Re: Drain oil out of new compressor?
My replacement compressor comes loaded with oil, some say drain and refill but Im not sure why? I'm not an AC professional. 1. The oil in the replacement compressor might be of the incorrect type. In the early 2000s I once purchased a replacement compressor (from this board's sponsor) for my 1988 M...

Re: Reusing R134A
I'm not an AC professional.
Using my home-made recovery system (which uses dry ice and alcohol), I have recovered and re-used both R-12 and R134a.

Re: What is best way to seal up/get ready a system for later vacuum and charge?
A modern AC recovery/fill machine can do this at 80F.
If you leave the system empty or under vacuum, air and moisture can enter.
If it ever got colder than 80F here in Phoenix, I'd still fill my vehicles.

Re: Receiver Filter Drier selection questions
If you have a minor leak, that's a different problem. As I understand things: The drier can retain tiny amounts of moisture, but it's main function is to ensure that liquid refrigerant goes to the expansion valve, why it feeds from the bottom and gets installed pretty much vertically. I'd say that a...

Re: Does air get in system when using AC manifold gauges?
My question was about just hooking up gauges in general, on a working system (not on an empty one or one that needs to be charged), in order to measure pressures. Say, for example, I want to double check pressures on a really hot day a month from now... I'm not an AC professional, but I say "N...

Re: Compressor life
No, no, no - that's not what I'm asking ! You both replied on how to keep a compressor "ready" during the winter. I'm asking about summer driving, whether switching compressor off every few minutes or leaving compressor on full-time and blending in some heated air is better for long-term c...

Compressor life
I have a question about AC compressor life in my 3 compact trucks; when the AC gets too cold, I've been switching off the AC using the push-in switch on the dash, and then pushing that back in turn the AC back on when it warms up. So my question is - for compressor life ONLY, not for gas mileage, et...

Re: New Ac system acting up - need advice
I'm not a professional, but I also believe you are low on refrigerant: When I Rev up the engine, the low side drops to 20psi and the high side goes up to 150 psi and the ac clutch cycles off. I'm in Arizona, so not as cool as Florida. At about 2000 rpm, I would expect low side pressure to be about 3...
