I have an innovair 24k btu inverter minisplit. I installed it 10 years ago before minisplits gained much popularity. So there's not a lot of documentation or service information available on this particular unit.
Now, it's not getting cold, only cool. I don't have net good measurements, only the measurements I have taken when it's acting up.
Inside unit is showing ~60f at the coil. My other ac unit at the other end of hte house is showing ~35f. The problem unit typically is able to cool the house in about 15 minutes, extremely well.
It is a r410a system. I have a 2lb bottle of 410. I think the issue is the system is low on 410, everything else seems like it's operating as expected.
If it's low, what stage do I add it? And what are my target numbers?
If it's something else, what might it be?
It starts at 120psi.
When the compressor kicks on, it drops to ~40-50psi.
When the compressor kicks off it jumps to ~220psi.
Then it equalizes from there to ~120psi.
