Awesome experience!! Chris was great!! I was extremely satisfied with his service. I would recommend him to family and friends. Besides delivering a new battery and installing it, He checked all the fluid levels, checked the tire pressure and made sure all the the malfunction lights went away. He was very professional, knowledgable and friendly.The final bill was less than I was quoted, because he gave me a $20.00 discount.I asked for his card so that I could request him if I need YourMechanic services again. Love this company!!!

Normally I do not confess to auto techs that I spent 40 years as a GM Service Manager and Service Advisor. BUT, Brikk was so pleasant and likable, our conversation was that of cars. He not only fixed my problem, but was sure to check other items on my car that I had not complained about. As I always tell everyone, there is but one thing that surpasses great customer service, and that is MORE of it...Thank you Brikk for a job well done, and if I ever need your service again, consider your phone ringing...Thanks

All about Car AC Compressor Replacement

An AC system has many components: compressor, condenser, receiver dryer, evaporator, and hoses. The compressor, the “heart” of the car’s air conditioning system works like a pump taking refrigerant, (R-12 in older cars, R-134a in 1995 and newer cars) and pressurizing it, passing it along to the evaporator. The AC compressor has several moving parts (including pistons and valves). These internal parts can fail, causing the AC compressor to stop working. It is common for the internal parts of the compressor to come apart and disperse metallic debris throughout the system. Consequently, it is a requirement to replace the orifice tube and the receiver dryer when replacing the compressor since some of the debris may have ended up there. For an AC compressor to work, it needs a clutch, bearing, and an electrical connector. The clutch is driven by a drive/serpentine belt, which engages the compressor when you switch on the AC. The clutch can burn or the bearing can fail. If the bearing or clutch have failed, it is recommended that the compressor be replaced. Sometimes replacing the entire compressor with a remanufactured one can be cheaper than replacing an individual clutch or bearings. It is also common for the seals in the AC compressor to go bad. The compressor may start leaking refrigerant and/or the AC oil. If the seals no longer hold, you will need a new compressor, as the seals cannot be replaced. A compressor may also fail if there is sludge or debris in the air conditioning system. If there is sludge or debris, the hoses, evaporator, and condenser should be flushed to get rid of the contaminants. When it is not possible to flush the parts, you may need to replace those parts.
