Hi I have an 18k BTU ductless split installed and recently it was blowing warm air in the indoor unit and cooler air in the outside (compressor) unit. The brand is chigo and it has a rotatory compresor (I think) the mainteinance guy told me the compresor broke down so I bought a new one and still the same thing. It looks like the cooling cicle has been reveresed.

Please help

If this is a heat pump, then yes the reversing valve isn't working. Got a mfg. and a model number?

I believe is not a heat pump, is just cooling (if this makes sense) here's a link to the manual http://www.alliance-tmk.ru/info/folder_manual/chigo/Serice_manual_wall_split_type.pdf the manufacturer brand is CHIGO and the model is kf 61g
