Q: I have an air-conditioning unit in my attic, and it is leaking a lot of water vapor into the attic. The ceiling of the attic is covered with mold all over, not just above the air-conditioning unit.
You feel the sting of summer on your utility bill long before you feel it in the air. When your attic leaks, your air conditioner runs harder and longer, yet rooms still stay stuffy and uneven.
