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...

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...

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...

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...

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...

Green color of residue suggests copper salts from corrosion of the copper tubes.

I believe that a separate recovery/recharge machine is required by regulation for each refrigerant type. Now for service gauges, I have R-12 gauge set, and actually purchased adapter fittings for that and used mine for both R-12 and for R134a. I later bought a set of R-134a gauges. And of course I u...

ok, i know this is going to sound crazy, and I'll probably get scolded for it, but I'll ask anyway... Anyway, this size can would be perfect for me to use to do the A/C on my truck (22oz), and it would avoid me having to deal with using two 12oz cans & having to purge the lines when swapping, k...

Yesterday, I was there with the truck and took a look at this with my UV light and yellow goggles. I checked the entire system, including compressor fittings, front compressor seal, condenser, drier, connections at the firewall, even the condensate drain hose, did not see ANY dye/leaks. Maybe the n...
