Its flexible zipper design lets you position the exhaust hose at any height, eliminating alignment issues common with fixed couplers. The no-drill installation protects your window frame while improving cooling efficiency by sealing out hot air and keeping cold air inside. Ideal for high-capacity AC units up to 12,000 BTU, this waterproof vent kit saves energy and lowers electricity costs.
Loviga Adjustable Portable Air Conditioner Window Kit
The Loviga Portable Air Conditioner Window Kit is an adjustable seal designed to fit horizontal and vertical sliding windows, ranging in length from 40 to 64 inches. Unlike zipper designs, this kit uses a drawstring system to create a tight and durable seal around exhaust hoses sized 1 to 6 inches in diameter. Its waterproof TU fabric reflects sunlight and provides heat insulation, preventing outdoor warmth from entering and maintaining energy savings. Enhanced with double-stitched threads and wide Velcro tape, Loviga’s vent kit simplifies installation and improves reliability.

It is highly portable with wheels, but to maximize its efficiency with vertical crank windows, pairing this AC with a compatible window seal kit is recommended to prevent hot air intrusion.
Buying Guide: Choosing the Right Air Conditioner and Seal Kit for Vertical Crank Windows
When selecting an air conditioner and window seal kit for vertical crank windows, consider the following aspects to ensure optimal performance and comfort:
Window Compatibility
- Seal Kit Fit: Vertical crank and casement windows require window seal kits explicitly designed for non-sliding windows with inward or outward opening panes. Check the perimeter length and hose compatibility.
- AC Unit Dimensions: Ensure the AC fits your window opening, especially for compact window air conditioners or portable units requiring proper venting.
Seal and Insulation Quality
- Material Durability: Look for waterproof and heat-resistant fabrics such as nylon or PU-coated materials that withstand weather exposure.
- Closure Type: Zippered seals provide convenient hose access, but drawstring designs may offer tighter, more durable sealing without gaps.
- Energy Efficiency: Effective sealing prevents hot air return and cold air loss, which reduces the operating load on your AC and lowers electricity consumption.
Cooling Capacity and Room Size
- BTU Rating: Match the BTU capacity of the air conditioner to your room size (e.g., 5,000 BTU for small rooms, ~10,000 BTU for mid-size rooms).
- Multi-function Units: Portable AC units with dehumidifier and fan modes can improve overall indoor comfort.
Installation and Maintenance
- Ease of Installation: Non-drill, zippered window seals typically simplify setup and removal.
- Adjustability: Adjustable-length kits offer better adaptability for varying window sizes and exhaust hose diameters.
- Maintenance: Choose washable or easy-to-clean materials to maintain hygiene and performance.
Additional Features
- Noise Levels: Consider low-noise AC units for bedroom or office use.
- Portability: Wheeled units allow flexible room placement but must include compatible venting solutions.
- Environmental Impact: Efficient seals help reduce energy consumption and carbon footprint.
Carefully matching your air conditioner with a high-quality window seal kit designed for vertical crank windows will maximize cooling efficiency and energy savings while improving indoor comfort during warm months.
