I had a new system 3 aircon installed in first week of July. The 1st month was fine. But after that, for the past 2 weeks, all the indoor fan coil units are no longer blowing out cool/cold air, only room temperature air.

Asking the installer's technician to come down take a look.

What might be the possible problem? And how come the problem takes some time to surface after the installation?
