As warmer weather approaches, now is the ideal time to prepare your facility’s cooling systems for the summer season. Performing early start-up inspections and operational checks can help identify potential problems before peak cooling demand arrives, reducing the likelihood of unexpected downtime, costly emergency repairs, and occupant discomfort.
A proactive approach to seasonal maintenance also helps improve system efficiency, extend equipment life, and ensure your building is ready to handle rising temperatures.
Begin with a Full System Start-Up
Before summer begins, turn on all cooling-related equipment and verify that each system is operating correctly. Running systems ahead of the season allows facility staff to identify issues early while there is still time to make adjustments or repairs.
This includes checking:
- Chillers
- Cooling towers
- Rooftop units (RTUs)
- Pumps and associated cooling equipment
- Other critical cooling system components throughout the facility
Use Flow Monitoring to Verify Performance
One of the most effective ways to evaluate cooling system performance during start-up is by using a portable ultrasonic flow meter. These tools allow operators to measure system flow without cutting into piping, making them ideal for troubleshooting and seasonal verification.
Key measurements to review include:
- Chiller flow rates
- Chilled water supply temperatures
- Chilled water return temperatures
Monitoring both flow and temperature data can help confirm that systems are operating within expected ranges and delivering adequate cooling capacity.


Identify Problems Before Peak Demand
Seasonal start-up testing provides an opportunity to detect issues that may otherwise go unnoticed until the hottest days of the year. Irregular flow readings, temperature imbalances, or reduced performance can indicate underlying system problems that should be addressed before summer demand increases.
By preparing early and verifying system operation ahead of time, facilities can improve reliability, maintain occupant comfort, and reduce the risk of emergency service interruptions during peak cooling season.
