How do you use an air conditioner charging manifold? How do I connect gauges to my AC condenser unit? How to take hoses off of air conditioner. How does an AC gauge manifold work?
Those are a few of the questions that I will answer in this detailed video explaining all of the basics that you need to know about standard ac pressure gauges.
This is one of the essential things that you need to know in order to understand what is going on with your air conditioner, heat pump, or mini split unit.
I also show how a dirty air filter can affect the low side pressure of a system & why it is so important to have a new filter installed on a regular basis.

About time I find someone who can explain how to use gauges so understand what they are talking about. Thanks!!!

[@maxclark11]

Done refrigeration of 47 years. Excellent presentation. Suggestion if you find yourself in this situation. Hold the hose firmly against the valve and totally loosen the hose fitting. Then quickly pull the hose off the fitting. You will still get the blow off but you will have better control of where it sprays. If you have low loss fittings, I like to remove the high side first, then open both valves and return the refrigerant that is held in your gauge manifold back into the a/c system, then remove the low side hose.

Great video Ben, Being 78 YO I probably will not be going out and buying a set of gauges. I will be selling my home and moving in about a year so now I am in the process of giving most of my larger tools away to family. I have decided to rent and let someone else do all the work and enjoy my final few years without having to fix everything around the house. All the same, I really enjoy your videos. One is never to old to stop learning new things.

Hi Ben watch your video is Pretty good and interesting

[@duaneroepke8840]

Watch this several times and take notes. If you have someone come service your unit you could look at the gauges and at least know WHAT your looking at and also have an idea if you are being scammed. By knowing what to look for even if you don't do the work is power and protection.

[@pucketts57]

I took classes for HVAC for parts of 4 years from a rip off trade school in Leesburg Va . -- Monroe Vo Tech They kept dragging the class work out for more money But I ve learned more in the 26 & 1/2 minute video than I learned in all the time I spent in the classes Not one person in all the classes made it into the HVAC field & I trusted them till I couldnt any longer Thanks you for showing me the right way to do this

[@NikoBellaKhouf]

That's awful. 4 years?! I took an accelerated class, full time for 6 months. It cost $12k. It was a rip-off also, but at the very least, they prepared us to work in the residential field. Can you and the others sue the school?

Benjamin this is a great video. I really enjoyed how you simply explained every thing .

[@russoft]

Thank you for explaining the bleeding/flushing of the lines for charging refrigerant! Some other videos explain how to flush the yellow line, but it never made sense to me that they ignored the air inside the low/blue and high/red lines. The fact that the refrigerant pressure is above ambient and thus the air won't enter the refrigerant loop makes sense, but I come from a cryogenics background where air and helium (refrigerant) mix quickly and readily and such a practice will likely kill the system in short order.

[@johnakagi1088]

I watched this video again for a tuneup on my AC gauge knowledge. Still THE best video on AC gauges I have ever seen. Just an update on the mini split 36k in my 30x40 R-4 insulated metal building. I did add rubber seals and brush seals to my roll up doors to help reduce conditioned air from escaping. The mini split has exceeded my expectations on controlling the temperature in my shop. It cools and heats where I am comfortable in all weather temperatures here in Texas. There is maintenance of cleaning the inside filter especially when wood working and I do clean the dust from the fins one the outside. I turn off the unit when mowing. When not heating or cooling I keep it on dry setting. My table saw jointer and planner do not rust because the system pulls the moisture out of the shop. Lots of humidity in Texas. Be blessed!!!

Close the high side valve on the system then open both valves on the gauges (while the yellow line is sealed). This will drop the pressure in all 3 hoses. Then close all valves including the low line of the system. Now you can take remove the gauges with less spray.

Benjamin I like how you explain in detail on how to use gauges. I needed to know how to connect the hoses and if you open the valves on the gauges while just solely checking refrigerant. "make sure valves are closed are will leak out" & how you explain to wear gloves etc. Great content! Awesome video! very well explained! I subscribed and watch the entire video because you explained every thin in detail!.

Just watched this as a refresher course for my old brain that's pushing 70 and 25 years out of the business. Great "old school" presentation without clouding the issues by adding spurious details. Yes, the other things are important, but more to do fine tuning and troubleshooting. The basics will get you going 98% of the time. Now I just need to dust off my Robinair gauges from 1973. Yes, still solid after almost 50 years, although the hoses are getting a bit stiff. Edit: I did the job and found a minor leak at the service valves. (not fully back-seated) Topped up the system and gained several degrees of cooling, measuring at the low side line. New air filter and got 17 - 18 degrees TD across the inside coil. Can't ask for much better!
