When should I clean the air conditioner?

pu1. In my case, I tend to clean up, so I do it once in autumn before I seal it, and then again in spring when I unseal it. In the fall, there was mold and dust during the summer, so I needed to clean it, and if I didn't clean it before I used it, I needed to clean it because it smelled like dust

OK

pu2. Should I take a shower before going out in the morning or after going out in the evening? I think it's my personal preference. I do it twice a day

OK

pu4. I think it's ambiguous because it's winter now. I usually do it in the fall or right before I use it in the summer
