Cooling tower repair, replacement and maintenance

A cooling tower is where a water-cooled plant gets rid of its heat. When fans, drives, fill or water distribution aren't working well, the chiller pays for it. We handle the mechanical side of cooling tower service.

Mechanical work and water treatment are separate

Our cooling tower work covers mechanical equipment: fans, motors, gearboxes and belts, fill, drift eliminators, basins, distribution and controls. Chemical water treatment and water-quality testing are specialist responsibilities. We coordinate with your water treatment provider and don't present our mechanical work as a substitute for it.

Cooling tower repair

Repair calls usually start with a chiller running hot, a tower fan that won't run, unusual noise, or water where it shouldn't be.

  • Fan motor, gearbox, belt and bearing failures
  • Vibration and imbalance issues
  • Make-up water valve and float problems
  • Basin leaks and overflow
  • Clogged or damaged distribution nozzles and spray systems
  • Damaged fill or drift eliminators
  • Fan controls, VFDs and interlocks

Installation and replacement

Towers deteriorate structurally over time, particularly in coastal air. When repairs to casing, structure or basin are no longer practical, replacement or a major rebuild may be the better option.

  • Condition survey of structure, casing and basin
  • Full tower replacement planning, including rigging and roof loads
  • Component replacement: fill, eliminators, fan assemblies
  • Coordination with chiller and condenser water piping

Mechanical maintenance and performance checks

Routine mechanical maintenance keeps heat rejection consistent and helps avoid unplanned shutdowns.

  • Fan, motor and drive inspection and lubrication
  • Belt tension and alignment
  • Vibration checks
  • Fill and eliminator condition
  • Basin and strainer cleaning coordination
  • Make-up and float valve operation
  • Approach and range checks relative to chiller performance

  • Fan not running
  • Recent belt or gearbox work

What a technician would evaluate

  • Motor, belts and gearbox
  • Bearings and alignment
  • Vibration switch

How it works

Chilled-water and condenser-water loops

ChillerAir handlers / fan coilsCooling towerPumps & controls

The chiller cools water for the building; on water-cooled plants, condenser water carries heat to the cooling tower. Solid cyan: cooler side; dashed red: warmer side. Illustrative only, not an engineering design.

Evaporator & condenser

Heat exchangers inside the chiller. Fouling or flow problems reduce capacity and trigger alarms.

  1. Evaporator & condenser: Heat exchangers inside the chiller. Fouling or flow problems reduce capacity and trigger alarms.
  2. Chilled-water loop: Cooled water serves coils across the building and returns warmer.
  3. Cooling tower (mechanical): Fans, fill and distribution reject heat. Water treatment is a separate specialist responsibility.
  4. Pumps, valves & controls: Maintain flow and sequence equipment; flow faults are a common trip cause.

Making the call

Repair, rebuild or replace?

Tower decisions hinge on structural condition and how much of the tower needs work.

  • The structure and basin are sound
  • Problems are limited to drives, motors or distribution
  • Fill is in serviceable condition

These are common patterns, not a verdict on your equipment. We explain options after inspecting it.

Process

How cooling towers work is handled

  1. 01

    Describe the issue

    Tell us about the tower, the plant it serves and current symptoms.

  2. 02

    Inspect

    We inspect mechanical components, safely and with the right access.

  3. 03

    Recommend

    A written scope separates repair, rebuild and replacement options.

  4. 04

    Complete and coordinate

    We complete mechanical work and coordinate with your water treatment provider.

What to have ready

  • Tower make and model
  • Chiller and tower logs
  • Water treatment provider contact (for coordination)

What affects scope and cost

  • Mechanical components affected
  • Structural condition
  • Access and rigging

Good to know

  • Our scope is mechanical; chemical water treatment stays with your specialist provider
  • Basin cleaning and treatment programmes are coordinated, not replaced

We don't publish prices: cost depends on what's found on site and is explained before work starts.

Coverage

Across South Florida

Cooling towers requests are taken from properties in Miami, Broward County and Palm Beach County. Share your ZIP code and we'll confirm.

Service areas

Cooling towers questions

Do you provide water treatment?

No. Chemical treatment and water-quality testing are handled by specialist water treatment providers. We coordinate with yours on mechanical work, cleanings and shutdowns.

Our chiller runs hot in the afternoon. Could it be the tower?

It's a common cause. Fan problems, poor water distribution or fouled fill reduce heat rejection. We check the tower alongside the chiller.

How often should tower mechanical components be checked?

Regularly during the cooling season, with more detailed inspections periodically. We'll set a schedule based on your tower and its run time.

Do you handle water treatment?

No. We handle mechanical work and coordinate with your water treatment provider.

Can a tower be rebuilt instead of replaced?

Sometimes. It depends on structural condition and component availability.
