If it'll switch ECON on/off then the HVAC unit thinks there is enough gas, which comes from the pressure switch on the evaporator.

Its becoming increasingly common for the valve blocks to fail and allow hot water through constantly, meaning even if the AC is running ice cold, you still get a face full of hot air. Marcel and I are working on a solution for this which is not tested yet.

Is the electric fan on? Yes, running fine.
Is it cooling at all? Not cooling at all, fan on high speed.
Condensation on the pipes past the header tank? No condensation, pipes appear to be warm to touch.
Is the centre vent switching between hot and cold? No discernible difference when switching from warm to cold on centre vent.


Am I looking at Valve block replacement or finding a learned AC person?
