In this spot for Mitsubishi Electric heating and cooling, we see a man fighting a shadow in his own home, and they claim this wouldn’t happen if this guy got the Mitsubishi system.

So maybe that shadow attacking you in your home isn’t due to your energy costs. And if that’s the case, rent your house out to ghost hunters, and you can buy a new house somewhere nice, without being attacked by demons.
