Great job troubleshooting and fix. Thanks for the video

That install looks like a bunch of Mexican/hacks did it.. work pride has gone out the window

Grest job explaining your troubkeshooting process. Thank you so much bro.

Please send me mail I need your assistance

Nice job taking your time to explain everything so good. Nice job with this installation, you guys know what you are doing at Iron Shield. Thank you for sharing! Keep them videos coming please.

checking these pressures and temperatures at the compound gauge,. first when refrigerant was added and sub cooling went up, but the super heat stayed the same, including the low suction pressure did not increased meaning you have a liquid line restriction , or txv problem,

Thank you so much for the video

To address a low VSAT (Vapor Saturation Temperature) reading, which is an indication of the temperature at which refrigerant evaporates in the evaporator coil, you should consider the following potential causes and corrective actions: Potential Causes: Low Refrigerant Charge: Insufficient refrigerant can cause the evaporator coil temperature to drop. Dirty Evaporator Coil: A dirty coil can restrict airflow, leading to lower temperatures. Restricted Airflow: Blocked or dirty air filters, closed vents, or obstructed return air can cause reduced airflow over the evaporator coil. Thermostatic Expansion Valve (TXV) Issues: A malfunctioning TXV can cause improper refrigerant flow, leading to incorrect temperatures. System Overload: High indoor humidity or excessive heat load can cause the system to struggle, affecting the VSAT. Incorrect Superheat or Subcooling: Improper superheat or subcooling settings can indicate an issue with refrigerant flow or charge. Corrective Actions: Check Refrigerant Levels: Verify the system has the correct refrigerant charge and add refrigerant if necessary. Clean the Evaporator Coil: Ensure the evaporator coil is clean to allow proper heat exchange. Inspect and Clean Air Filters: Replace or clean dirty air filters to ensure adequate airflow. Check Airflow Path: Make sure all vents and returns are open and unobstructed. Evaluate TXV Operation: Check the operation of the TXV and replace if it’s malfunctioning. Check for Air Leaks: Inspect the ductwork for any leaks that could be affecting airflow. Assess Load Conditions: Ensure the system is not undersized for the cooling load and check for excessive humidity or heat sources in the space. Adjust Superheat and Subcooling: Make sure superheat and subcooling levels are set correctly according to manufacturer specifications. Steps to Increase VSAT to 34 Degrees: Ensure Proper Refrigerant Charge: Add refrigerant if the charge is low. Improve Airflow: Clean or replace air filters and ensure all vents and returns are clear. Clean the Evaporator Coil: Remove any debris or buildup on the coil. Inspect TXV: Make sure the TXV is functioning correctly and adjust if needed. Check for System Load: Reduce any unnecessary load on the system, such as high indoor humidity or heat sources. By systematically checking these potential causes and making the necessary adjustments, you should be able to raise the VSAT to the desired 34 degrees.

proof your a hack ! no scale to measure , your a thief ,

what's wrong with your eyes , baggy an dark circles , , why aren't you using manufacturer chart , you hack

Do most techs use this system of superheat and subcooling?

Thanks for your videos im a new technician and this really helps a lot.

Hey brother thanks for sharing. I’m out in Texas in the trade also and you do a great job with explaining the systems functions in a way those can understand. Much appreciated. I have been a lead installer for 4 years but I also do service. Sometimes those Goodman comfort net systems can be a pain because of that firmware. Anyway thank you man keep up the good work

So glad I'm out of the residential field I'd be the one to go back out after someone charged to gas a unit up and I go back to remove a dirty filter or tell them their coil is dirty.

Just subscribed your channel

Do you have your epa 608 certification or diploma cuz I’m in trade school right now I need to know which I need to get

Interesting how MVAC testing is so different. In MVAC, the manifold gauge tells you everything. Superheat and sub cooling isn't calculated. Charts are very common showing operating pressures at different temps and humidity. As well as vent temp.

Low load ,charge is low as well I would bring sub cooling to specifications if specs are not listed bring sub cooling to 7-10 degrees .

That is a little low as well. Txv? You’re lsat is like 3 degrees above outdoor. Should be 15 minimum 8 degrees subcool. You’re VSAT will go up and low side. The indoor temp of 78 will not effect that maybe 65-68 degrees indoor would

looks like an airflow issue possible low heat load, you will be returning to address ice up coil good luck

Are you looking for a leak or just charging. I took a class once and he said never be Dr. Recharge if your low look for the leak.

Very good video. Thank you.

How cold is he trying to keep the inside? Someone told me that your central unit can only cool 10 to 15 degrees below the outside temp. I dont know how true this holds. I prefer window units i can get my bedroom about 68 degrees on a 100 degree day. But my bedroom is on the north side. He needs a freeze protector stat on the evap coil. Its wired in with the 24 volt contactor in the outdoor unit so if it detects freezeing conditions on the evaporator it will shut off the condensor blower will run till frost melts, and outdoor unit will restart again. I worked on a trane unit that was set up as a low ambient unit to cool a server room, and it had a freeze protect device on the evap coil.

You will go back .... to adress air flow

Excellent explanation on troubleshooting!!! Loved it, man!

This is a horrible install

0 DOLLA... MAKE YOU HOLLAAA!!!

Nice work!

All johnson control brands have become total junk...80% have warranty issues.

Did you measure indoor airflow with a manometer? Kind of looked like low indoor airflow to me.

cnt terminal got me laughing a bit there 🤣

Good job Victor

Long time no see Victor. Good to see you again man!

Hey that Guy looks familiar!

Thanks for sharing brotha I’m out in the big easy doing hvac service work for my self also I agree with u to check super heat sub cool

What's up Victor long time lol

Damn thought id never see another victor video glad to see you taking care of business hopefully see more vids comin soon

What's up Victor long time

Like how the builder actually incorporated for the air handler for once instead of putting in the attic

So did you just pump it up and go? With all that caulking, somone must had nicked the line when pulling it through

Victor at it again

Great job victor on this one

Did you change channels? If so, why? Also, how did you come up with the name iron shield? Just curious since it doesn't sound like typical HVAC names
