HVAC student here. I've never seen a pump down done manually (pressing down the contactor). In the school they taught me to do it with the compressor running on its own. Interesting method of yours. Since you have more control of the situation and do not have to rush to close the suction valve.
It’s better this way, since some systems have a lower pressure cutoff that will shut the compressor off if you run it normally. Therefore you will still have like 40 psig on your low side. But some systems like the inverter/high end systems you don’t really have the choice in pushing the contactor 😂
Great video thanks. 2 things I would love to have you explain- 1)-why did you have to hold contactor in and 2) why did you not close the low side immediately after you reached zero? Thanks so much-I'll be checking back to see if there is an answer to my questions-thanks again-GREAT JOB!
Hi Mark, as I watched in the video, he held the contactor pushed to manually keep the compressor and the fan in the condensing unit and the blower in the evaporating unit "on" so the moment the gauges read "0" he release the contactor and it turn "off" immediately. He didn't close the low side because the moment the compressor stops, the high pressure valve in the compressor is held close by the high pressure of the discharge line and the low side valve is held close by the vacuum in the suction line. It was really a very informative video.
buenas primero déjeme felicitarlo por la forma que tiene para explicar los vides es muy pero muy buena gracias ..me gustaría que también pudiera hacer el video en español por favor para saber lo que dice muchas jarcias
Saludos amigo tengo una pregunta yo hice una recarga de refrigerante a una condenser pero después le quise sacar un poco de refrigerante porque me había pasado entonces cuando empecé a dejar salir el refrigerante solamente sacaba aire y lo intenté por varias veces y nunca salió refrigerante solamente aire sabes porque pueda pasar eso?
This is nice when the compressor works but in the cases it doesn’t you’ll need a recovery tank to pull the refrigerant into before you extract the unit
This is the best pump down video that I've seen so far. He explained the procedure very well.
Agradecido 👍✅ . Por razones personales no pude estudiar a/c de joven; hoy a mis 72 añitos empecé a estudiar lo que toda la vida me gustó 🙏.
Nunca es tarde para hacer las cosas que nos haces feliz. 👍
The pro made a great point about freon in oil and compressor valve...good info
Estoy empezando las clases de aire: acondicionado. En la escuela ;MUCHAS GRACIAS POR SU EXCELENTE VIDEO QUE COMPARTE DIOS LO LLENE DE VENDICIONES
Nice thanks again Paul. We really appreciate your teaching. God bless for what you do to help us .
Thank you man..

@@e-6384 your answer helped me. We all dont get things as fast
It is too late for me to answer, but thank you for your questions and answers..
Excelente técnico, y también aplicó ese método de encapsular el refrigerante con los split
So if I want to do vacum, do I do this step first and run vacum then return refrigerant back to compressor?
You are a great instructor thank you hermano!!!
Tank you, man..

Sir I wanted to thank you for the video I’d appreciate very nice and educational
No problem, have a great time

Gracias acabo de aprender algo que no sabia pumpdown a system 👌🏼
Pablo good to have u back
Muy buenos tus vídeos y me gustaría hicieras este video en español
saludo desde panamá cuando vine a panamá a dar un curso o seminario seria bueno gracias
Thanks. This is easy understood
This is nice when the compressor works but in the cases it doesn’t you’ll need a recovery tank to pull the refrigerant into before you extract the unit
Yes sir you have to recover the freon...
you are exelente tecnition god bless you
What refrigerant?
Can u tell which gas in the system
Thanks good information.
hello , do you have this video in spanish ?
Why do not close the hight port.
I think in this video u not closed sucssion salve
Bunk video. Didnt purge
En donde esta la escuela?
4532 s kolin ave chicago IL
Nice
Como lo traduzco español
Sir AC name
Goodman
😂he forget low side close at the time
Why donot close the low port
Yes if you want to, the compressor reed valves should hold the refrigerant..
