HVAC Tips to Avoid Vacuum Problems! Top 15!

In This Video, I go over The Top 15 HVAC Tips for Solving Vacuum Problems. After Pressure Testing Refrigerant Lines, we need to Dehydrate the System below 500 microns in order to prepare it for the Addition of Refrigerant. I go over Tips to make the Jobless Frustrating, Less Time Consuming, and Increase Productivity! You can also add a dab of vacuum pump oil to the rubber grommets of the vacuum hoses but make sure that none goes in the vacuum gauge. Supervision is needed by a licensed HVAC Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.

Dude your way better than any instructor I’ve had in technical school. Kudos

[acservicetechchannel]

Also make sure to have a dab of refrigerant oil on the rubber grommets of your vacuum hoses. Some people use Nylog for this. I just use refrigerant oil. Make sure to not put a dab of oil on the micron gauge connections as you don't want any oil close to the micron gauge sensor, thanks!

[Neversink_Pirate_Radio]

Another thing to consider is not allowing the micron gauge to be leaning down allowing oil to be pulled into it getting it dirty. Dood your videos are on point your have the whole game on lock thank you thank you knowledge is power and your sharing that

Hey brotha, I'm a new man. rep who's new to the industry, and this is my first time viewing your work. I appreciate your attention to detail and correct instruction.

[jamesrockford]

Watched again, your a class act!!
World class instruction.

I’ve been going crazy on the vacuum lately, it’s a fun trial and error finding new ways to get it down quicker

[HVACinSC]

Great tips! Enjoyed the video. The Bluevac micron gauges are designed to handle positive pressure up to 500 psi specifically so pressure can be put back into the system prior to removing the micron gauge. Im not sure of other manufactures. Keep up the good content!

Thank you, I've had 3 technicians come out recently and not be able to figure out the problem. Your videos helped me to help them fix the problem. I'm not placing blame on anyone but if they had your style of teaching in the courses, I believe the field would see much better technicians.

Hello to all,
The picture is my wife.
Just installed my first split 3 ton system. New air handler and outside unit precharged with 410A.
Brazed in a new line set with filter dryer at air handler and sight glass on liquid side outside, using Nitrogen at 3CFM.
Charge system to 400 psi with Nitrogen for 10 minutes and bubble checked for leaks. No loss, no problems so far!
Time for vacuum test! I have a 6 CFM Yellow Jacket pump with new oil, 3 Appion Valve Core removal tools, new CPS Micron gauge, and new Yellow Jacket 4 hose gauge set.
Valve cores have been removed since the brazing process. Set up the 3 Appion tools with CPS gauge as seen in video. Using only one 3/8 vacuum hose from pump to 4 hose gauge set, took about 30 minutes to pull down to 400 microns. Closed the 2 Appion valves with pump still running and starting losing vacuum. Checked/tightened all connections and opened valves again.
Pulled back down to 400, then with pump still running, closed valve to gauge only. Losing vacuum. Opened the valve, back to 400. Then it is starting to RAIN! Closed the valves and turned the pump
off and got everything under cover. Checked/tightened all connections, still losing vacuum and still raining. So with the test of closing just the valve to the gauge only and still losing vacuum, doing a 10 Minute test was not doable. I figured give it one more pump down to 400 microns, put the valve cores in, remove the CPS gauge and release the refrigerant to the system, put the tools in the truck and go home. When I got home, I saw there was vacuum pump oil in my gauge set lines. I checked the oil level in the pump and it was at the bottom of the sight glass.
OK, now I have vacuum pump oil mixed with refrigerant in my new system! What would you do?

Thanks,
Ricky

Also.. always have your micron gauge upright. Keeps oil droplets out while vacuuming.

Another informative & well-explained video. Keeping everything together in a vacuum kit makes a lot of sense. I mark the hoses that I have pulled the cores out of with zip ties...it let's you know immediately & you can always cut them off if you ever need to reinstall the cores. I think lusing your oil blowout method may also help remove moisture. Did you mention cycling the valves on the core removal tools during the vacuum process in this video? Again, thank you for putting this information together & sharing it.

Very logical line of videos. Bought your troubleshooting book and appreciating your experience. Starting my own business soon and found your channel relevant in that pursuit, and in my daily work in the meantime.

[MasonNesson]

Another very informative and useful video by AC Service Tech !

[MC-mqmh]

As always great video. I appreciate the time and effort you put into your videos.

[leoashrae]

When I have problems with leaking service valves I've used a few drops of NyLog to seal it long enough to get my service finished. I run the valve all the way down (just as you have shown in the video), wipe a long-stick Q-tip soaked with the appropriate NyLog, in the bore, and then re-back-seat the valve back out. This usually does the trick

I whole heartily appreciate your knowledge, and your help.

Very good detailed instructional video.

Love the info and the 3 valve core puller setup.
