Service Checker Data Analysis - Low Ambient Heating Issues

In this video, I delve into the intricacies of HVAC system performance, focusing on key data points like discharge temperatures and superheat. I explain the significance of various modes and control settings, highlighting the critical role of defrost cycles. By analyzing temperature readings and subcooling levels, I uncover potential issues such as charge imbalances and compressor strain. Viewers are urged to pay attention to crucial indicators like discharge superheat to ensure optimal system operation.

Excellent video with invaluable information, Roman!

🤯🤯🤯 great training video as always roman 👏👏👏

Hi Roman, great and simple breakdown of how to navigate and use the Service Checker. Love this. In 29:13 minutes you show an animation how can I download it ? Is it through service checker?

My mind is blown, glad I'm not the only one whose brain has turned to mush staring at SC data and not having a clue at what I'm looking at and what to look for. Also, your right, today was one of those days I seriously considered sending my application to Walmart.

Great video Roman.
Mind blown! 🤯
I would like to send you some scenarios that I find as well when we have a system that has more capacity tonnage on our fan coils then our outdoor units. (135% Connection Ratio) the data can get confusing at times when we have a full 100% call for heat on our fan coils.

Brain officially explodes! 😅
Great video again

Great info! Would be interested to see you go through a unit that is running correctly

Hi Roman, I've got a system that has killed 2 compressors so far. Just finished up the replacement of both and a full cleanout of system installing bypass loops for filter dryer cannisters. I know its common with the contractors nearby not to update web-express reports and simply going off the orginal for final charge numbers.
While reviewing data most things seem normal except when in dual operation Oil Return my DSH shoots up to 90-100* for several minutes. Is this normal? Also SSH hovering right around the 30* range. Happy to send you data. I've got 65 hours logged

Awesome video man! Is that refrigerant flow diagram just a PowerPoint? Can it populate live data?

[Ridehighfxdb]

Holy crap I’ve never seen a discharge pipe temp that hot before. Hottest I’ve ever seen in the field is like 212

Thank you for the great and informative explanation! I noticed the software you used during the explanation, which seems to be a simulator for the refrigeration cycle. Could you please tell me the name of this software and how I can access it? Also, were the refrigeration cycles included designed by you, or are they built into the software? Thank you so much for your time and effort!

Wow Great Job, The VRV diagram how can i get that. I'm currently building a VRV HR air to water system,

[dylb]

Keep them following! How do I email you data?

Carbonization of oil is bad. What about adding oil instead of replacing compressors? Assuming the compressors are still in good shape.

It's gonna be a game changer when we can get AI to look at the data and give us an idea what is going on with the system. It'll be able to continuously learn and remember each problem it runs into and use that data to better help diagnose.
