Home / AC Gas Refill & Top-Up
Specialist ServiceIf your aircon needs regular gas top-ups, it has a leak. Refrigerant is a sealed charge, not a consumable, so a system losing it will keep losing it. HILLS AC Services traces the leak, repairs it, then recharges to the manufacturer's exact weight for R22, R410A and R32 systems — rather than simply adding gas that will escape again within weeks.
Every price is confirmed in writing after an inspection, before any work begins.
Electronic detection and, where needed, nitrogen pressure testing to find exactly where refrigerant is escaping.
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.

R22 is being phased out. We advise honestly whether retrofitting or replacing is the better economic call for your unit.
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.
Never, on a healthy system. Refrigerant sits in a sealed circuit and is not consumed. If yours needs topping up annually, it is leaking, and the leak is the actual repair. Anyone selling you a routine yearly gas top-up is selling you a symptom.
It depends on the refrigerant type and how much has been lost. R32 and R410A are priced differently from legacy R22. We confirm a fixed figure after the inspection, before starting.
R22 is being phased out under international agreement, so supply is shrinking and prices are rising. For an older unit still running R22 we will tell you honestly whether continuing to service it or replacing it works out cheaper over the next few years.
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.

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, then a fixed written price before any work starts.
