Cooling Tower Maintenance & Repair for NYC Buildings
A neglected cooling tower drags down chiller efficiency and creates health and compliance risk. Com+ Mechanical maintains, cleans and repairs cooling towers across NYC and Long Island, working alongside your water-treatment provider.
Common Cooling Tower Problems
High condenser water temperature
Scaled fill, failing fans or poor water distribution reduce tower capacity.
Vibration or noise
Worn gearboxes, bearings or unbalanced fans.
Water loss or overflow
Bad float valves, leaking basins or damaged drift eliminators.
Visible scale or algae
Water-treatment problems that hurt efficiency and raise health risk.
Corroded structure
Deteriorating basins and frames that need repair before they fail.
Why Cooling Tower Maintenance Matters
Cooling towers reject heat from water-cooled chillers. Scale, debris and biological growth reduce heat transfer, push chiller energy up and can harbor Legionella. In New York City, cooling towers must be registered and maintained under a written management plan with regular inspections. We handle the mechanical side (fans, motors, gearboxes, fill, basins and controls) and coordinate with your water-treatment vendor.

Frequently Asked Questions
Get answers to common questions about our services
How often should a cooling tower be maintained?
Towers need startup and shutdown service each season plus regular in-season checks. Frequency depends on the tower and your water-treatment plan.
Do cooling towers in NYC have to be registered?
Yes. New York City requires cooling towers to be registered and maintained under a management plan with regular inspections. Your water-treatment provider and contractor typically share this work.
Do you clean cooling towers?
Yes. We clean basins, fill and drift eliminators and coordinate disinfection with your water-treatment vendor.
Can a dirty cooling tower raise energy bills?
Yes. Scale and debris reduce heat rejection, which makes the chiller work harder and use more energy.
