HVAC & Refrigeration Maintenance (Primary Focus) • Execute daily operational checks, preventive maintenance (PPM), and troubleshooting on chilled water systems (AHUs, FCUs, FAHUs, VAV units) and split/VRF air conditioning systems. • Clean and service evaporator/condenser coils, air filters, condensate drain lines, belts, strainers, and blowers to ensure maximum indoor air quality and cooling performance. • Diagnose cooling issues, refrigerant leaks, compressor failures, motor burnouts, and electrical control faults on HVAC units. • Monitor ambient temperature controls, air balances, and thermostats across tenant zones to fulfill SLA comfort standards. • Address high-humidity risks, coil corrosion, and moisture buildup. 2. General Electrical Maintenance • Perform routine inspections of Main Distribution Boards (MDBs), Sub-Distribution Boards (SMDBs), DBs, and control panels. • Repair and replace faulty switches, breakers, relays, contactors, interior/exterior lighting, and ballast/LED drivers. • Support preventive maintenance checks on emergency power systems, including UPS units and standby diesel generators. 3. Plumbing & Drainage Maintenance • Inspect, maintain, and repair fresh water supply systems, booster pumps, sump pumps, flush valves, and sensor taps. • Clear blockage in drainage lines, maintain storm-water drains, and service domestic water tanks and piping networks. • Inspect piping insulation, valves, and fittings for leaks, condensation, or sea-air corrosion. 4. Building Management & Emergency Systems Support • Assist the engineering team with localized sensor checks for the Building Management System (BMS). • Perform routine visual checks and minor repairs on Fire Fighting pipes, valves, sprinkler lines, and emergency equipment in accordance with Omani Civil Defence guidelines. 5. Site Safety & Work Requests • Complete assigned daily maintenance work orders via the CAFM/CMMS mobile application within target SLA timelines. • Adhere strictly to Health, Safety, and Environment (HSE) protocols, using proper Personal Protective Equipment (PPE), Lock-Out/Tag-Out (LOTO) procedures, and working safely at heights.
