Larger buildings rely on chillers, cooling towers and air handling units that need specialist attention. HILLS AC Services maintains screw, scroll and centrifugal chillers, services cooling towers and hydronic pipework, and overhauls AHU and FAHU systems for hotels, offices and industrial premises across Dubai. Our engineers work to a planned maintenance schedule that keeps plant rooms running efficiently and avoids unplanned downtime.
Every price is confirmed in writing after an inspection or site survey, before any work begins.
Chiller & Cooling Tower Maintenance
Screw, scroll and centrifugal chiller servicing, cooling tower descaling, fill-pack cleaning and water treatment for plant rooms and hotels.
Plant work scheduled around occupancy, with readings taken and recorded rather than described. Heat-transfer surfaces, control settings and water quality are checked together, because efficiency loss on this equipment is gradual and invisible until someone measures it. Reports are issued in the format facilities managers and inspectors expect, and we work evenings or shutdown windows where occupants cannot be disrupted.
Air handling unit overhaul covering belts, bearings, blower balancing, filter racks and fresh-air intake maintenance.

Chemical dosing for open and closed loop systems to prevent scaling, corrosion and legionella growth.
Filtration check, chemical balance and physical cleaning on every visit, with pump, filter and chiller condition recorded. Water that keeps going cloudy despite correct dosing is almost always mechanical — a filter past its life or a pump not turning the volume over. We tell you which it is rather than selling more chemicals. Summer needs a tighter interval than winter, and we will say so.
Yes, our engineers service screw, scroll and centrifugal chillers, including compressor checks, oil analysis and tube brushing.
Most commercial cooling towers in Dubai benefit from quarterly descaling and water treatment given the heat and mineral content of the water supply.
Yes, planned maintenance contracts are available for hotels, offices and industrial premises, with priority call-out included.
Yes. Cold rooms, display chillers and commercial freezers are prioritised because stock is at risk. Call rather than message if temperature is already rising.
Usually only briefly. Where extended downtime is unavoidable we schedule outside trading hours and tell you in advance so stock can be moved.
Tell us the property and we will confirm a fixed written price after an inspection.
Why It Matters
Why hvac & chiller services is worth doing properly
Refrigeration failure is a stock loss and a compliance event at the same time. In a UAE summer the margin between a working system and spoiled product is measured in hours, and food safety and pharmacy inspections require documented evidence that temperature was held throughout.
The most common cause we attend is entirely preventable: a condenser coil loaded with dust so the system runs continuously without reaching temperature. It draws more power, wears the compressor, and eventually fails on the hottest day of the year, which is when it is least convenient and most expensive.
Why HILLS
We inspect before quoting, and the written price we give is the price you pay. No revision once the work has started, and no discovery of additional scope on the day. Where a job falls outside what we do, we say so rather than taking it on.
Every job is documented. Photographs before and after go to your WhatsApp the same day, and certificates are issued where one is needed for inspection. The equipment is proper trade kit — HEPA-filtered extraction, calibrated instruments and cameran inspection — because diagnosis before parts is what keeps a quote honest.
We have worked on Dubai cooling since 2021, across 67 communities and everything from a single split unit in a JVC apartment to chiller plant rooms and commercial kitchen extract systems. That range matters, because it means the person who attends has seen your system type before.
