The short answer

Car AC gas filling in Arjan, Dubai, is booked through Arjan Battery on WhatsApp. It is a full recharge for a system that is empty or has been opened for a repair: the old refrigerant is recovered, the system is held under vacuum and leak-tested, then filled with the exact weight of R134a or R1234yf printed under the bonnet.

Gas filling is the last step of an AC repair, not a repair in itself. After a new compressor, condenser or hose, or after a leak has emptied the system, the pipework is full of air and moisture. Both have to come out before refrigerant goes in. Otherwise the new parts corrode from the inside and the cooling never reaches what it should.

What the job covers

  • Recovery of any remaining refrigerant by machine, not vented to the air
  • Deep vacuum to boil out air and moisture
  • Vacuum-hold leak test before any gas goes in
  • Fresh compressor oil of the correct type, with UV dye
  • Charge by weight to the under-bonnet label
  • Vent temperature and pressures checked afterwards

Signs you need it

  • The system was opened for a compressor, condenser, evaporator or hose
  • A leak was found and fixed, and the system is now empty
  • The compressor will not engage because the pressure is too low
  • The vents blow outside-temperature air with no cooling at all
  • Front-end accident repair replaced the condenser

Why a full fill is not a top-up

Air and moisture are the enemies of an AC system. Moisture reacts with refrigerant and oil to form acid, and it can freeze at the expansion valve and block it. Air raises the pressures and takes up room the refrigerant needs. Only a vacuum pump removes them. The receiver-drier, a canister of desiccant, should also be renewed when a system has stood open.

The second reason is weight. Each car takes a set amount, on most cars somewhere between about 400 and 900 grams, more with rear AC. A little too much or too little changes how well it cools. A pressure gauge cannot tell you how many grams are inside, so the only way to hit the figure is to start from empty and weigh it in.

The filling procedure

  1. 1

    Identify

    The label under the bonnet gives the refrigerant type, the charge weight in grams and the oil type.

  2. 2

    Recover

    The machine draws out what is left and weighs it, which shows how much had leaked.

  3. 3

    Vacuum

    A pump pulls the system into deep vacuum, typically for 20 to 30 minutes or longer, so moisture boils off and is carried out.

  4. 4

    Hold test

    The valves are closed and the gauge is watched. A needle that creeps up means a leak is still open, and filling stops here.

  5. 5

    Oil and dye

    A measured amount of the correct compressor oil goes in, with UV dye so any future leak can be traced.

  6. 6

    Charge and test

    The exact weight is charged, then vent temperature and both pressures are read with the engine running.

R134a and R1234yf

These are the two refrigerants in cars on UAE roads. They are not interchangeable.

Terms on the job sheet

Evacuation
Pulling the system into vacuum with a pump to remove air and moisture before filling.
Charge weight
The grams of refrigerant the system was designed for, printed on the under-bonnet label.
PAG oil
The compressor oil in most belt-driven systems. It comes in several viscosities, and the label says which.
POE oil
A non-conductive oil for the electric compressors on hybrids and EVs. PAG oil in those systems can damage the insulation.
Receiver-drier
A canister of desiccant that traps moisture. It is renewed when the system has been open to the air.
UV dye
A fluorescent tracer in the oil that glows at a leak point under an ultraviolet lamp.

Gas in a leaking system is gas on the road

If the vacuum will not hold, we stop and find the leak. Filling anyway cools the car for days or weeks. Then the refrigerant is in the air and the compressor is running short of oil again. Canned top-ups with stop-leak additives can also gum up valves and contaminate service machines.

How Car AC gas filling works at your door

No app, no account. One message is enough.

  1. 1

    Send your pin and your car

    WhatsApp your live location with the make, model and year, or call. In a basement, add the tower name and bay number.

  2. 2

    Get the price and arrival time

    We reply with the battery options that fit, the full price and how long the van will take. Nothing moves until you say yes.

  3. 3

    We test before we fit

    The technician checks the old battery and the alternator first. If a jump start or a clean terminal fixes it, that is what you get.

  4. 4

    Pay and drive

    Cash, card, Tabby or Tamara at the car. Your warranty of up to 24 months arrives on WhatsApp before the van leaves.

Typical time at the car: 15 to 25 minutes.

What drivers around Arjan say

  • HassanArjan, Nissan Patrol

    The Patrol would not start in the tower basement before work. The technician found the bay from the pin and level number I sent, tested the old battery and showed me the reading before changing it. He took the old one away with him.

    Battery replacement

  • JamesMotor City, Volkswagen Tiguan
    1 month ago
    My Tiguan has start-stop, so I asked if it needed an AGM battery. He checked the one fitted, confirmed it was AGM and fitted the same type, then coded it with a scan tool. Clear explanation of what he was doing at each step.

    Battery replacement

  • LaylaJVC, Kia Sportage
    3 weeks ago
    I thought the battery was finished because the car was slow to start. He tested the battery and the alternator and said the battery still had life in it and only needed a proper charge. He did not try to sell me a new one.

    Battery testing

  • MuhammadAl Barsha South, Toyota Corolla
    5 days ago
    I left the interior light on overnight. I sent my location on WhatsApp early in the morning and the car was running again before I had to leave for work. He told me to drive it for a while so the battery could recharge.

    My car had been parked for three weeks while I was travelling and it was completely flat. The technician jump-started it, then checked the charging voltage with the engine running to make sure the alternator was doing its job.

    Jump start

  • AaravDubai Science Park, Hyundai Tucson
    3 months ago
    The car would not start in the office car park at lunchtime. He replaced the battery while I went back to my desk and sent me a photo of the charging reading when he was done. The invoice has the warranty period written on it.

    Battery replacement

  • MaricelSports City, Nissan Sunny
    10 days ago
    My car did not start after my night shift. The technician jump-started it and tested the battery. He said it was weak and would probably need changing soon, but he left the decision to me.

Car AC gas filling: common questions

Not answered here? Ask on WhatsApp. A person replies, at any hour.

How do I know which AC gas my car uses?

Open the bonnet and look for the AC label, usually on the slam panel or the underside of the bonnet. It names the refrigerant, R134a or R1234yf, and the charge weight. If the label is missing, send the make, model and year and we check before the job is booked.

How long does car AC gas filling take?

On a sound system, recovery, vacuum, hold test and charge usually take about 45 minutes to an hour. Most of that is the vacuum, which should not be rushed. If the hold test shows a leak, the time depends on where the leak is and which part has to be replaced.

Can R134a be used in a car built for R1234yf?

It should not be. The service ports are different on purpose, the oil and the charge weight are specified for the original gas, and a mixed system cannot be recovered by a normal machine afterwards. We fill with the refrigerant named on the car's own label.

Is AC gas filling the same as a refill or top-up?

Not quite. Gas filling here means starting from empty: recover, vacuum, leak-test and weigh in the full charge, as you would after a repair. A refill is the lighter job for a system that has slowly lost some gas over the years. That one is on our AC gas refilling page.

Can AC gas filling be done at my building in Arjan?

It depends on the job. A full fill needs a recovery and charging machine, and a system that has just been repaired is normally filled where the repair was done. We tell you on WhatsApp if it can be done at your parking or goes to the workshop with pickup and drop-off.
