G’day team!
My aircon wasn’t cooling so I decided to do a top up myself.
I got three cans of RF-1234a from my local O’Rileys and rented their AC Gas diagnostic valves to do the top up. As this was my first time doing it, I watch some youtube videos and felt very confident. Until I had finished adding my three cans. I took off the connectors and noticed some green 1234yf on the low side input, when I vented the high side a combination of yf and 1234a gas emptied from the unit under pressure.
I’m assuming the person who rented the valves before me must have used yf and the shop had not purged or cleaned the valves after their return.
My question is, would the residual yf in the hoses and valves be enough to contaminate my system?
Thank you in advance for any advice.
Cheers
Cam
