Hi,
ive a 25 year old hitachi split ducted im looking at :
the indoor TD never gets above 6 degrees
the sub cool fluctuates between 4-11k (1500-1800kpa)
superheat fluctuates between 1-10k (450kpa)
Its in a confined area with other condensors so the head pressure was a problem until i cleaned the coil.
Im thinking ive got air in the system or the ambient temp fluctuates with the other condensors cycling on and off,but that shouldnt keep the TD so low if its got a correct charge.....?
Any advice is appreciated.
