Anything you get for free is bound to be a disaster. I had been saving my money for a cooling plan in my home. A associate of mine was getting rid of a bunch of window air conditioners. She gave the AC systems to myself and others for free. She did not want to mess with getting rid of them, & I needed the AC. It made perfect sense. I should have considered that free air conditioner that was going to be thrown out would not be the best quality. Now that I have a bunch of window air conditioners set up, I am not glad with them. I want to get central air conditioner still. I plan to continue saving up & then replace the cooling situation. For now, I just keep telling myself to be thankful that I have any AC. The window air conditioners are stained & rusted. They look terrible in my home. Also, the cooling component easily have something wrong with them. Maybe it is the refrigerant or they are on their last legs, and either way, the cooling units all make a horrible grinding sound when on. It is undoubtedly hard to sleep with several noisy AC units running. It is super loud lake house all day long since I can’t stop running the AC units. It is that hot outside. So while I adore having temperature control for once, I hate the air conditioners that are giving it to me. I have literally thought about throwing them out & buying modern portable AC units. But, that would take out of the central AC fund.
