15 June 2015 Review: YourMechanic.com Recently, I had the opportunity to check out a service that I had, for quite awhile, wondered about and would it fit with the ever-changing consumer worldview. Okay, at least, here in the United States. YourMechanic.com offers to come to you and service your vehicle's needs. While you continue your work day; they continue theirs. When all is done, that's exactly that. They're done with their day, you're done with your day and the day-off your car unexpectedly took is also done. Now, you're back on the road or at least able to head out if there's someplace you have to be. Although this may not be a new service; it is for me. I'm glad I found it, used it and now I can recommend it. The mechanic I met, Peter, came with 35 years of experience, licensed, prepared and engaged. I haven't found that at decades old, established companies anywhere, ever. Perhaps, that old model, along with its particular brand of hassles and drawbacks is becoming obsolete. One thing for sure, it won't be missed by me. In as much as the auto/mechanic industry is not my primary area of expertise, allow the following illustration which draws on my personal background to drive home the point: If YourMechanic.com were to announce an Initial Public Offering (IPO) tomorrow, you bet you'd find me among those first in line positioned to grab up as many shares as possible for a long term "hold." Regards, David Duke, Phoenix, Arizona *Note: Please strike this note from the official review as it is intended for inter-office use only. Please feel free to correct any glaring typos I may have overlooked. I am submitting this with a deadline in mind.

All about 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 Freon 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.
