Arrived onsite for no cooling call. Found 2 head mini split system. Head unit on main floor working to as it should. Found master bedroom head unit non operational and flashing lights. The filter door was dislodged. Reattached door and system started up. Ran system and measured 27 degree temperature drop. Please be advised the system requires a maintenance. Also. The blower wheel and cabinet is full of dirt and dust. Blower wheel cleaning on a ductless system is not part of a standard maintenance. Will send estimate for 2 system maintenance.
