How often should you clean your A/C evaporator coils?

Grumpty's answer
Every 12 months
Why bother
Furred-up coils make it cool less and cost more. A thorough-tier job. Skippable when life's busy, worth it when it isn't.
When to start thinking about it
Give yourself about 7 days' notice. That's when Grumpty starts grumbling, so it doesn't land on you the day it's due. Mark it done and Grumpty sets the next one, every 12 months, so you can go back to forgetting it exists.
Let Grumpty remember it for you
Add it once. Grumpty tracks the date, grumbles when it's due, and rolls it forward the moment you mark it done. No spreadsheets, no sticky notes, no forgetting.
