At #1 AC Guys, our mission is simple: healthier air and dependable comfort for a healthier life. For commercial facilities that rely on Lennox centrifugal chillers, that mission translates into careful preventive maintenance, tight controls calibration, and a relentless focus on energy performance—without interrupting your operations.

Why proactive centrifugal chiller maintenance matters

• Protect capacity and comfort under peak loads while extending asset life.
• Lower energy spend through optimized lift, approach temperatures, and setpoints.
• Reduce emergency calls and production impacts with predictive insights.
• Support compliance and risk management with documented procedures and test results.
• Improve indoor air quality by stabilizing temperatures and humidity for occupants and processes.

We tailor every maintenance plan to your plant configuration, occupancy profile, and water treatment strategy, aligning routine tasks and testing with your operational calendar.

What’s included in a Lennox centrifugal chiller maintenance visit

• Operational baseline: approach, lift, condenser/evaporator pressures, superheat/subcooling, kW/ton.
• Controls calibration: sensors, safeties, setpoints, sequencing, and trim adjustments for stability.
• Oil and refrigerant care: sampling, analysis, filter/drier inspection, leak screening, and charge verification.
• Vibration and bearings: trend analysis, alignment checks, and coupling inspection to protect the compressor train.
• Heat‑exchange performance: tube inspection and cleaning, fouling assessment, and eddy current testing as needed.
• Electrical integrity: contacts, megger tests, VFD checks, starters, and power quality review.
• Condenser water optimization: tower approach checks, flow verification, and coordination with water treatment.
• Seasonal readiness: start‑up/shutdown procedures, freeze protection, and standby strategies for shoulder seasons.
• Documentation: photos, readings, and action items prioritized by risk, cost, and energy impact.

Where applicable, we service purge components, confirm relief devices are current per code, and coordinate with qualified partners when specialty certifications are required—all to keep your system compliant and dependable.
