Cooling Tower Repair, Rebuilds & Maintenance in Chicagoland
For over 30 years, J&L Cooling Towers has helped commercial, industrial, and institutional facilities extend equipment life, prevent costly downtime, and keep systems running safely and efficiently.
Cooling Tower Problems Get Expensive — Fast
Small issues become major failures when they’re ignored. We catch them early and fix them right the first time.
Leaks & Basin Damage
Cracked basins and failing seals waste water and threaten the structure below.
Corrosion & Rust
Untreated corrosion eats steel and shortens the life of the entire unit.
Poor Performance
Clogged fill and scale rob efficiency and drive energy costs through the roof.
Damaged Fill Media
Collapsed or fouled fill kills cooling capacity and overworks the system.
Motor & Gearbox Failure
Worn bearings, belts and gear reducers can stop a tower cold without warning.
Vibration & Noise
Excess vibration signals imbalance or failing components — and tenant complaints.
Basin Deterioration
Worn hot & cold water basins lead to overflow, splash-out and corrosion spread.
Unplanned Downtime
A tower failure on a hot day means no cooling — and a building-wide emergency.
