AC Services
AC Gas Refill and Leak Detection in Dubai
Refrigerant does not get used up. If it is low, it went somewhere.
Nitrogen pressure testing to find the leak first, then a precision top up.

Serviced so it lasts the summer
Most AC failures in August were visible in April. A proper service finds them while they are still cheap and while a part is still available.
- Electrical, gas and drainage checked together
- Faults photographed and shown to you
- Written quote before anything is replaced

Diagnosed before anything is replaced
Replacing a part that was not the fault is the most expensive outcome in this trade. We find the cause first and show it to you.
- You see the fault before you approve the fix
- No parts added after the quote
- One team, so no trade blames another

Sized and set up properly
An oversized unit short cycles, never dehumidifies, and leaves a villa cold and clammy. Sizing is done on the room, not on the price list.
- Load calculated on the actual space
- Commissioned and balanced on handover
- Warranty and service record left with you
Before anything is quoted
We look at the property before we put a number on it
A price list cannot see your marble, your ducts, or the wall the afternoon sun hits. So we come and look. A senior member of the team surveys the property, and you receive a written quotation the same day, itemised, with what is included and what is not.
No obligation. If we are not the right company for the job we will say so, and tell you who is.
- 01The survey
We look at the property, not a price list. Usually the same day you ask.
- 02The written quote
Fixed, itemised, and sent the same day. What is included, and what is not.
- 03The work
A named supervisor and a crew you will see again. Our own equipment and materials.
- 04The walkthrough
We walk the property with you before the team leaves. Anything not right is dealt with then.
About this service
What is ac gas refill & leak detection and what does it include?
A top up without a leak test is a repair with an expiry date on it.
An air conditioning system is a sealed circuit. The refrigerant inside it circulates, it does not deplete, and it is not consumed the way fuel is. So if a unit is low on gas, there is a leak, and every top up that goes in without finding that leak is going to end up in the same place the last one did. Sometimes in weeks. This is the single most common thing homeowners in Dubai are quietly overcharged for, because a refill is easy to sell twice.
We test before we charge. The system is pressurised with dry nitrogen and held, which reveals whether it is holding pressure at all and, where it is not, lets us locate the loss at flare joints, brazed connections, the coil, or the line set. Once the leak is repaired and the joint is retested, the system is evacuated to remove moisture and non condensables, then charged by weight to the manufacturer's specification rather than by guesswork on the gauge. Superheat and subcooling are checked on completion and you get the figures in writing.

How the process works
Symptom and history
Tell us what changed and when, and whether it has been topped up before. That usually narrows it immediately.
Pressure test
The system is pressurised with dry nitrogen and held, which shows whether it holds and where it does not.
Leak located
We find the loss at the joint, coil or line set rather than opening things speculatively.
Repair and retest
The leak is repaired and that joint is retested under pressure before any refrigerant goes in.
Evacuate and charge
The circuit is evacuated to pull out moisture and air, then charged by weight to specification.
Verified and documented
Superheat and subcooling checked, figures written down, and the record kept for the next visit.

View serviceFrequently asked questions
How much does AC gas refill and leak detection cost in Dubai?
There is no fixed rate card. Price follows the size and condition of the property, so a senior member of the team surveys it first and you get a written, itemised quotation the same day. The figure on that quotation is the figure you pay.
Who does AC gas refill and leak detection near me in Dubai?
MELLS covers ninety communities across Dubai and works in Abu Dhabi and Sharjah for commercial premises. Message +971 58 656 3001 on WhatsApp with your community and we will confirm availability.
What is the best AC gas refill and leak detection company in Dubai?
Judge any company on three things: whether the team is directly employed or subcontracted, whether the quote is fixed in writing before work starts, and whether a supervisor walks the property with you at the end. MELLS does all three as standard.
How quickly can you start AC gas refill and leak detection?
Survey usually the same day you ask, quotation the same day, and work scheduled within forty eight hours in most cases. Urgent call outs are handled the same day where the team is free.
Is AC gas refill and leak detection safe for children and pets?
Yes. Products are selected for occupied family homes as the default, re entry times are told to you before we leave, and anything stronger is only ever used with your agreement.
How do I get a quote from MELLS?
Message us on WhatsApp on +971 58 656 3001 or call the same number. A senior member of the team surveys the property and you receive a written itemised quotation the same day.
Which areas of the UAE does MELLS cover?
Ninety communities across Dubai for residential work, and Dubai, Abu Dhabi and Sharjah for commercial premises.
Why does my AC need gas again so soon?
Because refrigerant is not consumed. It circulates in a sealed circuit, so a system that is low has a leak. If it was topped up without a leak test, the new gas leaves the same way the old gas did.
Can you just top it up quickly?
We can, but we will tell you plainly that it is temporary. Charging without testing means you are likely to be calling again within weeks, and paying for refrigerant twice.
Which refrigerants do you handle?
R410A, R32 and R134a, which covers almost all residential and light commercial systems in Dubai. We charge by weight to the manufacturer's figure, not by gauge pressure alone.
Is ice on the pipes a gas problem?
Often, yes. Low charge is a common cause, though a blocked filter or a failing fan can produce the same symptom. That is why the diagnosis comes before the quote.
Will this fix my high electricity bill?
If the system is undercharged it is running longer to reach the same temperature, so correcting the charge usually helps. We check filters, coils and airflow at the same time, because those affect the same number.
Ready to book ac gas refill & leak detection?
