Hi All
I have a Hitachi RAC 2.5kW split that has been steadily reducing in capacity and now won't heat at all. Guages show reasonable static pressure for the temperature but very little rise in heating mode. Compressor is running (sound is normal and quiet) and can hear the inverter ramping up it's speed OK.
Most likely it's dead and uneconomic to repair but I wondered what kind of failure this has experienced?
Probably relevant - when new the system needed to be fitted with a crank-case heater since otherwise it would not start when cold outside.
Any thoughts greatly appreciated :)
Cheers
