Pressure and Temperature Checks
Readings from the system are taken first to confirm whether the refrigerant level is really the cause of the poor cooling.
AC Gas Refilling in Dubai
Refrigerant checked, leaks found and gas topped up to the unit's specification
In Brief
AC gas refilling is topping up the refrigerant in an air conditioner whose gas level has dropped, after checking pressures and looking for the leak that caused the loss. The sealed system should not normally lose gas, so a unit that needs regular refills usually has a leak that should be found.
An air conditioner moves heat using refrigerant that circulates in a sealed circuit. In normal running that gas is not used up, which is why a unit that has lost its cooling because of low gas almost always has a leak somewhere: a joint, a pipe connection, a flare nut or the coil. Refilling alone can bring the cooling back for a while, but if the leak is not found the gas will drain away again and the compressor works harder in the meantime.
We start with pressure and temperature checks to confirm that low gas really is the problem, because weak cooling can just as easily come from dirty filters, a failing capacitor or a blocked coil. If gas is low we look for the leak, repair it where it is accessible, and top the system up with the refrigerant type the unit is designed for. Gas work sits alongside our wider AC maintenance and repair service, and a dirty coil can mimic a gas problem, so we often recommend an AC cleaning first.
When You Need This
Signs You May Need AC Gas Refilling
- The AC runs but blows only slightly cool or warm air
- Ice forms on the indoor coil or on the copper pipes
- The unit takes much longer than before to cool the room
- You can hear hissing near the indoor or outdoor unit, or see oily marks at pipe joints
- Your electricity bill has risen without a change in how you use the AC
What We Do
What AC Gas Refilling Covers
Leak Checking
We inspect joints, connections and the coils for signs of a leak, so the gas loss is dealt with and not just masked.
Leak Repair Where Accessible
Loose flare connections and accessible joints are tightened or re-made, and we tell you if the leak is in a part that needs replacing.
Refrigerant Top-Up to Specification
The system is charged with the refrigerant type shown on the unit, to the level it is designed for, not simply until it feels cold.
Coil and Filter Check
Dirty filters and coils are checked at the same time, since they cause the same symptoms and put extra load on the compressor.
Cooling Test Before We Leave
We measure cooling after the work and listen for abnormal noise before we consider the job complete.
Our Process
How It Works
- 1
Describe the Weak Cooling
Tell us the unit type and age, how long it has been weak and whether you have noticed ice or hissing. A photo of the unit label helps us confirm the refrigerant type.
- 2
Measure Before Refilling
A technician takes pressure and temperature readings to confirm low gas, and rules out airflow and electrical causes first.
- 3
Find and Fix the Leak
We look for the source of the gas loss and repair what can be repaired, then explain what we found and what it will cost before charging.
- 4
Charge and Test
Gas is added to the specification for the unit, and we check cooling, pressures and noise before leaving.
Good to Know
What Affects Time and Cost
Every property is different, so we confirm the price before any work starts. These are the things that most often change the time and cost.
- The refrigerant type the unit uses and how much is needed
- Whether a leak is found and whether it can be repaired or needs a part replaced
- The type and size of the unit, such as a small split or a large ducted system
- How easy the pipework and outdoor unit are to reach
- Whether dirty coils or filters also need cleaning to restore cooling
FAQ
AC Gas Refilling Questions
A sealed AC system should not need regular refills. If a unit keeps losing cooling because of low gas, there is a leak, and we recommend finding and repairing it, not simply topping up again.
Not necessarily. Dirty filters, a blocked coil, a failing capacitor or a faulty fan can cause the same symptom. We take readings before adding any gas, so you only pay for refrigerant if it is actually needed.
Yes. We use the refrigerant type the unit is designed for, shown on its label. Different refrigerants are not interchangeable, so we check before charging.
Where the leak is at an accessible joint or connection, yes. If it is inside a coil or a hard-to-reach pipe, we explain the options, including whether replacement makes more sense. Our AC maintenance and repair page covers wider repairs.
It depends on the refrigerant type, how much is needed and whether a leak has to be repaired. We confirm the price before any gas is added.
