Once it’s in, clean the filter every month. A dirty filter makes your AC work harder than a hamster on a wheel. Also, check the outside grille for leaves or debris. Nature likes to clog things.
If you hear weird noises, don’t ignore them—it’s your AC crying for help. A loose screw or a clogged drain can become a bigger issue. Fix small stuff so it doesn’t become a “call the landlord” disaster.
