I’ve seen a bunch of complaints about intermittent or weak A/C, especially on hot days. I experienced this on day 2 with my R1T, 95+ deg day in Massachusetts.
Turns out my refrigerant reservoir was filled to the R1S spec, and thus over-filled.
Here’s what I experienced: At first the A/C worked fine, but as the outside temperature increased it became noticeably weaker to the point it was blowing hot air. I tried a soft reset and then a full reset hoping it was a software issue. Still hot air. Hours later as the temperature dropped I started to get cold air from the A/C again.
I brought it to the service center and luckily the software had logged an overflow event (paraphrasing). Importantly, I knew exactly what time I had starting blasting the A/C and noticed the problem. This was critical because the logs are long and they were able to pinpoint the time the error was captured. Essentially with an over-filled reservoir, on a hot day the refrigerant had expanded and leaked out and the system stopped working. They flushed, refilled and pressurized the lines. It’s been a few days now and everything is working much better. Noticably colder than when I took delivery - I was too excited to notice the issue until I was home!
I just wanted to make sure this was documented in case someone experience this strange issue. Every tech is different so make sure they check the fill level!
