Who needs an operation and maintenance contract?
- 1
A facility without an in-house team
Hotels, factories and government buildings need someone daily to start chillers, watch pumps and log readings. Without a specialist team, a small fault grows before anyone notices.
- 2
A facility with repeated breakdowns
Repeated breakdowns usually point to missed preventive work: a blocked filter, a compressor running under load, a worn pulley in an AHU. A contract catches these causes before they become full failures.
- 3
A government or hotel project that requires records
Some government and hotel clients require operating logs and regular maintenance reports. We produce these on schedule and keep them available whenever you need them.
Who it's for
Managing a hotel where the HVAC plant runs all day
We handle daily operation of chillers, AHUs and pumps, and produce the reading logs and reports your hotel management requires.
Ask on WhatsAppRunning a factory where an HVAC stoppage halts production
We carry out preventive maintenance on compressors, coils and valves on schedule so your production line is not stopped in Jeddah's summer, and we repair any fault as soon as it appears.

How we work
How we work
- 1
Site survey and plant assessment
We visit the facility and record all HVAC equipment, assessing the condition of each unit before signing, because the scope depends on what the survey finds.
- 2
Agree scope and schedule
We set the preventive maintenance schedule with you, define the daily operating tasks and each party's responsibilities, and agree the format and frequency of reports.
- 3
Start operations and preventive work
Our team handles daily operation and carries out preventive work on schedule: cleaning coils, inspecting compressors, testing valves and manifolds, and logging readings each round.

What sets this district apart
Al Mulaisa has relatively modern buildings, hotels and multi-storey residential blocks with commercial ground floors, all relying on complex central chilling systems that link many parts together. In Jeddah's long summer and coastal humidity, any single fault cascades through the whole plant, making daily preventive and corrective maintenance essential to keep the service unbroken and occupants comfortable.
Al Mulaisa lies in south Jeddah, a district of modern hotels and large residential blocks with complex central chilling systems.
Most large buildings here run on central chillers or air handling units connected by a duct network and unified automation controls.

FAQ
Questions about Operation & maintenance contracts
Do you handle plant operation as well as maintenance?
We cover both. Our team operates the plant daily: monitoring circuit pressures, water temperatures and flow rates, logging control-panel readings, and adjusting settings to match the load. Alongside daily operation, the contract includes preventive and corrective maintenance, with regular reports submitted to facility management.
What is the difference between preventive and corrective maintenance in your contract?
Preventive maintenance means inspecting components while they are still running: cleaning AHU coils, checking pump belts and fan bearings, verifying copper-pipe connections, and testing condenser and evaporator performance. Corrective maintenance starts when an actual fault is found, such as a tripping breaker, a degraded capacitor or a circuit leak, and the goal is to restore full plant performance.
Can you work on different brands of equipment in the same facility?
Yes. Many facilities combine equipment from several manufacturers on a single network. Our team works with Carrier, YORK, General, Midea, Gree and Smart Gold equipment within one unified operating system. When a contract covers multi-brand equipment, the initial site survey sets the specific procedures for each unit.
What happens when a worn part is found during a preventive maintenance round?
The technician records the finding in the inspection log and notifies the facility supervisor immediately. The extent of the damage and its effect on the rest of the plant is assessed, then the part is replaced or repaired under corrective maintenance before the fault develops and disrupts operation. The full incident is entered in the visit report.
What happens when a worn part is found during a preventive maintenance round?
We record the finding immediately in the round log and inform facility management of the part and the cause of the wear. After approval we replace the part and record it in the maintenance report. The final decision stays with you, and identifying the right part depends on the unit specifications noted in the survey.
What is the difference between a contract and repair-when-broken?
A contract includes planned inspection and preventive maintenance with detailed records, so we spot problems before they cause a shutdown. Repair-only leaves your plant vulnerable to sudden failures during peak summer.
Are duct and chiller coil cleaning included in the contract?
Yes, duct cleaning, chiller coil maintenance and pump servicing are part of a full contract, and every visit and task is recorded in clear reports.
Coastal humidity in Al Mulaisa affects the chillers, how do you handle this?
High humidity speeds corrosion and mould on coils, so we clean the chiller coils on a regular schedule and inspect tube seals and joints for leaks.
How many technicians will be assigned to our plant?
It depends on the plant size and contract scope; we assign a team based on the number of chillers, ducts and units, all written into the agreement.
