🏢 New Construction vs. Retrofit Considerations

New Construction:

• Full flashing/sealing possible at build stage

• Choose sleeve depth to match final wall thickness

Retrofit:

• Watch for corrosion, warping, or water damage

• Replacing sleeves may require siding or facade work

💡 Tony’s Take:
"Don’t reuse a 20-year-old sleeve just to save a few bucks. Bad sleeves destroy good PTAC units fast."
