What We Service
Cooling towers and chillers both remove heat—but they do it differently. Knowing what your facility has helps you plan the right maintenance and avoid expensive failures.
Chillers
Remove heat from refrigerant/coolant and transfer it through the system for building cooling.
Cooling Towers
Reject heat from condenser water by moving heat out of the water and into the air.
Many facilities use both as part of a larger commercial HVAC system—and both benefit from routine service.

Why Winter Is a Smart Time to Schedule Service
Cooler months are often the best time to schedule tower cleaning and chiller inspections because systems typically operate less than they do in peak summer demand. That means:
- Less disruption to tenants/operations
- Faster access to equipment
- Time to correct issues before peak season
- Reduced risk of surprise summer failures
The 3 Core Maintenance Items That Protect Your System
Descaling
Mineral buildup (scale) restricts heat transfer and can increase energy use while reducing cooling performance. Descaling helps restore efficiency and protect major components.
Tube / Coil Cleaning
Condenser tubes and heat exchanger surfaces can accumulate algae, slime, scale, and debris. Regular cleaning improves heat rejection and reduces strain on the system.
Inspections
Annual inspections help catch small issues—before they become emergency shutdowns. We check for wear, corrosion, abnormal vibration/noise, electrical issues, leaks, airflow problems, and waterflow problems.
Cooling Tower Water Quality & Health Protection
Cooling tower water systems can develop biological growth if not managed properly. Routine maintenance and water quality control help reduce risk and support safer operation.
We coordinate maintenance recommendations and service actions to support system cleanliness and performance.
