  Aircon Systems had always confused me. But your straight to the point education on 'Understanding the System' was awesome! Not even more than 5 minutes to explain how it all runs. Thanks and cheers!

  After seeing several YouTube videos about Honda A/C diagnosis (and all seemed to point to a bad compressor), I borrowed an A/C gauge set from a friend. I was at 35psi low side / 150psi high side. Whew. Just low... One $12, 12-oz can of R134a got me into the 40s low side / 225 high side (idle, 95F outside). My 2007 Honda CR-V A/C hasn&apos;t worked this well in years! Freezin&apos; my butt off now!<br><br>Thanks for your tutorial! It helped me understand enough to fix it myself this time!

  Your explanation regarding &nbsp;the diagnosis via guage reading was very simple to understand, to the point and very exciting, though component wise faults, diagnosed via gauge readings would have been very helpful... Really look forward for a complete video component wise.... Best regards

  Great video. Mark on! Gauges are affordable for most people. Amazon has them from 40 bucks up. Guys like you can provide advice on which ones add the best bang for the buck. 👍👍👍👍👍💥✌️🙏🏻

  First off, love the channel, and your easy to understand repairs and methods. THANK YOU AND KEEP THEM COMING. My 2002 Merc Benz S430 (W220) A/C stopped working after I replaced the windshield wiper hose (with the heater wire/ cable inside). The unit small red light is on indicating the system works, but will not blow cold air. The clutch does engage, on then off, constantly. The typical reset feature/ trick doesn&apos;t work for whatever this error is currently. I checked the relays/ switched and replaced them as well. &nbsp;Assuming the system may have been low on refrigerant, I filled it with what it took in, which appeared to be almost two full &quot;tall&quot; cans of AC Pro. Reset the system and the air came on &quot;absolutely freezing cold&quot; for about two minutes then shut off again. After resetting and attempting to make it stay on, it wouldn&apos;t reset anymore after four attempts. I noticed a clear liquid had leaked from the bottom center of the car down the driveway to the rear of the car, no smell or color, but thicker than water. <br><br>The next day, with the engine running and the air refilled and reset once more, I heard a loud hissing and bursting flow of air or spray from under the hood, front drivers side for about 40 seconds then stopped. I believe it was a pressure relief vale of some sort !!! &nbsp;Scared the &amp;%$#@^&amp; &nbsp;%$#%^&amp;%#@ out of me to be exact. &nbsp;The clutch still engages, on then off, constantly. &nbsp;Whats wrong with the cars AC ????? What would you recommend I check or replace???? &nbsp;No AC for the past four months now...
