    I am willing to bet that the reason for the compressor failure has nothing to do with the retrofit.

    Didn't the same thing happen to "Dog the Bounty Hunter"? He said some inapproprate remarks about African Americans, and yet his show is still on the air. If they do not bring Phil back, then A&E is a...

    I guess the point I was making was about "Karma" It always has a way of catching up with you. I think this applies to both OJ and George Zimmerman.

    It will be intersting to see if how these systems stand up to the test of time. We have alot of R22 RTUs and I have leaning toward R407c since it has the least amount of capacity lost. I like this...

    The person who soldered that condenser obviously didn't prep the lines correctly. Maybe he used the wrong flux and that's why the leaks formed. I have both brazed with 15% rods and used Staybrite 8....

    Its cheaper from a breakdown point of view that you are not straining the motor as much by cycling it as oppsoed to running it continiously. Electrical usage will about the same in either case.
