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 :)
