I think you may have a liquid line restriction bud, your SC is high which indicates your flooding your condenser coil / coax coil. A SH / suction line temperature measurement would have confirmed restriction. Recommend checking temperature drop across drier and then honing in on that TXV. You can also see where they middle circuit of your evaporator coil is not sweating indicating an un-even fill rate. It’s possible your evap coil could be restricted as well… a freeze test will tell you if your coil is restricted bud. Keep up the GREAT videos man!
Wow you noticed that
very good brother
Yes the txv could be stuck
I checked the drier and yes the SC was high
Fort Collins CO here. Your videos have saved me so many times. Thanks dude you’re the man. Wish you had merch lol 🫡👍🤘
Maybe I need some merge
I think i'm going to do that
Great idea thank you my brother
I appreciate you watching my videos you are the man
Disregard my lame questions ...lol. I think I figured my way around your direct site.
Hey TAD.... I have BEEN BEEN joined ! A big fan !! I am at a new job , with my first GEOThermals . 12 buildings total (a school) with 2 buildings + a Gym that have Spectra water source heat pumps . I could really use some of that Geo training and literature. I really only know how to like and subscribe on you tube with out some sort of outside links to virtual stores . Hoping tiers of membership or purchasing materials can be explained in an Email . THX so much for what you do !
Hey brother
Click the join button. That will allow you to join as a member, and it will give you my email.
Then I can send you some geo guides
If you join level three membership, you can have access to my geothermal training videos.
@@TaddyDigest Just let me know how to set up the monthly fee for Email , I’m guessing that’s tier 1 ?
Sorry I am not well versed
In you tube at the user membership level.
Thanks for the response.
I love this guy
Tad awesome video. I am on my second geo unit, first one lasted 25 years Hydro heat open loop workhorse. I am mostly a DIY person and enjoyed your video. Also subscribed.
Very cool!
Thank you so much for awesome videos with great content
Glad you like them!
Hey Tad, I had a situation like this today. System was low pressure put about 3 pounds of our 410 a in the system got an 8° sub call system is working no issues could not find any leaks possibly the Schrader cores leaking but this mild temperature weather and high humidity is really throwing these pressures off just part of what we do, but good work, Tad
Nice work!

I joined Tad!
excellent news here is my email tadfuller1@gmail.com
I have a carrier 4ton about 7yrs old Freon level is good just clean coli n condenser new thermostat new dryer only thing not oem is fan motor but during day does not seem to shut off when it reaches 77 set on thermostat evening nights yes. Any idea what to check or change Im out of ideas on what it could be ? Thank you in advance.
I joined and need the geothermal training
Awesome Thank You Here is my email tadfuller1@gmail.com
Thanks
I have 1000’ of vertical wells I had a service company come out about 3-4 years ago system went down. They added water to the loops not much. They said it was from expansion and contraction of the ground loops over time they may need a little water. My question is it happened again and I added some water. Should I be adding antifreeze instead of water? I know initially they added some kind of glycol-water mixture when system was built. I am worried about loops freezing
Hey I hv just joined, send the guide pliz. Be blessed.

My 18 year old FHP unit just had a no cooling issue. I checked pressures and found it to be low on R22 (around 45 psi on the low side) so I added around 1 pound. The pressures came up to the 68 low 220 high range, but then the evap stated icing up. I got my loop pressure gauge and found the inlet loop to be only about 8 psi! I used my gooser and added water until I got around 40 psi and the evap started melting and got good 48 degree discharge air. Without knowing proper loop pressure, what should static pressure be and what temp difference should i see across the loops? Great vids and information! I subscribed and joind! Thanks for the GEO guide.
Awesome jerry good job my friend you are doing a great things.
Static pressure for the duct work external static pressure should be point .05
Loop pressure should be anywhere from 30 - 50 psi
@@TaddyDigest Thanks for the quick reply! After watching your videos, I realized I needed to charge off of SH and SC instead of just gauge readings. I bought a used SMAN360 and with your guidance I can now make more sense of what I need to do!
I still am curious what amount of loop temp change I should see if things are working correctly?
Thanks again for sharing your knowledge with all of us!

Im a level one. Would love the guide.
excellent here is my email tadfuller1@gmail.com
what's the coaxial function?
To transfer heat from the water to the refrigerant
It acts as the condenser during the cooling operation and as the evaporator in the heating operation
I've joined a while back. Hope its not to late to send me your geo guide.
You're a member. It's never too late for you, my friend. Thank you for your support. Here is my email tadfuller1@gmail.com
I joined can you send me the geothermal training thank you
Yes absolutely thank you for joining
