If you’re planning to install a through-the-wall AC like the Amana PBH073J35AA, you will need a wall sleeve to ensure a secure, leak-free, and energy-efficient installation. Mike Sanders explains what a wall sleeve is, why it’s essential, and how to choose the right size and type for your AC.
🧱 What Is a Wall Sleeve?
A wall sleeve is a durable metal or heavy-duty plastic box inserted into your wall to support and house your through-the-wall AC unit. It acts as a frame, providing structural stability, weather protection, and a secure channel for drainage and ventilation.
❓ Why Do You Need a Wall Sleeve?
✅ Supports Weight: Holds the AC securely in your wall without damaging the structure.
✅ Prevents Air Leaks: Seals around the unit to prevent drafts, moisture, and pests.
✅ Manages Condensation: Allows proper drainage to prevent water damage inside the wall.
✅ Improves Efficiency: Sealed installation reduces energy loss.
✅ Eases Maintenance and Replacement: Makes it easier to remove or replace the AC without damaging the wall.
