- Material and Durability: Look for galvanized steel or stainless steel with weather-resistant coatings to endure rain, snow, and sun exposure.
- Insulation and Sealing: A sleeve with good insulation reduces heat transfer and improves AC efficiency; check for seals around the unit.
- Ventilation: Proper ventilation helps heat dissipation and prevents moisture buildup; consider sleeves with ventilation mesh or grilles.
- Debris Protection: A sleeve should block leaves, dust, and insects while allowing airflow where needed.
- Weight Support: Ensure the sleeve can bear the AC unit’s weight without warping or shifting over time.
- Installation Ease: Consider sleeves that align with standard TTW dimensions to simplify installation and reduce modifications.
- Maintenance Access: Choose designs that allow easy inspection of interior/exterior areas and drainage maintenance.
