THANK U FOR THESE VIDEOS. U have no idea how much easier school is now. I can only learn so much from the book and I’m the kinda student who needs one on one so thank u bro.
Awesome videos. I’ve had two heat pumps on maintenance calls lately and really knew nothing about them, mostly because we don’t see many, but this was very informative!!
I appreciate you man for this ! I’m in the field got outta school in 23 but best I got outta school was this ! That txv is like a hole it opens and closes but man i appreciate you for explaining this
At 13:28, I noticed that the suction pressure went into a vacuum. I heard the audible noise from the compressor sounding like it a mechanical clank. You ended up condemning the outdoor TXV since there was no temp drop between the outdoor TXV. Reason could be is that the outdoor TXV opened up all the way due to sensing bulb not sensing proper suction temp since the suction was in HG. In this fact would case no difference in temp across the txv which in normal conditions should of caused a superheat temp difference if the TXV was sensing proper pressures. In this case it could of been that the reversing value wasn't switching properly. The only reason why I say this is because when you did the changeout, there was only a 3 degree difference since the audible noise is gone and proper pressure are present. As well, your hot discharge temp was only 71F. Clearly the hot gas wasn't leaving the unit. Wouldn't the outdoor txv be the least of your worries since that's AFTER the unit subcools the hot discharge inside the air handler? I believe that this was fixed after a proper vacuum and proper charging procedures oddly enough.
The outdoor txv could be plugged on its internal bypass or plugged in metering device operation . In this case it wasn’t causing a restriction in cooling but in heating during the metering device operation it was plugged and causing a restriction . The reversing valve is not the issue .
If the reversing valve wasn’t switching properly you would see a temp differences in ur two suction lines and the hot gas would be bleeding over to the suction gas because of pressure/ temp difference.
@@fazesenso2864 The reason why i’m confused is that the Txv didn’t show a drastic difference in temperature if it were to be plugged. It actually showed the same temperature.
If you took ur red hose and put it on the liquid line port In heating . Wouldn’t you see a high pressure then the discharge ?? Because we aren’t metering past the outdoor txv ??? And all the refrigerant is built up on that side of the system ?
Any clue why a mini split wont blow cold air and heater wont work or blow but the fan mode does we had it recharged but 20 mins later its gave a code el oc and heater gave CF( but its brand new straight out the box even had a pressure test and everything was good would appreciate it so much for a reply !! ASAP lol
@@cesareolopez7222 Hey, I am a tech but i was hoping my comment can serve you well. Im assuming you're using a MR cool since your error for CF is a main anti freeze error for mr cool mini splits. If you confirmed that your refrigerant levels are proper and weighed in properly. PS Please make sure you watch the pressures actually stay steady on the suction when its running it cooling. CF error code for heating is simply the Anti-Cold Air feature in action during HEAT mode. This feature prevents cold air from blowing into the room until the system warms up. Since you're getting this error code, it does seem like you are running low on refrigerant. Please confirm if you weighed it in. Now if you did and continue to get this error code. Check your coil thermistors, they may be faulty and causing it go on a lockout.
hello, can you please help me im going crazy,im from europe and i have a fuego 12000btu ac split heat pump,ac doesnt really blows hot air in door unlike my father's ac which is a midea,my ac uses r22 so yes its an old system but i dont get it why it doesnt blow hot air everything seems to work fine defrost works fine fans work fine but the air that comes out its not hot but like lukewarm air if i may say,please help me im freezing in my room😅

Absolutely.You're very welcome, my friend.I'm glad you liked the video
@ taking my electrical test tday for HVAC so keep me in ur prayers lol.

Great job. Keep ‘em coming.
SO GLAD TOO SEE U BLOWING UP BUD IN SUBSCRIBERS AND VIEWS KEEP UP THE GREAT WORK!!!
Excellent explaing format. Very easy to absorb. very concise yet doesn't sound like you are reading from a book.
Wow, thanks!
Good video Teddy 👍
Best freaking video EVRRRRR👍🏽. NOW I KNOW HERMANO
Thank you for taking the time to educate us and making the information clear
Glad it was helpful!
Great video.
Thanks for a great video! Whatndoes TXV stand for?
Great noleg boss
Love the video but shouldnt that filter drier have been changed being after the system was opened up?
Yes, absolutely.You are one hundred percent correct
Do more heat pumps
Great explanation of the TXV
Glad you liked it
Very helpful, thank you Sir 🙏
Great video. Thank you for sharing.
Thanks for watching!
Hey still didn't have a temperature differential on that TXV you put in?
I didn't keep my probes on the t. X v long enough to show you.That's one mistake I made in this video
O k thanks for the honesty
You're welcome absolutely
You like the manifold you’re using compared to the others?
This is the best one i've owned.I love this pair
Nice job bro
Thanks
Who mades those temperature clamps?

@@fazesenso2864 I see your point but how come hot gas was at 71F when this was happening. Besides the txv probably being restricted.

Taddy the tech
As always great thanks 🙏 you 😊
So nice of you
Thanks!
You're welcome. Thank you so much for your support. I really appreciate you.
If you took ur red hose and put it on the liquid line port In heating . Wouldn’t you see a high pressure then the discharge ?? Because we aren’t metering past the outdoor txv ??? And all the refrigerant is built up on that side of the system ?
Yes absolutely
So which way is the correct way to measure pressures in heat mode with an outdoor txv?
would nice to see a thermal imaging camera used, maybe in future video?
A great idea.I can definitely make that happen
Great Video!!
Thanks!
So in heating mode you should never connect to the liquid line?

Commented here because was most recent video and saw a previous one about you👌👌

oh and there are hissing and bubbling noises when it goes in defrost mode is that normal?
Get some gauges, hook them up.See what the pressures are
It's probably low of refrigerant
@@TaddyDigest its a non inverter btw,thanks very much for the advice,will do❤
called the technicians,they will come thursday since my ac is still under warranty lets see what they will have to say
First!
Excellent i'm glad you're here
