Hi everyone,
We just moved to Lewiston ID/Clarkston WA. It was very hot and so decided to order and install a mini split air conditioner. Install went OK, and it seemed to work for about 3 minutes, but since then it fails with a P3 code and blows warm air. I am assuming there is no longer any refrigerant. We did cut the line and reflare the copper tubes during install because the ones shipped with the unit were too long. I'm assuming that is where the problem occurred.
Before turning it on, we pulled a vacuum on it for about 15 minutes. It seemed to draw a good vacuum, but I didn't have any way of disconnecting the vacuum pump to see if the pressure would hold over time, so there very well could have be a slow leak. The evidence sure seems to indicate there is.
At this point, I have called around to everyone in the Clarkston/Lewiston area and nobody will look at it because it was a self install.
It's an R32 unit, so I don't have the equipment to work on it myself. I understand the theory behind A/C, and work on the unit in my car, but I don't have experience with these mini split models or R32 in particular. The installation manual did not come with any tables for the appropriate pressure we should see, or how much refrigerant to fill. Is there an industry standard for this? It's a 24,000 BTU model.
Can anyone suggest what I should do now? Does anyone know of a tech in the Lewiston ID area who will take a look at it for me?
Any advice is appreciated.
Best Regards,
Chris Ziomkowski
