Stop Wasting Money on Frequent Gas Refills
If you find yourself going to a local garage to top up your AC gas every few months (or even weeks), you have a micro-leak in your system. Because the evaporator (cooling coil) sits hidden deep inside the car's cabin, it is the most common and most frequently misdiagnosed source of refrigerant leaks.
At Daga Autolek, we don't believe in temporary top-ups. We find the leak and fix it permanently.
Signs Your Cooling Coil is Leaking:
- Fading Cooling: The AC blows ice cold after a gas refill, but slowly becomes warm air after a few days or weeks.
- Hissing Sounds: You hear a faint "hissing" from the AC vents when you turn the car off.
- Oily AC Drain: Traces of refrigerant oil dripping from the AC water drain pipe under the car.
- Chemical Smell: A faint, sweet chemical smell inside the cabin when the AC is turned on.
The "Dashboard Rattle" Fear (Solved)
We know exactly what car enthusiasts fear most about replacing a cooling coil: opening the dashboard. Many local mechanics tear the dashboard apart piece by piece, breaking delicate plastic clips, misaligning steering columns, and leaving you with permanent rattling noises.
The Daga Autolek "Single Unit" Method
- Zero Rattles: Our technicians are trained to remove the dashboard assembly as a single, intact unit by unbolting the main metal cross-beam.
- Factory Fitment: All fragile plastics, AC vents, and air ducts remain completely undisturbed. When re-installed, your dashboard fits exactly as it did from the factory.
Nitrogen Testing & OEM Replacements
Most AC shops test for leaks by pumping highly pressurized, moisture-laden air into your system (often upwards of 350 psig), which can actually damage delicate pressure switches. We use dry Nitrogen gas at safe pressures (~200 psig) to accurately detect micro-leaks without introducing damaging moisture into the receiver drier.
Once a leak in the evaporator is confirmed, we replace it with a 100% original unit from Subros, Behr, Denso, or Delphi. We then pull the system into a deep vacuum to remove all impurities before executing a precise, machine-weighed refrigerant recharge.
Frequently Asked Questions
Because we remove the dashboard as a complete assembly, our turnaround time is faster. For most major Indian and imported cars, we complete the job and return your car on the very same day, if brought it during opening hours. It can sometimes take 2 days for more complex issues.
While older, thick copper coils could sometimes be welded, modern cars use highly efficient, thin aluminum evaporators. Welding these is extremely unreliable and the leak almost always returns. For peace of mind and long-term savings, a full replacement is mandatory.
Yes! Since the HVAC unit is removed from the car, we thoroughly clean the blower motor assembly and replace the cabin air filter, ensuring the air blowing into your face is completely pure and dust-free.
