🧱 1. What Is a Wall Sleeve (And Why You Need One)?

A wall sleeve is a metal or composite casing that gets permanently installed in your exterior wall. Your through-the-wall air conditioner or heat pump slides into this sleeve — not directly into the wall.

✅ What It Does:

• Supports the weight of the unit

• Protects against weather, pests, and condensation

• Reduces vibration and noise

• Improves efficiency by sealing gaps

• Simplifies replacement later (just slide out the old unit)

🚫 5. Common Wall Sleeve Mistakes (and How to Avoid Them)

❌ Mistake #1: Wrong Size Sleeve

• A sleeve too shallow won’t fully support the unit

• A sleeve too wide leaves air gaps = inefficiency + bugs

❌ Mistake #2: No Tilt for Drainage

• Always slant the sleeve slightly downward

• Prevents internal moisture buildup

❌ Mistake #3: No Sealant

• Gaps around the sleeve = air leaks, mold risk, energy waste

❌ Mistake #4: No Grille

• Leaves the back exposed to birds, squirrels, rain, leaves

🧠 Mark’s Advice for First-Time Installers

“I see a lot of homeowners skip the sleeve or stuff their AC into a hole with spray foam. Don’t do it. The sleeve protects your wall, supports the weight, and makes your install last 10–15 years. It’s a small investment that makes a big difference.”
