What a tedious job to do, especially 4 indoor units. Took approx 1.5hours each to strip down and put back together. Given that most wall mounts get like this you would think they would make it easier to get the fans out. I had to strip the unit down completely only thing left was the coil which lifted off its mountings.
Someone needs to design a wall mount where the fan is placed before the coil so that it's not being in the cold then when the unit is switched off left in the damp. My units are all set with the dry feature turned on that rotates the fan for 20 mins after it's turned off to dry the coil out. Mould covered 3/4 fan scrolls. The units have been installed for nearly 3 years and are cleaned yearly and filters cleaned every month in the summer. This mould makes the idea of air conditioning quire dirty to think it is is blowing air out like this.
I cleaned with coil cleaner and a solution of bleach to ensure nothing was left. They will prob just get as bad. Heating airflow is massively improved now though. I am wondering if having constantly recirculated air adds to this problem. Maybe I need to increase fresh air in the cooling season?
What if anything do you do to prevent this?
