AC Blowing Warm Air? Here's What's Actually Wrong
Nine times out of ten, when a customer calls us saying their AC "isn't cooling anymore," the problem isn't the compressor or the thermostat — it's a refrigerant leak. The gas has slowly escaped through a cracked joint or corroded pipe, and the unit is running on fumes.
A lot of handymen will just top up the gas and leave. It feels like a fix, but it isn't — you'll be calling someone again in a few weeks. We trace the leak first, seal it properly, then recharge the system so it actually stays cold.


Why Your AC Keeps Running Out Of Gas
Here's the part most people don't know: an AC system is sealed shut. The refrigerant inside is supposed to just keep circulating between liquid and gas, absorbing heat from your room and dumping it outside, forever, without ever needing a top-up. So the moment your gas level drops, something physical has gone wrong — a pinhole in a copper line, a loose flare fitting, a corroded joint.
The trouble is, low gas doesn't announce itself right away. What you notice first is the compressor working harder than usual, running longer cycles, and your DEWA bill creeping up month after month. By the time the air actually feels warm, the compressor has already been under extra strain for a while — and that's the expensive part to replace.
We check pressure readings against manufacturer specs for your exact unit, run a proper leak test instead of guessing, weld or replace the failed section, and only then recharge with the right refrigerant type and quantity. It takes a bit longer than a quick top-up, but it means you're not paying us again next month.
8 Signs Your AC Is Leaking Gas
Most of these show up weeks before the AC actually stops cooling. Catching one early usually means a same-day fix instead of a full breakdown.
Room-Temp Air From The Vents
Unit is on, fan's running, but the air coming out barely feels different from the room. That's the clearest sign gas is low.
Frost Or Ice On The Coil
Low pressure drops the coil temperature below freezing, so moisture in the air turns into a layer of ice on it.
Hissing Near The Unit
A faint hiss or bubbling sound around the indoor or outdoor unit usually means gas is actively escaping right there.
DEWA Bill Climbing
A compressor starved of gas runs almost non-stop trying to hit your set temperature, and that shows up on the bill fast.
Room Takes Forever To Cool
If it's taking well over an hour for a bedroom to feel comfortable, the heat exchange is no longer working properly.
Water Pooling By The Unit
That ice buildup on the coil eventually melts, and it drips out as puddles you weren't expecting near the AC.
Weak Airflow From Vents
A frosted coil physically blocks air from passing through it, so what reaches the vent feels thin, even at full fan speed.
An Odd Chemical Smell
A larger leak sometimes gives off a faint sweet or chemical odour near the unit — worth calling someone the same day.
A Top-Up Isn't A Repair — It's A Pause Button
We get this question a lot: "can't you just add gas and I'll call again if it happens?" Technically yes, but think of it like pumping air into a tyre that's already punctured. It'll hold for a bit, then you're back where you started, except now you've paid twice.
Refrigerant is also a pressurised gas, and handling it without the right recovery equipment isn't something to take lightly — it's both a safety issue and, if it's just vented into the air, bad for the ozone layer. We recover what's left properly, fix the actual point of failure, then recharge with the correct gas for your system.
You Stop Paying Twice
Fix the actual hole once and the gas stays put — no repeat call-out in a few weeks.
Handled Safely
Pressurised refrigerant needs recovery equipment and proper training, not guesswork.
No Vented Gas
Old refrigerant is recovered and disposed of properly instead of released into the air.
Compressor Stays Protected
Running low on gas is the fastest way to burn out a compressor — fixing the leak protects it.
Step By Step What We Actually Do
No shortcuts. Each visit follows the same sequence whether it's a small studio split unit or a full villa system.
Find The Leak
Pressure test and electronic leak detector to pinpoint exactly where gas is escaping, not a guess.
Recover Old Gas
Any remaining refrigerant is safely pulled out with recovery equipment, not released into the air.
Weld Or Replace
The cracked joint or corroded section of copper pipe gets welded shut or swapped out entirely.
Pull A Vacuum
Removes trapped moisture and air from the lines so the repair actually holds under pressure.
Recharge The Gas
Exact weight and type of refrigerant per the compressor's spec plate, weighed in, not eyeballed.
Run And Verify
System runs while we track supply air temperature and pressures to confirm it's cooling properly.
What It Costs
Rough starting prices below. Your quote depends on unit size, gas type, and where the leak actually is — we confirm the exact number before touching anything.
You get the final price confirmed before any repair or refill work starts.
Leak Detection
Pressure testing to find where the gas is actually escaping
Copper Pipe Welding
Patching or replacing the cracked or leaking line
Gas Top-Up
Only if there's no major leak, just a slightly low system
Full Recharge
Vacuum and complete refill after a major leak repair
Same-Day Emergency Repair
Priority visit for a sudden breakdown in peak heat
Prices shift with unit size and gas type. A large ducted system takes more gas and time than a small split unit. Fix On Click is an independent service provider — call us directly for an exact quote based on your AC brand and model.
What's Actually Causing
The Leak In Your System?
A properly working AC never technically "needs" gas topped up. It's a sealed loop — the refrigerant just cycles between liquid and gas state without ever getting consumed. So if a technician tells you it's simply "low on gas," the real question is where that gas went, because it didn't disappear on its own.
In Dubai specifically, we see corrosion as the number one cause. High humidity combined with salt in the coastal air eats through thin copper joints over a few years, leaving pinhole leaks you'd never spot with the naked eye. Compressor vibration is the second big one — years of constant running shakes flare fittings loose bit by bit until they finally give way.
The third culprit is installation quality. If a flare joint wasn't torqued correctly on day one, or the wrong size copper was used for the run, the system pressure eventually forces its way through that weak spot — sometimes within the first year. This is why we check the whole line, not just wherever the compressor happens to be.

Questions People Actually Ask About AC Gas Leaks
Real questions from real calls, answered straight.
Is it normal for AC gas to run low every year?
No, and that's worth repeating — it's not normal. A sealed AC system doesn't consume refrigerant the way a car burns fuel. If your technician tops it up yearly, there's a leak somewhere that keeps getting ignored.
Can't someone just add gas without fixing anything?
They can, and plenty of people do. But depending on how bad the hole is, that gas can leak right back out in weeks or even days. You end up paying for the same job twice instead of once.
Why does my AC have ice building up on it?
When gas is low, the pressure inside the coil drops too, and that makes it colder than it should be. Any moisture in the air around it freezes solid, so you end up with an ice-covered coil instead of a cold room.
How long does a proper leak repair actually take?
Usually 2 to 4 hours from detection to a fully tested recharge, depending on how accessible the leak is. If the pipe runs through a wall or ceiling void, it can take a bit longer.
Is a refrigerant leak actually dangerous to be around?
In a well-ventilated room, a small leak isn't going to hurt you immediately, but it's still worth fixing quickly. If you notice a chemical smell or feel dizzy near the unit, switch it off and get it checked the same day.
Will fixing the leak actually lower my DEWA bill?
Yes, usually noticeably. A properly charged AC cools the room and cycles off. One that's low on gas runs almost continuously trying to hit the same temperature, and that shows up directly in your electricity usage.

Stop The Leak Before It Costs You More
Every week that gas keeps leaking, your compressor works a little harder and your DEWA bill climbs a little higher. We'd rather find the actual problem now than sell you another temporary top-up next month.
