Our Repair Process

1) Intake and safety review: confirm site access, sequences, and lockout/tagout.
2) Root‑cause diagnostics: electrical, refrigerant, mechanical, and control pathways.
3) Findings and options: we present a clear, prioritized plan with pricing.
4) Precision repair: OEM parts, proper torque, evacuation, charging by weight and subcool/superheat, and BMS coordination.
5) Verification: trend logs, delta‑T, approach temps, amperage, and staging logic.
6) Handover: documentation, recommendations, and preventive steps to protect uptime.

Preventive Maintenance & Retrofits

Reliable comfort and healthy indoor air start with a stable chilled‑water plant. We build maintenance programs around your loads, run hours, and water chemistry—reducing emergency calls and extending equipment life. When it’s time to modernize, we implement targeted retrofits such as VFD optimization, high‑efficiency fan motors, improved control sequences, and advanced alarming for earlier intervention.

Industries We Serve

• Office and mixed‑use commercial properties
• Healthcare and labs
• Hospitality and entertainment venues

Why Healthy Air Starts with a Reliable Chiller

Your chiller underpins ventilation, humidity control, and occupant comfort. When capacity or stability slips, IAQ and productivity suffer. Our mission—healthy air at home and at work—drives every repair and optimization we perform, keeping temperatures stable, humidity managed, and energy use in check.
