The DOTS HVAC Troubleshooting Simulator needs to be a bit more realistic. Next video... when you remove the Electrical Cover Panel... Have a simulated Copper Head Snake bite you. Video narration says: "Move the cursor over to the toolbox, and click on the tourniquet. Quickly place the tourniquet on the affected limb by clicking above the snake bite. Next, click on the button that reads: CALL 911". Congratulations! You have successfully completed this simulated lesson.
I think its important to mention the type of refrigerant you're using since that will effect the starting pressure. Here you went 95*F and added 20*F (O.A.T + 20*F = 115*F PSIG) which for those new to the trade that means the refrigerant used in this system is likely R-410A.
You never took a subcooling temperature before you said it was low on charge, so how do you know it isn’t a partial restriction? Should have just used the testo guages in the tool box, it would have showed you all of that
Hi Rod, were you using the Cengage simulations or SkillMill™? If you'd like, you can sign up for a free trial on SKillMill™ here: www.interplaylearning.com/pricing#free-trial
Why didn’t you just use the Testo gauges to get subcooling and superheat readings, so you could determine if the high superheat reading is due to a refrigerant shortage, or a restriction? If you don’t take a subcooling reading, how do you know the charge is isn’t bottled up in the condenser, due to a partial restriction? I’m really surprised, as an instructor, you didn’t mention how to determine the difference between a refrigerant shortage VS a partial restriction. Technicians adding refrigerant over a restriction is a problem in the field and is the cause of a lot of compressor failures.
@@InterplayLearning you missed the point. If I understand the original question, he's not saying you have to use the digital gauges, but he does question why you did not check subcooling at all, with ANY method. Therefore you are not certain the high SH reading is due to low charge.
Have you heard about using Cold Plus refrigerant additive to get colder air and use less electricity? I heard that both commercial and residential units are saving between 8% to 18% utility bill savings...is that possible?
Regards. I would love for a technician who did service in the 80's, 90's to give his opinion of how this was repaired Same problem at the time? ... without them they repaired the same. Maybe the problem is that you did not require an EPA certificate. What I mean is that there were not all these tools back then and in this video they are shown as essential. You do not get them so cheap, the companies do not facilitate you to buy them. These videos focus on selling tools to young technicians more than anything.
Hi Mariano. Our instructor, Tim Smith, has actually been in the industry for 32 years. Have you looked at any of our newer videos? Our simulations have evolved quite a bit in the past 5 years.
Where's the video where you have to deal with a customer yelling at you when you tell them how much R-22 they need and it's going to cost them almost 1K. P.S. stick with yellow jacket mechanical gauges, testos suck.
i am retired for years but i been seeing change over to 407c from r22,,,,,just saying ,,,,, in 2020 i am still holding on to a brand new cylinder of r22 and 1/2 of a used one ? may never use them ? i would have to find a r22 ex valve on a new unit i imagine ,,,,thanks , stay safe
seem outdated. a realistic HVAC simulator will be great. with today high tech graphics. with to date info, hardware. if you look up PC Building Simulator. should be as close as possable to that.

I love your method of teaching and your videos are great.
As a newbie in college i got an awful lot from this video. Thanks very much
I did 5 yrs college to work a miserable job 7 days/wk and HVAC would have given me a much more pleasant life.
Real demonstration from real experts!

lol this and a swarm of bees
Would love to see this simulator on STEAM!
I agree maybe a HVACR refrigeration simulator 2023 action maybe to see if someone may want to attempt it as a real career?
"fix leak" hur hur hur. There's a whole lesson in just those two words.
Very useful training. I like the interactive feel.
That's great to hear!
Thank you for the information that was very helpful
very helpufully
Excellent video
Thanks, Pablo!
Nice demo
Thanks marcibb!
If you dont have a chart for superheat just do: WBx2 - 80 - Outdoor Temp / 2
70x3-80-90=40/2=20
OJAI what??

R22......
so damn good
Great Video!!!
Thank you!

wish i had a "fix leak" button with me to click ;) pretty cool. great class! thank you! and where do i get some tests to take? :)..
I subscribed how do I do the interactive troubleshooting?
We used the interplay simulator in our apprenticeship program. There are some bugs in it. It’s not perfect.

good explanation....mentioning the refigerant would be fair..
good video thank you
Very informative and helpful
Can you translate your videos in Italian please???

Testo gauges were added after the video was produced. Same result using a standard gauge manifold and thermocouple thermometer.

You guys are from the dutchess county area ??

Tom Warda if it’s not oil or refrigerant then its a contaminate.
good explanation!!!!
Good
This is what I'm talking about
pt chart clearly states r22

TU...dang all i need now is the license. i know more about this than a lazy moron that came out and didn't check
any shit for 250.

JB gauges are just better !
The field piece SMAN480 is a nice manifold.
