FixFast LLC keeps commercial and industrial cooling systems running across Dubai and the wider UAE. OEM-trained HVAC engineers, 24/7 emergency response, AMC packages for every facility size — from a single air-cooled unit to full district cooling plants.
FixFast LLC is a Dubai-based HVAC and cooling systems engineering company. For 15+ years we have kept commercial and industrial chillers running across the emirate — from single-building rooftop units in Business Bay to full water-cooled plants in JAFZA warehouses and district cooling loops in Dubai South. Our engineers are OEM-trained, licensed under Dubai Municipality, and equipped with the diagnostic instruments needed to identify faults on Trane, Carrier, York, Daikin, Blue Star, McQuay and every other major brand operating in the UAE.
If you are searching for chiller repair Dubai, chiller repair near me, or a partner for a multi-site AMC portfolio, this page tells you exactly what we do, how we work, and how quickly we can be at your facility.
Our engineering team delivers end-to-end HVAC services covering every aspect of commercial and industrial cooling — from single-visit emergency repairs through multi-site AMC portfolios and full chiller replacement projects.

Chillers rarely fail without warning. In the two or three weeks before a full breakdown there is almost always a shift in something an experienced technician would notice — a compressor that starts drawing more current than usual, a delta-T that has quietly narrowed, an alarm log that shows the same fault clearing itself every few days. Recognising these signals early is the difference between a scheduled repair and a middle-of-the-night emergency call. Here are the faults our engineers see most often across Dubai commercial and industrial sites.
Setpoints are still met but the compressor runs longer to hold them. Building occupants may not notice for weeks, but the operations team sees the electricity bill climb and the return water temperature slowly rising. The usual culprits are fouled condenser tubes, scaled evaporator surfaces from poor water treatment, a partially blocked expansion valve, or refrigerant charge that has quietly dropped through a slow leak. Any of these can be identified with a proper performance test against the design curve. The catch is that someone with the right instruments actually has to do the test.
Dubai’s temperature swings and constant vibration on rooftop plants make joint failures and flare-fitting leaks a routine finding. On a screw or centrifugal unit, a leak of a few kilograms per year is easy to miss until suddenly the machine trips on low pressure in the middle of a summer afternoon. We do full electronic leak detection on every AMC visit, and we always repair the leak before we recharge. Topping up a leaking system is expensive theatre, not maintenance.
A compressor that starts and stops every few minutes is either responding to a control-side problem (thermostat drift, sensor failure, BMS logic issue) or a mechanical one (worn bearings, oil starvation, or an internal electrical short). The two need very different responses. Short-cycling left unresolved for weeks can turn a AED 3,000 sensor replacement into a AED 40,000 compressor rebuild. This is the single most expensive fault to ignore.
The chiller is fine, but no cold water is reaching the AHUs on the top floors. That points at the chilled water side. A failing pump seal, a stuck balancing valve, air trapped in the high points of the loop, or a variable-speed drive that has lost its control signal are all common culprits. On older buildings we also see corroded or scale-blocked pipework that needs flushing before the system can move design flow again. Solving flow issues is often 80% of restoring cooling performance without touching the chiller itself.
Modern chillers are as much a control system as a mechanical machine. Erratic alarms, sensors reading out of range, VFDs faulting on the same code every morning, or a BMS integration that lost communication after a firmware update. These all need someone who can read PLC logic, not just swap parts. Our engineers hold OEM controls certifications for the major brands, which means we can actually diagnose the software layer rather than replacing hardware in the hope something sticks.
Our on-call engineers respond to Dubai emergencies within 2 hours, day or night, seven days a week.
From centrifugal Trane and York units in downtown towers to screw compressor Daikin and Blue Star systems in industrial facilities, our engineers work across the full brand landscape of the Dubai market.
Our engineers hold factory training and service certifications for every major chiller manufacturer operating in the UAE.
An Annual Maintenance Contract is not paperwork. It is the difference between predictable cooling and a series of expensive emergencies. Our AMC packages are built around what the site actually needs: chiller type, capacity, operating hours, criticality of cooling to the business, and whether you already have an in-house facilities team we are supporting or replacing. Below are our four standard tiers. Every proposal we send begins with a site survey, so the final contract fits your equipment exactly rather than a generic template.
A few things worth understanding before you sign any AMC in Dubai. First, insist that the contract lists exactly what the technician does on each visit, not just how often they turn up. A cheaper AMC that involves a 20-minute walk-through and a signed sheet is worse than no contract at all. It gives you a false sense of coverage. Our visit checklists are attached to every proposal, so you know exactly what work is being done and can hold us to it.
Response SLAs matter more than the maintenance schedule. When a compressor trips at 2 AM in July, what matters is whether the on-call engineer can be at your site inside two hours, not whether their quarterly visit was on time. Our SLA response times are in writing on every AMC, backed by liquidated damages if we miss them. Almost nobody else in the Dubai market offers that.
Parts pricing needs to be transparent up front. Some AMC providers price the contract low and make it back on marked-up spare parts when something breaks. We publish our parts markup schedule as an annex to the contract so you never have to argue about a compressor price in the middle of an emergency. Genuine OEM parts sit at manufacturer list price plus a fixed handling fee. That is it.
Reporting and traceability. Every visit generates a signed digital report with photos, meter readings and a compliance checklist. Reports go to whichever email addresses you nominate, and we keep the full history for the life of the contract. If your facility ever needs to demonstrate maintenance compliance for insurance, DEWA audits, or a building sale, the paper trail is already there.

"Our water-cooled Trane unit tripped on a Friday night just as the restaurant was filling up. FixFast’s on-call engineer was on site in 90 minutes, isolated a control-side fault, and had cooling back to the dining floor before the second seating. Signed a comprehensive AMC the following week."
"We manage a portfolio of eight commercial towers across Business Bay and DIFC. Consolidating chiller AMC with FixFast gave us one point of contact, one monthly report per site, and a genuine 2-hour SLA on the enterprise contract. Response has been reliable for over two years now."
"Our pharmaceutical warehouse in JAFZA needs uninterrupted process cooling. FixFast’s engineers understood the compliance requirements immediately, delivered a full-coverage AMC with signed maintenance records, and have kept us within tolerance for eighteen months. Recommended for any regulated site."
