minisplit as maintenance


On my high wall mounted (ductless) mini split ac unit, i have noticed that even though the air filters are clean, and aluminium fins in the unit are clean as well, the blower unit collects a lot of dust which attaches to it, my question is, if there is a practical way to do cleaning and manitenance to the blower, without having to take down the whole wall mounted unit?? can you please describe the process, to open the inner console and extract the blower to be washed and put back in place......? i will certainly appreciate this information since this means a better air quality for all users-

They can be very tricky to take apart. May want to get a Pro to do it. If you loosen or break any plastic pieces you may have a permanent rattle later and wish you never set eyes on the thing. Try blow it out with compressed air and have a shop vac running at the same time.

minisplit as maintenance


Our wall mounted units(city-multi) started throwing off funk, or blowing chunks, whatever you want to call it, recently. The blower wheels where coated with debris. The HVAC guys had to remove a lot of stuff to get the wheels out. Something happened to one of the units during the procedure and it still isn't working. Happens to be the one in my office, of course. There are lots of small wires and expensive circuit boards in these critters, so be careful if you decide to have a go. Maybe get an illustrated parts list before you start.

It was a job. I think they need better filters to avoid this sort of problem. The little screens just don't seem up to the task.
