Having my finances in order, I am now trying to improve my homeowner skills and do a better job on maintenance. Thanks to MMM's "can do" attitude, I fixed my washing machine and my leaky faucet. Now I want to clean my air conditioner (having waited until June to use it). However, the youtube and google info I have found offers some completely inconsistent advice, such as "spray with hose" vs. "do not spray with hose." Can someone please advise me on the basics for cleaning my air conditioner? Hose or no hose? Worth getting foaming coil cleaner? Thanks in advance.
