ULTCOVER 2 in 1 Full Mesh AC Unit Cover 36W x 36D x 40H in - All

In this review the ULTCOVER 2 in 1 Full Mesh AC Unit Cover is assessed for homeowners who want year-round protection without trapping moisture. The bottom line: this cover is best for anyone with a square outside air conditioner up to 36W x 36D x 40H in who needs a breathable mesh body for summer and a waterproof top for winter. The reviewer found the hybrid design delivers solid weather protection while preserving airflow when needed, making it a practical choice for seasonal use so long as the unit is not running while covered.

Key Features

• Size compatibility: Fits outside AC units up to 36W x 36D, which covers a wide range of square condenser models so buyers can match it confidently to their unit.
• 2 in 1 construction: A full mesh body combined with a 600D polyester canvas top gives both ventilation in warm weather and waterproof protection when closed.
• Breathable summer option: The heavy duty mesh allows plenty of airflow and ventilation during the summer months to discourage moisture buildup and protect components.
• Waterproof top flap: The foldable top made of polyester canvas with waterproof backing provides a reliable barrier against rain, snow, and hail when secured.
• Service access and piping: A 12 inch hook & loop slit opening permits wiring and pipes to pass through without forcing gaps that let debris in.
• Secure attachment: Flap fastener and velcro keep the top area adjustable for either full coverage or breathability depending on season.

Who It's For

This cover is ideal for homeowners with a square outside AC unit who want a single product that adapts to seasons: the mesh body prevents condensation issues in warm months while the waterproof top protects against winter weather and debris. It also suits properties exposed to wind, birds, and falling leaves where a tough material and straps are useful.

It is not for someone who plans to keep the unit covered while it is running, as the manufacturer warns against use during operation. Also, if a customer needs a fully sealed insulated cover for long-term off-season storage, a different fully waterproof, insulated model may be a better choice.

Pros & Cons

Pros

• Durable materials combine heavy duty mesh and 600D polyester top for long-lasting weather resistance.
• Flexible 2 in 1 design offers breathable protection in summer and waterproof coverage in winter.
• Easy to install and remove, with straps and velcro that hold the cover in place even in strong winds.
• Practical slit opening for wiring and piping keeps installation tidy while maintaining protection.

Cons

• Not intended for use while the air conditioner is running, so it requires removal before operation.
• Fit is limited to units up to the stated dimensions and may be loose on much smaller or unusually shaped units.
