Industrial & Commercial HVAC Services in Dubai & UAE
Chilled water plants, air handling, DX systems and ductwork — designed, installed and commissioned by engineers who build for this climate.
Chillex Technical Services LLC specialises in industrial and commercial HVACR design, engineering and construction. Our engineers and technicians combine design knowledge with hands-on construction experience — which is why our drawings survive contact with a live site.
The result is cooling that is accurate on capacity, honest on running cost, and finished on schedule.
HVACR Design & Engineering
We take an active, forward-looking approach to design and construction, because most cost overruns start as a miscalculation nobody caught early. Our industrial and commercial HVAC design and construction engineers have years of collective experience specific to the Middle East's extreme climate, and our engineering team is equipped to relay each project's design to field workers — so what gets built is what was designed.
That combination of construction experience, design knowledge and problem-solving lets us work through unforeseen site conditions without derailing the programme, which keeps the overall project cost down.
Our engineering consulting division also helps clients optimise facilities investment and solve performance problems that have defeated others. We design and implement strategies and systems that deliver maximum efficiency, measurable cost savings and a longer equipment lifecycle — and we carry out the commissioning and retro-commissioning needed to confirm you are actually getting the benefits your system was designed to provide.
Central Chilled Water Systems
We have professional expertise across all major chiller types — reciprocating, centrifugal and absorption. Chillers distribute cooling evenly and comfortably through large indoor spaces, and when they are selected and controlled properly they do it economically.
Our technicians are trained to design, install, service and repair a wide range of chiller systems, and we offer commercial HVAC maintenance plans that keep your plant running without interruption.

DX Cooling System Installation
We supply and install every common type of direct expansion system, matched to the space and the duty rather than to whatever is on the shelf.
VRF / VRV systems
Multi-zone control for offices, hotels and mixed-use buildings.
Ducted split systems
Concealed cooling for villas, retail and commercial fit-outs.
Packaged units
Self-contained cooling for standalone and industrial buildings.
Split & floor-mounted
Targeted cooling for smaller spaces and technical rooms.
Cassette units
Ceiling-mounted distribution for open-plan areas.
Window units
Economical cooling for small-scale applications.
FAHU / AHU with condensing unit
Fresh air and treated air for process and occupied spaces.

Tell us the space, the load and the budget. We'll specify it properly.
Ductwork & Air Distribution
Air distribution decides whether a well-selected system actually delivers comfort. We fabricate and install GI and MS ductwork, along with insulation, grilles, diffusers, dampers and fire dampers, and we balance the system on completion so every zone gets the airflow it was designed for.
- GI and MS ductwork fabrication and installation
- Duct insulation and cladding
- Grilles, diffusers and dampers
- Airflow balancing and distribution correction
Maintenance & Retro-Commissioning
If your building is cooling unevenly, running up an energy bill nobody can explain, or has never quite performed as designed, the fault is usually recoverable without replacing the plant.
- Annual maintenance contracts with scheduled preventive servicing
- Chiller inspections, performance measurement and efficiency reporting
- Retro-commissioning of underperforming existing systems
- Water balancing and airflow rebalancing
- Electrical circuit testing and control fault-finding
- Refrigerant leak detection and repair
- 24/7 emergency breakdown response
Let's Look at Your System
New installation, upgrade, or a plant that has never performed as designed — we'll survey it and tell you plainly what it needs.
