Vent Portable AC Into Attic: The Pros and Cons
Venting a portable AC unit into the attic can be a viable option for homeowners, but it comes with both pros and cons. Here are a few key points to consider:
Pros:
- Easy installation: No need to drill holes in exterior walls, which can be time-consuming and require professional assistance.
