If your problems are electrical that is much easier to deal with. Also,
don't brush and disturb those evaporator and condenser coils. If they
clog up you either need filters or something to keep the gunk out, but
if you have to clean them use compressed air.

The problem is with clogged ac condensate drain. I know, it happens. But
by me ir happens incredibly often

I've had that with fridges, and solved it by putting copper wire down the drain tube & leaving it in place. It inhibits mould, and is easily wiggled to clear any blockage.
