i would like to see video of people actually using it on the field like testo and fieald piece and checking realistic distance not a foot ball yard

i really appreciate what you guys are doing for the industry.......

I've seen my lines frost over while pulling a vacuum during cold weather. I assumed the frost was also forming on the insides of the liquid and suction lines.

Can you use measure quick on vrv systems ?

Wicked good video Thank you

But what if we have a dirty condenser coil and low indoor air flow? In that case we would flood the compressor I think. What do you think? Thanks.

Great session! Thanks guys

Keep the pay wall this way cause from the comments it looks like it’s getting rid of the guys that really don’t care about actually making systems run to their proper capacity but just want a pretty picture they can show their customer that the customer doesn’t understand.they definitely don’t want something that shows their system is running at a D- 😂

The fact that ANYONE asks what’s free is gross. The amount of time and brain power they put into this and you want it for nothing? 🤯

Hey Joe, what about the discharge line. 😂

This software saves me hours of time doing math and guessing. It usually gets it right on the first or second fault. It has helped me immensely. Usually it describes the exact problem I I’m thinking and sometimes it surprises me. Some people think this is a shortcut, yes and no. It teaches you too. I spend less time on a service call often. Thanks for this!

Great info. to know. Thank you, Jim.

We love Jim. 😂

Twice in a 40-year career on water cooled, R22, TXV systems with low airflow I witnessed such severe flooding that the discharge lines were heavily frosted. The first one was a 100-ton Carrier system, the second was a 5-ton Chrysler Airtemp system. The compressors survived somehow. I swear that this is true. I never saw anything close to that on air to air systems.

Thanks Jim.

I appreciate your contribution to moving the industry forward Jim. The MQ app is fantastic, recently it keeps saying the “seer rating is not possible”. In the real world the seer rating is almost never possible.

Great video.

If you increase airflow and the charge boils off quickly, why is there no superheat? Seems like you wind up with all vapor so no risk of liquid to the compressor.

Love these scenario training videos. Thanks Jim! Looking good too 😎

….got a little bit out of this video? No, but a whole lot. Always looking for your videos, and always impressed how well it is presented. Beautiful!! Thank you Jim. I’m wrestling with low SC and low SH. Suspecting an oversized piston. Perhaps I should increase the blower speed?

It took me a while to realize the behavior of a "fixed" metering device is dynamic due to changes in the high side pressure. On a hot day when there's more load on the system pressures will go up and more refrigerant will go through the fixed metering device. In the experiment you ran, the high side pressure dropped, which lowered the amount of refrigerant going through the piston which helped the system stabilize in the low airflow condition.

Can we please get a subscription service for the app instead of buying qbits!

Awesome video

❓The other day i was getting about a 10psi difference on the mQ app compared to the Field piece app. Put the gauge on it and the field piece was accurate. Why would i get different readings if they have the same source?

How about you just be a master VRF tech like me and stop relying on an app to think for you? Jk that app helped me learn so much I don’t need it anymore. Teach a man to fish.

How can you tell if your fan speed is too high if you don't have an anemometer? And will a too high fan speed raise the evap pressure too high on a perfectly charged system?

i wish more guys would watch your videos a lot of good knowledge and helpful to understand why we need to do things

perfect time to hear this I have an AC service check in 13days. Thx for posting this

Does MQ work with the Appion PTC 900 kit?

This are the videos that make want to go back to measure quick. A long time has been since I see a video like this thanks.

The anemometer measures air velocity that needs to be averaged over the area of the leak. You went directly to CFM. Did I miss something? The temperature of any air bypassing the evaporator also matters on a real job.

Well put !!

Use your eyes Use your ears. Fix issues that are apparent before the gauges come out. It's not a waste of time

Good points, great info. Thank you, Jim.

Curious what MQ estimated airflow was? Also have you made any content wi MQ and the testo 429 flowhood?

Sometime you have to just accept real world conditions.

Jim, I appreciate your knowledge, and your dedication to the HVAC industry. Truly, you are a great asset. Thank you! ❤

Thank you thank you for making this video. I’ve been trying to push and stress this message that if your airflow is off and your readings look perfect. It’s all really wrong.. But I’m just one little tadpole in a mud puddle

if u have not did one maybe do a system that was working with oil in system ,then let that system open and show how much longer it would take to get a vacuum

Excellent

Thanks Jim

Boomer techs are mad that they haven't have this technology like Gen Z techs do.

Great discussion and info. Thank you, Jim and Ty. We need more like this.

Airflow has been and probably always will be the most misunderstood thing in hvac since hvac began. If residential hvac took a more commercial approach to design then it would be better but chuck in a truck will always keep that from happening at any scale.

Lov😊e this. But even when I test and measure with equipment with a dialogue, recording showing some of the old geezers who need a trip to the glue factory, they still deny and believe their way is right . It’s like they’re on a Jadi crusade I’m passing on bad information to the next generation and they stand behind it. 🤦‍♂️ Our Gene 🧬 pool needs cleansing 🧼

I just happened to scroll past this and happened to see you here Ty! I loved learning from you and still remember sh and sc , and remember how passionate you are.

Not one of those comments were wrong. If your digital devices fail to work - dead battery, app won't load, tool won't work, you need to know how to do the calculation for sh/sc, but also understand what the numbers are telling you.

Again, another great presentation. Thank you!

Boomers like this are the worst

Measure quick seems to block screenshots. Why?
