Professional AC Regassing and Servicing
Over time, it is normal for an air conditioning system to lose a small percentage of its refrigerant gas through microscopic pores in the rubber hoses and seals. When the gas level drops too low, the system can no longer effectively cool the air.
Our AC regas service involves recovering any remaining old gas, placing the system under a deep vacuum to remove moisture and impurities, and then recharging it with the exact, manufacturer-specified weight of new refrigerant gas and compressor oil.
We inject a UV dye during the regas process. This is a crucial step, as it allows us to easily pinpoint the exact location of any future microscopic leaks using a specialized UV light.
Advanced Leak Detection and Repair
If your AC stops working shortly after a regas, you have a leak. Simply repeatedly gassing a leaking system is illegal, bad for the environment, and a waste of your money.
We utilize electronic sniffer tools, nitrogen pressure testing, and UV dye inspection to locate even the most difficult-to-find leaks. Common failure points include cracked condenser cores (often damaged by stones through the grille), leaking O-rings, and porous rubber hoses.
Once the leak is identified, we provide a quote to replace the faulty component, ensuring the system is completely sealed before we regas it.
Compressor and Electrical Faults
The AC compressor is the heart of the system, pumping the refrigerant gas through the lines. If the compressor fails or seizes, it can send metal debris throughout the entire system, requiring a massive and expensive cleanup and replacement of multiple components.
Sometimes, the AC issue is not related to gas at all, but is an electrical fault. As a qualified auto electrician, Damien can quickly diagnose faulty pressure switches, blown relays, broken wiring, or a malfunctioning climate control module inside the cabin.
We ensure that the electrical circuits controlling your air conditioning are functioning perfectly, engaging the compressor clutch exactly when required.
