We’re Certified Mechanics

An AC system is very complex with switches, sensors, relays and control modules, and you’ll want a trained technician to work on your system, such as us. Our certified technicians use only the highest quality OEM parts from the manufacturer. We’ll check your coolant level, check for a possibly defective control valve or thermostat issue, and make sure the heater core isn’t plugged. And the good news is, you’ll get quality work without the dealership pricing!

Why Is My Audi AC Not Blowing Cold Air?

  • Noise when AC is turned on

Happy Customer Reviews

“Brian was very responsive, competent and fair in his approach to fixing our 2010 Audi A4 (110K miles). He gave me a fair price for a lot of work to fix an engine leak while taking into account my desire to not pour more money into this car than it may be worth. He also performed the same 30K service on my wife’s Porsche Macan that would have cost me twice as much at a dealer. Highly recommend Four Rings for reliable and honest work!”

“Brian was quick to respond to my online question and I was able to get in the next day. Upon meeting him, I was glad to know that this guy knows Audis. After inspecting my car, he called with some affordable options. Feels good to have a local Audi mechanic that is not the dealership. I have been taken for way too much from the local dealership and will continue to use Four Rings in the future.”

– Anthony R., Moorpark, CA / 5 Stars Yelp

“Took my 2015 VW in for a water pump and thermostat housing replacement and Brian got all the parts needed and installed them in a very timely manner. Communication was good and he answered my questions and concerns throughout the process. I would take my car back here for future services and will recommend him to friends.”
