Home / AC Refrigerant Gas Leak Repair
Specialist ServiceA unit that cools weakly, ices up, or has stopped cooling altogether is very often a refrigerant leak rather than a failed compressor. HILLS AC Services traces the leak, repairs the pipework or fitting, and tops up the refrigerant to the correct charge, rather than just topping up gas that will leak out again in a few weeks.
Every price is confirmed in writing after an inspection, before any work begins.
Electronic leak detection to find exactly where refrigerant is escaping before any repair work starts.
We trace the leak before adding anything. Electronic detection and, where needed, nitrogen pressure testing, because a system topped up without a repair loses the charge again within weeks. Once the repair holds, the system is evacuated and recharged to the manufacturer's weighed specification rather than guessed by gauge pressure. That distinction is the difference between a fix and a recurring bill.
Brazing or fitting replacement at the leak point, sized to the system.
We inspect before quoting, and the written price is what you pay. The work is documented with before-and-after photographs sent to your WhatsApp the same day, and a certificate where one is needed for inspection. Where a job falls outside what we do, we tell you rather than taking it on.
Recharge to the manufacturer's correct refrigerant charge once the leak is fixed.

Topping up gas without finding and fixing the leak first just delays the same problem by a few weeks or months. We always find and repair the leak before recharging, so the fix actually holds.
Detection and a straightforward fitting repair usually take 2 to 4 hours; a leak inside sealed pipework can take longer and we'll quote that after inspection.
No. The inspection and the written quotation are , and the price is fixed before any work starts. You are not committed to proceeding.
Common consumables and frequently failing components, yes. Anything model-specific we source and return, usually within 24 to 48 hours, and we tell you the cost before ordering.
Yes. Workmanship is warranted, and any part we supply carries its manufacturer warranty. The terms are written on your invoice rather than promised verbally.

Supply, positioning, refrigerant or chilled-water piping, electrical connection and commissioning, coordinated with whoever else is working on the ceiling. We survey before quoting because unit sizing and pipe runs are where installations go wrong, and an undersized system cannot be corrected afterwards without replacing it. Commissioning readings are recorded and handed over, so you have evidence the system performs to specification on day one.

156 Dubai communities, each with its own page.
Tell us the property and we will confirm a fixed written price after an inspection.
A cooling fault in Dubai is not an inconvenience, it is a habitability problem. Peak summer ambient temperatures mean an unoccupied fault becomes a damaged property, and equipment running at full load in 45°C-plus conditions fails differently from equipment in a temperate climate. Components that would last a decade elsewhere are working near the edge of their design envelope here.
Most of the expensive failures we attend were avoidable. A refrigerant leak left unaddressed destroys a compressor. A failing capacitor left running burns out a motor. The repair that was needed six months ago is almost always a fraction of the repair that is needed now.
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.
Inspection first, fixed price, honest advice.
