Thank you. Yes you can retrofit it to 407c as long as you remove the r22 from the system and start fresh... I'm assuming your talking about the pressure on the low side with r22. With a healthy filter and return/supply air, you should be around 70-75 psi but that can vary with the return air temperature... Hope this helps man, Goodluck
Customer was cool with you leaving and not fixing it then and there? You coulda knock that out so quick, longest part would've been pulling a vac.. Good content tho bro👍
Thanks brother, Your right but what I forgot to mention in the video is that nobody could get ahold the owner for approval or payment and I needed to keep rolling so I wasn't out all night. (first time customer)
