Featured Case Studies

Three of our most demanding long-running engagements — each one chosen because the brief, environment and operational constraints were unusually tight.

Sunway Medical Centre — Precision Cooling for Critical Care

Healthcare · Bandar Sunway · Multi-year engagement

Scope of work. Mavis Eco Cool was engaged to provide preventive maintenance and emergency response across cassette and ducted HVAC systems serving operating theatres, ICU corridors, lab spaces and outpatient consultation rooms. Each zone has different air-quality and humidity tolerances, so the maintenance plan is split by criticality and rebuilt every six months. The scope includes filter change, coil chemical wash, drain pump testing, refrigerant pressure checks and on-call emergency aircon repair on a 24-hour rota.

Challenges and outcome. Hospital HVAC cannot be shut down without coordination — patients depend on stable temperature and humidity. We work in pre-agreed time windows around theatre schedules, and run noise-sensitive jobs during off-peak hours. Over the engagement we have delivered zero unplanned downtime in critical zones, brought several long-running ducted units back to original cooling capacity, and handed over a written maintenance log that supports the hospital's compliance reporting.

Genting Highlands Resort — Resort-Wide HVAC Across Altitude & Humidity

Hospitality · Pahang · Resort properties

Scope of work. Cooling and dehumidification work across multiple resort properties — guest rooms, F&B outlets, back-of-house service corridors, plant rooms, and selected commercial cooling tower assets. The scope spans cassette servicing, split-unit chemical wash on guest-room rotation, drain and condensate work, refrigerant pressure rebalance, and project work during low-occupancy windows.

Challenges and outcome. Genting's altitude and high ambient humidity put real stress on coil cleanliness and drainage — units that would last 18 months without service in PJ start dripping after 9 months up there. We adjusted the maintenance frequency and chemical formulation to suit, switched some units to drain-pump assist, and standardised the spares list so emergency response is faster. Guest complaints about unit noise and condensation dropped substantially after the first full rotation, and the resort now plans its annual HVAC budget against our condition reports.

Klang Port Authority — Industrial Cooling in a 24/7 Logistics Environment

Industrial · Klang · 24/7 logistics

Scope of work. Maintenance and refurbishment work across cooling tower assets, control rooms, server rooms and operational office space serving Klang's port operations. Activities include cooling-tower chemical dosing programmes, biocide treatment, fan motor replacement, fill-pack inspection, and ducted HVAC servicing for control-room reliability.

Challenges and outcome. The site runs 24/7 — there is no convenient downtime window. We coordinated cooling-tower strip-down and re-commissioning across long-weekend shutdown slots, deployed redundant temporary cooling for control rooms during the changeover, and delivered every scope item without interrupting port operations. The towers are now running at restored efficiency with documented condition baselines, and Mavis Eco Cool remains on call for emergency aircon repair across the operational footprint.
