Buying Guide for Through Wall Mini Split Covers
Material Durability and Weather Resistance
UV resistance and material strength are essential to avoid cracking, denting, or discoloration over time. PVC is the most common, offering reliable protection against outdoor elements and chemical exposure, ensuring your line sets are shielded year-round.
Size and Compatibility
Ensuring the wall sleeve fits your wall hole size and the diameter of your mini split’s line set pipes is crucial. Most sleeves range from 2.48 to 2.75 inches in diameter and 8 to 8.66 inches in length, but verify measurements to prevent gaps or damage during installation.
Protection and Pest Prevention
Look for sleeves with caps, plugs, or fillers to keep rodents, birds, and debris out of your wall cavity. Some models offer specialized seals and filters to prevent particle intrusion or improve air quality.
Aesthetics and Paintability
Sleeves with a plain white exterior that can be painted aid in blending with your home’s interior or exterior color scheme. Decorative caps can further enhance a clean, professional look post-installation.
Additional Features
Some wall sleeves come with accessories like decorative wall caps, filler putty, or air filters. These extras can simplify installation and improve system efficiency or maintenance.
Installation Ease
Consider sleeves that are easy to install with included accessories or plug sets. Adjustable length options or easy cutting capabilities can customize fit and reduce installation time.
