Sadly, that does seem to be the case.
That said, I will get this unit running if I can get past two remaining obstacles; 1) finding a source for .022" cap tubing (going to .026" doubles the needed length) and 2) figuring out how to jump the thermostat wiring to get the unit to run so I can benchtest it before sinking $200 in a control unit.
It is worth the time/effort IMHO given the unit was damaged during its initial installation
, meaning the compressor unit has 0 hours.
Regarding manufacturer's support, would you agree that things would be a lot better if they 1) include a service port because it is not reasonable to think someone should junk a $800-$1300 system because it is low on refrigerant, particularly one that had quick-connects in the design, and 2) make technical drawings available on-line so that the hourly rate or at least the overall cost to have them serviced would go down.
These two changes in the industry would make me want to buy these high dollar products with confidence that I am not throwing my money
Just my $0.02 in case a manufacturer is reading.
