Besides routinely changing my filters, should I use my garden hose to spray
through the a/c that extends through my window from the outside. Someone
suggested I do this at the end of the season to flush out pollen, feathers,
leaves etc.., but I fear rust :) How should one clean an a/c?
Also why does more air seem to flow from the right vents of my Friedrich a/c
and not the left?
Thank you wise friends :)
