Just finished raising my disable kids and getting ready to go back into the field of AC HVAC . Thanks because I can't afford to go into debt so I watch your ads or just let them play.
My first dive into digital manifold was a pair of Testo 550s when they first came out years ago. One dedicated to R-22 and the other to R410a (residential & light commercial). I've taken good care of them, and they've served me very well. They make short work of most system diagnostics, but there remains a place for analog now and then, such as unusual fluttering TXV behavior. My favorite feature of the digital set is the ability to deal with temperature compensation when running system leak tests/tightness, and sorting saturation temps of virtually any modern refrigerant. I haven't yet jumped to completely into wireless yet, but the writing is on the wall, and I say good riddance to wires and hoses!
Craig, Great video. Our equipment is normally 98% heat pumps. Should we be working with heat pump manifolds where both gauges max out at 800 p.s.i.? Our question is since the low-pressure gauge is in increments to 800 p.s.i. does this make getting accurate pressure on the low-pressure side difficult?
Great video. What is Superheat and Target Superheat ? Do we check superheat in Heat winter ? For AC Do we need to check superheat in summer ? Thank you.
We check total superheat at the outdoor unit vapor port and vapor line for systems that have a fixed orifice running in air conditioning mode. The temp must be above 70 degrees inside and 70 degrees outside. to measure it accurately. Target superheat is determined using the indoor wb temp and the outdoor db temp. These are input onto a target superheat chart or app in order to determine the target superheat for the system. We must make sure that the total superheat matches the target superheat for an accurate refrigerant charge, thanks!
Hi Craig, Maintenance Supervisor here just moved to GA so I have to work on AC now. My in-law gave me a testo 549 to start with till I figure out what gauges to buy. I'm thinking of buying the testo smart probes ( range is not really an issue for me ). The question I have tho is... I have a lot of temp workers on my property who don't even bother checking SH/SC in order to properly charge the system. They basically have a set of analog gauges and that's about it and they pump low side up to about 130-140 and leave it. All of them claim they have more than 10 years experience in the field. How is that even possible? I always check pressures and temps to get the full picture
Most entry level Tech’s can’t afford the field piece digital Gauges and they tend to dumb down the techs. Just my opinion. They are expensive and you better be careful with them banging around your service truck. Also when parts of it goes bad such as thermistor wires to clamp on sensors they are very expensive to replace. I love new technology and wireless Bluetooth but you generally have to be within 30’ of gauges and cannot adjust charge at 30’ away? Also with anything if 1 tools is bad it don’t take out every tool you have with the field piece. I have field piece tools but anything fluke is very reliable it cost more but very well spent $. Just my opinion like every 1 has 1. 30 yrs tech and service manager of large co. In past. By the way I am not no where near 70.👴 😁😁 learn all you can and go to every continuing training you can. Have fun with it it’s my favorite thing to say I god that right.
Hey Jaime! You can purchase the paperback and/or quick reference cards on amazon through www.amazon.com/shop/acservicetech and we have the paperback, ebook, and quick reference cards for sale at our website www.acservicetech.com I would love to hear what you think of the book after reading it!

I realize servicing companies may find all kinds of uses for the fourth port but the design of the manufacturers was originally that the large 3/8" port was for vacuum when reading their instructions for use. Thank you very much for sharing how your company utilizes the 4th port!

Just finished raising my disable kids and getting ready to go back into the field of AC HVAC .
Thanks because I can't afford to go into debt so I watch your ads or just let them play.
Great channel. Use this to supplement my learning in school.
Thats awesome!
I think I will just stick with the old school compound guages. They get the job done at one seventh the cost and they won't get ruined on a rainy day.
My first dive into digital manifold was a pair of Testo 550s when they first came out years ago. One dedicated to R-22 and the other to R410a (residential & light commercial).

All great points Kenny! Thanks for sharing!
nice and modern tool I want to have.
Thanks vdo sir👍
Thanks Trick!
I'm a big fan of fieldpiece smart probes
Yeah they work great! I like them too, thanks!
thank's partner for sharing excellent video!!!!!.
Thanks a lot Jimbola77!
Your videos are so well done and full of great info,
Thanks so much
Thanks a lot Matthew!

i own the s-man 4.... it is the best out of all the gauge sets
Love your videos ❤️

I use fieldpiece but I hate the clamps. I’m always replacing them
How do you get the 1/8 inch fitting on the gauge to 1/4 inch to fit to the ports?
I guess I am just old💪 I think most entry level tech
Hey sir, do you have a video avaliable for newbie when purchasing equipment?
Hey I want to know the name for a gauge you have in your video

We need a step by step video of how to isolate refrigerant into the receiver !!!!! The whole pump down process !!!!!!
Hello, refrigerant slider very good?
Yeah the Danfoss slider works well, thanks!

Hola , muchas gracias por la información . Realize la compra pero no recuerdo haber escrito mi dirección . 🤦🏼♂️
Those are bloody expensive tool collection. Specially the sman. I would like someday get a better vacuum tool set.
Not accurate information:
We use the larger 4th port to fill industrial racks by connecting the other 3 hoses to charge 3 refrigerant tanks at a time.
I realize servicing companies may find all kinds of uses for the fourth port but the design of the manufacturers was originally that the large 3/8" port was for vacuum when reading their instructions for use. Thank you very much for sharing how your company utilizes the 4th port!
