With warm weather almost upon us, now is the time to prepare for the transition from heating to cooling operations. A comprehensive spring preparation strategy ensures optimal performance, energy efficiency, and system longevity.
Here is your essential spring checklist:
Basic Maintenance Fundamentals
• Replace filters and clean evaporator coils, condensing coils, and drain pans
• Clean and test cooling towers and water filtration systems
• Flush and blow out chilled water systems and clean strainers
• Service reheat hot water systems
• Perform refrigerant leak detection on all DX systems
Enhanced System Checks
• Inspect and calibrate control sensors and thermostats
• Test and validate all safety controls and interlocks
• Check belt tension and alignment on belt-driven equipment
• Verify proper operation of variable frequency drives
• Inspect electrical connections and components
• Test and validate building automation system (BAS) sequences
Water Treatment and Management
• Test water chemistry in all hydronic systems
• Clean and treat cooling tower fill and basin
• Verify proper operation of chemical treatment systems
• Check condition of tower fill media and drift eliminators
• Inspect and clean all spray nozzles
Energy Optimization
• Take advantage of warm days and cool nights by ensuring economizer cycles are programmed correctly
• Review and optimize start/stop scheduled
• Check and calibrate outdoor air dampers
• Verify proper operation of demand-controlled ventilation
• Update setpoints for seasonal changes
Predictive Maintenance and Specialized Testing
• Document baseline operating parameters
• Perform vibration analysis on critical equipment
• Use thermal imaging to identify potential issues
• Record and trend amperage draws on major equipment
• Monitor bearing temperatures on large motors and pumps
System Performance Verification
• Confirm all systems are operating to design intent
• Verify proper temperature differentials across heat exchangers
• Check cooling tower approach temperatures
• Monitor space temperature and humidity levels
• Review trend logs for irregular patterns.
Remember: A well-maintained system not only saves energy and extends equipment life but also ensures optimal indoor air quality and occupant comfort throughout the cooling season.
