What a small leakeage can do ?

[Acrisoft]

I installed a R410A inverter unit ( 12000 BTU).

However, by the moment I unattached the hose from valve port, a jet of refrigerant leaked.

I think for at least 10 seconds while I was I unattaching the R410 hose.
( the AC unit was OFF)

It reads 105 PSI g in gauge in a 25 degree C day.

It works normally in cold mode but when I switch it for warm mode it looks
like it does not change. Pipes become frozen at hot mode and
pressure drops from 105psi to about 60 psi.

The question is: Was this amount of refrigerant that leaked enough to hinder
the warming mode and keep the cold mode working, or is this a factory fail of the AC unit ?

Where are your gauge lines fitted in cooling ? The suction and the actual discharge or the expansion line?

Hi

It is a simple unit without expansion valve.

It has only a service port on suction line.

Yes, your release of refrigerant will affect the unit operation.

System charge must be recovered and the correct charge weighed in.
