  1. I remember charging an A/C system years ago for a nasty rude man. During the vacuum stage I tapped on the lines to release any air bubbles. Got the temperature inside the car to freezing. Of course he then complained it was too cold. Told him he could adjust the temperature. There is no pleasing smell people.

  2. Love the dont forget me tag on the temp probe! Your a pretty smart feller lol or fart smeller! Thank you for the hands on education and for free my goodness we are blessed these days!

  3. You know that was not an ordinary Lizard. That was an under cover Geico Insurance Scam Agent making sure that only real insurance work gets billed to them and not routine maintenance stuff.

  4. Wow, juat paid $160 to have that done and no leaks were found on my Chevy Trailblazer. He emptied and refilled my system and it still stopped working on the way home. Now I've finally noticed when it stops working. When the screen says it's 90 degrees or more outside the A/C stops working and starts blowing warm air, when the screen temperature reads in the 80s or lower the air conditioning blows cold. I don't know what the heck could be causing that. GM only issue I'd bet.

  5. How does this happen? Schrader valves don't leak unless they get very old. Were they penny-pinching and installed crappy ones? Or are there contributing factors? Are they identical to the ones used on tyres? Or do they have to have a different o-ring material like vyton or something?

  6. Some of those, if not all, low side switches can be replaced with system under charge. I had to do that on my truck. Turns out there is a build in valve that allows changing out without system evac. make it nice for when that switch failed. One reason the switch fails often is due to all the clutch current, several amps, goes though the switch and it normally cycling when not doing full AC output. Some system run a relay to prevent that.

  7. I specialize in auto ac. I replace every charge port and Schrader valve in every car I work on. If I don't it's guaranteed that I will have to suck it out and redo it. I also am the only guy in my area that can make a hose or line.

  8. Super Lube 56204 O-Ring Silicone Lubricant, Clear New 202 Please use this on o rings . Same principle as putting oil on oil filter. Thank you
