Felix E. Cerpa, Sr. says:

Hi,Craig,I have two questions for now the first is when you connect gauges in heat pump where you connect the high hose gauge straight to reversing valve fitting or to fitting of the liquid high line and low side hose gauge to low side vapor fitting.The second question is about the vapor state of refrigerant when you use it and how to proceed to let the vapor enters to the sister.Graig I wil appreciate you prompt to me.

Sem Meh says:

Can I be able to measure with this tool Testo 405i Outdoor DB Temp and Indoor WB Temp, and what is proper way to do measuring on Mini Slit systems. I really appreciate what you doing regarding education us here on YT-.

Dominique Pierre says:

Just i got confused line temp :ambient temp and saturated temp;
Are they same or different.
To be honest ;not great video; the numbers are so small and you did not explain very well regarding temperature.

Michael Lee says:

I am trying to learn how to fix my fridge and a/c by myself. These HVAC guys are blood sucking low life leeches. They want $850 to fix a pin hole leak on the copper pipe and recharge the gas when the fridge is $3800 brand new and $500 second hand. Simply cut and weld a new piece of copper pipe which can be done in 2-30mins plus recharge and testing, I am looking at 1.5hrs labour here.
Good video thx!

hvac have scope plz guide me … sir ….

Gerry Long says:

I bought quick guide troubleshooting card through Amazon. Under TXV Metering device in cooling mode, go to scenario and go down to Outdoor coil: low airflow or deteriorated, it says high under subcooling, I think that should be low unless I am misunderstanding. Could you please let me know? I appreciate all you do and use your info to assist me and my team. Thank You.

In technical school do we do more hands on? Than individual work?
