, misalignment, and unbalanced fans
• Motor trips, gearbox leaks, sheaves/belts wear, and driveshaft issues
• Corrosion, leaks, degraded coatings, and structural fatigue
• Scaled or fouled fill media, biofilm, algae, and drift control issues
• Clogged nozzles, poor distribution decks, and plugged strainers
• Basin sediment, poor sump hydraulics, and make‑up/blowdown failures
• Controls faults, VFD trips, sensor drift, and BMS communication issues

Our Repair Process

We start with a performance and safety assessment, reviewing thermal data, vibration, electrical health, water chemistry, and structural condition. We then provide a prioritized scope, timeline, and parts strategy (OEM or high‑grade equivalents), coordinate access and crane logistics if needed, and execute under strict lockout/tagout and fall‑protection procedures. Final commissioning includes alignment verification, vibration trending, amp draw checks, and baseline reporting for your records.

Mechanical Repairs and Rebuilds

• Fan systems: blades, hubs, pitch, balance, stacks, guards
• Drives: gearboxes, driveshafts, couplings, bearings, belts, and sheaves
• Motors and VFDs: replacement, soft starts, variable speed optimization
• Water distribution: nozzles, headers, valves, strainers, make‑up and blowdown controls
• Heat exchange media: fill replacement, drift eliminators, louvers, and air‑inlet repairs
• Basin and structure: cleaning, descaling, corrosion mitigation, coatings, fasteners, and casing panels

Where beneficial, we implement upgrades such as variable speed fan control, enhanced fill and drift packages, smarter blowdown control, and improved sensors for tighter BMS integration (BACnet/Modbus). These measures can stabilize approach temperatures, reduce noise, and lower kW/ton and water usage.

Water‑Side Reliability and Risk Management

Cooling tower performance depends on consistent water care. We coordinate with your chosen water‑treatment provider to address scaling, corrosion, and microbiological growth, and we support documentation aligned with ASHRAE 188 risk management. Options can include side‑stream filtration, improved bleed control, and basin hygiene plans that help limit fouling while supporting reliable heat transfer.

Preventive Maintenance for Los Angeles Conditions

LA’s heat, air quality, and water hardness require disciplined maintenance. We tailor PM programs around seasonal demand, including cleaning and inspection of fill and drift eliminators, nozzle/deck checks, belt tension and alignment, gearbox oil service, vibration trending, and sensor calibration. The goal: reliable, quiet operation and predictable capacity through heat waves and peak utility rates.

Industries We Serve

• Commercial offices, mixed‑use, and high‑rise campuses
• Hospitality, entertainment venues, and retail complexes
• Healthcare facilities and laboratories
• Data centers and technology hubs
• Manufacturing and light industrial

Compliance, Safety, and Local Requirements

Our methods align with relevant codes and industry guidance, including California energy standards and cooling tower best practices. We document work, provide photos and balances where applicable, and assist with utility incentive research (such as local programs that may be available) to help optimize lifecycle costs.
Where required, we support seismic anchorage and structural considerations to meet local authority expectations.

Service Area and Scheduling

We dispatch across Los Angeles County and nearby regions—Orange County, Ventura County, and Western Riverside County—fitting work windows around your operations. Expect clear communication, tidy job sites, and a focus on maintaining building comfort and process stability throughout repairs.
