Indoor Window Air Conditioner Cover (17" x 13" x 3.5")

Key Features

  • Dual-Layer Insulation: Constructed with a high-density polyester fiber fill sandwiched between durable fabric layers to effectively block cold drafts and prevent heat loss during winter.
  • Adjustable Velcro Sides: Features reinforced Velcro straps that allow for a snug, custom fit around the AC unit, accommodating side brackets and power cords without compromising the seal.
  • Draft & Dust Barrier: Specifically designed to stop cold air from entering through the AC vents and to prevent dust, soot, and allergens from accumulating inside the unit during the off-season.
  • Condensation Control: The breathable yet insulating material helps reduce moisture buildup on the interior of the AC unit, protecting internal electronic components from corrosion.
  • Machine Washable: The brown polyester fabric is fade-resistant and can be easily cleaned in a standard washing machine for multi-season use.

Technical Specifications

  • Dimensions: 17" Width x 13" Height x 3.5" Depth.
  • Color: Chocolate Brown (Neutral aesthetic to match interior decor).
  • Material: Quilted Polyester Fiber Fill / 210D Oxford Fabric Shell.
  • Mounting Type: Slip-on with elasticized edges and Velcro tensioners.

Compatibility & Fitment

This cover is designed for small window AC units (typically 5,000 to 6,000 BTU). It is compatible with many standard units from brands such as:

  • Frigidaire: Fits standard FFRA051 series 5,000 BTU models.
  • GE & Haier: Compatible with compact 17-inch wide window units.
  • LG & Midea: Fits select 5k and 6k BTU mechanical and electronic units.
  • Note: Always measure the height, width, and depth of your AC's internal "face" before purchasing to ensure a proper seal.

When to Use This Cover

  • Winterization: Essential for preventing "through-the-unit" drafts that significantly increase heating bills in cold climates.
  • Off-Season Storage: Protects the internal chassis from household dust, pet hair, and cooking grease when the unit is not in use.
  • Noise Reduction: Provides a slight acoustic barrier against outside street noise and wind whistling through the vents.

Installation Tips

  • Clean the Unit First: Wipe down the AC face and vents with a damp cloth to remove dust before covering; this prevents mold from growing in trapped debris.
  • Power Cord Management: Thread the power cord through the designated Velcro gap at the bottom or side to ensure the cover sits flush against the wall or window frame.
  • Snug Fit: Pull the elastic edges over the corners first, then tighten the Velcro straps. A tight seal is critical—if the cover is loose, cold air will still circulate behind it.
  • Remove the Filter: Some users prefer to remove and clean the AC filter before covering the unit so it is ready for immediate use in the spring.

FAQ

This cover is designed for window air conditioner units that match the listed cover size of 17" x 13" x 3.5". For best results, measure the indoor-facing front of your window AC and compare those measurements to the cover size before ordering.
An indoor AC cover helps reduce drafts, dust intrusion, and heat loss that can come through a window air conditioner during colder months. The insulated polyester fiber fill layers add a barrier between the room and the exposed AC front.
This style installs over the interior-facing portion of the window air conditioner and uses Velcro side closures to help secure the fit around the unit. Installation is typically quick and usually takes just a few minutes with no tools required.
No. An indoor AC cover is typically used when the window air conditioner remains installed for the season. It fits over the inside portion of the unit to help block cold air and dust while the AC is not in use.
Before installing the cover, make sure the air conditioner is turned off, unplugged if accessible, and clean and dry. It's also a good idea to check the window seal and side panels for gaps, since the cover works best when the surrounding installation is already reasonably sealed.
It is not brand-specific. Fit depends mainly on the shape and dimensions of your indoor AC face rather than the manufacturer name. Measure your unit carefully, especially if it has protruding controls, a deep front grille, or an unusual cabinet shape.
You may need an indoor AC cover if you notice cold drafts around the air conditioner, increased dust buildup on the indoor grille during the off-season, or air leakage that makes the room harder to keep warm. If an older cover no longer stays in place or has lost its insulating thickness, replacing it can help restore better coverage.
