In a word, no.
While it may seem like ice should be a normal part of the cooling process, it simply is not. If you’ve discovered ice on the indoor unit of your air conditioner, then it’s time to figure out why. The good news is, this isn’t necessarily a major repair in all cases.
But it is one you should leave to the pros—trying to scrape off or thaw ice on your own could further damage the system, and it doesn’t resolve the problem that caused the ice to begin with.
