Who We Serve
We repair and maintain commercial AC systems for:
- Offices and co-working spaces
- Retail units and shopping mall tenants
- Restaurants, cafes, and cloud kitchens
- Clinics and small medical facilities
- Warehouses and light industrial units
- Residential and commercial buildings on chilled water or district cooling
- Facilities management companies needing a reliable subcontractor
We understand that commercial clients need fast, minimally disruptive repairs — our technicians are equipped to diagnose most faults on the first visit.
Systems We Repair
- VRF/VRV systems — multi-zone systems common in offices and mid-to-large commercial spaces
- Cassette AC units — ceiling-mounted units common in retail and restaurants
- Chillers — for larger buildings and facilities using chilled water
- Fan Coil Units (FCUs) — used in buildings connected to district cooling
- Package and ducted rooftop units — common in warehouses and standalone retail
VRF/VRV System Repair in Dubai
VRF (Variable Refrigerant Flow) and VRV systems allow multiple indoor units to run off a shared outdoor condensing unit, which is efficient — but means a single fault can affect several zones at once. Common issues we repair include:
- One or more indoor units not cooling while others work normally
- Refrigerant leaks in the piping network
- Outdoor unit compressor faults
- Communication errors between indoor and outdoor units
- Control board and remote controller faults
VRF diagnosis requires checking system-wide refrigerant pressure and communication signals, not just the affected unit — our technicians are trained specifically on multi-zone diagnostics. → Full VRF/VRV repair guide
Cassette AC Repair for Offices and Shops
Ceiling cassette units are common in retail stores, restaurants, and offices for their discreet, even airflow. We repair:
- Weak or uneven airflow
- Water leaking from the ceiling unit
- Louver (flap) motor faults
- Noisy operation
- Remote and control panel issues
Because cassette units are recessed into the ceiling, repairs are typically done via the unit’s access panel without disturbing the surrounding ceiling. → Cassette AC Repair Guide
Chiller Repair and Servicing
Chillers serve larger buildings and facilities, cooling water that’s then circulated to fan coil units throughout the property. We provide:
- Chiller fault diagnosis and repair
- Compressor and pump repairs
- Refrigerant leak detection
- Water treatment and flow issue troubleshooting
- Scheduled preventive maintenance for chiller plants
Chiller work requires specialized technicians — ours are experienced with the air-cooled and water-cooled chiller models common in Dubai commercial buildings. → Chiller Repair and Servicing
Fan Coil Unit (FCU) Problems in Chilled Water Buildings
If your building is connected to district cooling, your unit is most likely a fan coil unit (FCU) rather than a standalone AC. FCUs draw already-chilled water rather than generating cooling themselves, which changes how faults present:
- If the FCU isn’t cooling but the building’s chilled water supply is fine, the issue is usually the FCU’s fan, valve, or filter.
- If multiple units in the building are affected, the issue may be with the chilled water supply itself, which falls under the district cooling provider’s responsibility, not ours.
We diagnose and repair FCU-side issues, including motor faults, control valve failures, and clogged filters or coils. → Full FCU troubleshooting guide | District Cooling Explained

Commercial AC Repair Cost
Commercial AC repair costs vary significantly depending on system type (cassette, VRF, FCU, or chiller), unit size, building access, and whether the work falls under an existing maintenance contract. Because of this range, we assess commercial jobs with a site visit and provide a written quote rather than publishing fixed prices here.
For buildings or businesses with recurring needs, our AMC plans offer predictable, discounted pricing — see maintenance contracts above. For a one-off repair, request a site visit and we’ll confirm pricing before any work begins.

Frequently Asked Questions
Yes, we offer after-hours and weekend appointments for commercial clients specifically to minimize disruption to operations.
Yes, we work directly with FM companies and building management as a maintenance subcontractor, including providing maintenance logs and compliance documentation.
A chiller produces chilled water at a central plant; fan coil units (FCUs) are the individual indoor units in each space that use that chilled water to cool the air. If your FCU isn't cooling but the building's chilled water is functioning normally, the fault is typically in the FCU itself. See our FCU guide.
On a VRF/VRV system, individual zones can fail independently due to a faulty indoor unit, a blocked line, or a communication fault, even while the outdoor unit and other zones work normally. This requires system-level diagnosis rather than just checking the affected unit.
Yes, we set up multi-site AMC contracts with consolidated scheduling and reporting. Contact us to discuss your locations and system types.
Our technicians are experienced with chiller diagnostics and common repairs. For major chiller plant overhauls or replacements, we'll advise if specialist subcontracting is needed and coordinate accordingly.
We prioritize commercial breakdowns affecting occupied offices, retail floors, or kitchens. See our emergency AC repair page for response details.
