AFTER-SALES SERVICES, TECHNICAL SERVICE AND PERIODIC MAINTENANCE SERVICES
As ASROYAL, we not only provide project design, engineering, and installation services for mechanical installation and HVAC systems, but also offer comprehensive after-sales services, technical support organization, and periodic maintenance programs that ensure maximum system performance throughout the entire operational life cycle. Today, HVAC systems represent high-value technical investments, and without regular maintenance, increased energy consumption, capacity losses, equipment failures, and operational interruptions may occur.
For this reason, we implement professional maintenance programs for air handling units, chiller systems, VRF systems, fan coil units, ventilation systems, fire protection systems, car park ventilation systems, smoke extraction systems, pressurization systems, and building automation systems. Our maintenance services are not limited to responding to failures after they occur; they are designed to analyze system performance, improve energy efficiency, extend equipment life, identify potential failures in advance, and ensure operational continuity.
HVAC PERIODIC MAINTENANCE SERVICES
Within the scope of our periodic maintenance services, all HVAC systems are thoroughly inspected. Air handling units, fan coil units, VRF systems, chiller plants, exhaust fans, jet fans, ventilation fans, and automation systems are examined according to predetermined maintenance schedules.
During maintenance operations, the following procedures are carried out:
• Inspection and replacement of filters • Chemical cleaning of coils • Fan motor inspections • Bearing and support inspections • Belt and pulley system inspections and adjustments • Tightness checks of electrical connections • Contactor and thermal protection inspections • Sensor calibrations • Automation system testing • Vibration analysis • Noise level measurements • Airflow measurements • Duct leakage inspections • Energy consumption analysis
These activities help maintain system performance close to its original operating condition while significantly reducing energy costs.
AIR HANDLING UNIT SERVICE AND MAINTENANCE
Air handling units are among the most critical components of HVAC systems. Over time, filter contamination, dust accumulation on coil surfaces, fan imbalance, belt loosening, and automation issues may occur.
Within the maintenance services performed by ASROYAL maintenance teams, the following operations are carried out:
• Pre-filter, bag filter, and HEPA filter inspections • Filter replacement • Cooling and heating coil cleaning • Disinfection of drain pans • Humidification system maintenance • Fan balance inspections • Belt tension adjustments • Bearing lubrication • Testing of damper motors • Pressure sensor calibration • Verification of automation sequences • Airflow measurements
Especially in hospitals, clean rooms, and food production facilities, regular maintenance of hygienic air handling units is critical for both health and production quality.
CHILLER SYSTEM SERVICE AND MAINTENANCE
Chiller systems are centralized cooling systems with high investment costs. In chiller plants that are not regularly maintained, energy consumption can increase significantly and compressor failures may occur.
Our maintenance services include:
• Compressor performance analysis • Refrigerant inspections • Refrigerant leak testing • Condenser cleaning • Evaporator cleaning • Oil level inspections • Electrical panel inspections • Contactor and drive inspections • Sensor calibrations • Water flow measurements • Energy analysis • Automation system inspections
These procedures help maintain equipment efficiency and prevent unexpected breakdowns.
VRF AND VRV SYSTEM SERVICE
VRF systems are high-technology products equipped with advanced electronic control infrastructures. Maintenance services performed on these systems are essential for preserving equipment performance.
Our service operations include:
• Indoor unit filter cleaning • Fan cleaning • Evaporator cleaning • Outdoor unit condenser cleaning • Refrigerant pressure checks • Refrigerant leak testing • Communication infrastructure inspection • Electronic board inspections • Sensor inspections • Automation connection inspections • Energy consumption analysis
These procedures help maintain VRF system efficiency and extend equipment lifespan.
VENTILATION SYSTEM MAINTENANCE AND CLEANING SERVICES
Over time, dust, bacteria, particles, and grease can accumulate inside ventilation duct systems. This not only increases energy consumption but also negatively affects indoor air quality.
Within the maintenance services provided by ASROYAL, the following procedures are performed:
• Air duct cleaning • Grille cleaning • Diffuser cleaning • Internal duct inspection and imaging • Fan maintenance • Motor inspections • Duct leakage testing • Airflow measurements • Filter replacement • Indoor air quality measurements
These procedures preserve system hygiene and support occupant health.
FIRE PROTECTION SYSTEM SERVICE AND MAINTENANCE
Fire protection systems are critical safety systems that must remain operational at all times. Regular maintenance is mandatory to ensure that these systems function flawlessly during emergencies.
Our maintenance services include:
• Fire pump testing • Jockey pump inspections • Diesel fire pump testing • Sprinkler line inspections • Valve position inspections • Hydrant system inspections • Pressure measurements • Flow testing • Alarm valve testing • Fire scenario simulations • Pressurization fan testing • Smoke extraction system inspections
These procedures ensure that fire safety systems remain fully operational and ready at all times.
24/7 TECHNICAL SERVICE AND EMERGENCY RESPONSE
ASROYAL's technical service organization is designed to provide rapid response to potential failures. Our expert technical personnel respond quickly to mechanical, electrical, and automation-related failures occurring within HVAC systems.
Fault diagnosis, spare parts supply, equipment replacement, performance improvements, and system optimization are carried out by our professional teams. Our goal is not only to repair failures but also to implement permanent solutions that prevent recurrence.
WHY ASROYAL AFTER-SALES SERVICES?
ASROYAL’s after-sales service philosophy is based on preventive maintenance, predictive maintenance, energy efficiency management, and rapid technical support. Through our regular maintenance programs, HVAC system energy consumption is reduced, equipment life is extended, operational continuity is maintained, and maintenance costs for investors are minimized.
With our expert engineering staff, experienced technical service team, and professional maintenance organization, we ensure that your mechanical systems operate safely, efficiently, and sustainably at all times.
