have the system checked for a charge, sounds as if it may be low on freon. It has probably leaked out and will need to be repaired.

Freon and pressure good I was told by tech

if th efreon is full thenyour pressure switch on the evaporator or clutch cycle switch is probably bad or not makking good contact with the evap pipe.

I that something I can fix

i dont' know wht your qulaifications are. and if theis is automatic temp control where you set the temp have a pro look at icause it cold be something completely different

that narrows it down :) Back to square one
