Preventive Maintenance & Coil Care
Specification: Quarterly & Custom Annual Agreements
Scheduled coil cleaning, tube brushing, and multi-point inspections to preserve peak thermodynamic efficiency.
Engineering Scope & Overview
Preventive maintenance is the single highest-return investment a facility manager can make. Regular chemical coil cleaning and tube brushing removes scale, biological buildup, and particulate fouling, preventing heat transfer degradation and reducing compressor lift power demand.
WMI Field Protocol & Certified Best Practices
- Chemical de-scaling and bio-enzyme condenser/evaporator coil treatments
- Refrigerant moisture and acid testing with oil sampling analysis
- Electrical terminal torque checks and infrared thermographic scanning
- Belt tensioning, bearing lubrication, and air filter differential pressure verification
Frequently Asked Questions
- How often should commercial condenser and evaporator coils be cleaned in Southern California?
- Due to urban particulate matter, pollen, and dry dust, high-tonnage condenser coils should be chemically washed and cleaned at least semi-annually, with quarterly inspections during heavy summer runtime.
- What is included in an annual chiller preventive maintenance service?
- Annual chiller service includes head removal, rotary tube brushing, eddy current testing of heat exchanger tubes, compressor oil analysis, safety relief valve checks, and sensor calibration.
- Do customized service agreements lower total facility operating costs?
- Yes. Regular preventive maintenance prevents up to 95% of catastrophic compressor failures and reduces annual facility electrical consumption by 15% to 25% by preventing scale fouling.
