Kewling's evaporative air coolers and fans are built for personal comfort and lower energy use. This lineup is different: four products built around a real refrigerant compressor, for when you need to actually bring a room's temperature down rather than just move air around. Here's how the four pieces fit together.
1. 9,000 BTU Single-Hose Smart Portable Air Conditioner — $750
The single-room workhorse. Best for a bedroom, home office, nursery, or studio apartment up to roughly 350–400 sq ft. Single-hose venting, heating mode included.
2. 12,000 BTU Dual-Hose Wi-Fi Portable Air Conditioner — $750
The step up for larger or leakier spaces — living rooms, garages, open-plan areas. Dual-hose venting cools faster because it never pulls its condenser air from inside the room. Adds a DC inverter compressor, heat pump heating, auto-swing vent, temperature-sensing remote, built-in UVC purification, and Wi-Fi.
3. Compact Compressor Mini Air Conditioner — from $550
A true compressor AC scaled down for tents, camper vans, and desks — not an evaporative fan wearing an AC label. Available in 8, 9, or 10 m² usable-area sizes.
4. Universal Portable AC Window Seal Kit — from $45
The accessory that makes the other three actually perform to spec. A reusable, no-drill panel with a single adjustable zipper track — one opening for single-hose units, two stacked openings for dual-hose units. Available in 3M–6M sizes.

FAQ
What's the difference between these and Kewling's air coolers?
These four products use a refrigerant compressor to actually remove heat from a room, the same core technology as a home AC unit. Kewling's air coolers use water evaporation instead — lower energy use, but weaker and more humidity-dependent cooling.
Do I need the window seal kit if my unit comes with a hose?
Yes. The hose vents hot air out, but without a proper seal around it, warm outside air leaks back in and cooled air leaks out — cutting into real-world performance.
Can I buy the trade discount if I need multiple units for a property?
Yes — see Kewling's Trade Program for volume pricing on bulk orders.
Which unit ships fastest for a heatwave this week?
All four are in stock and ship immediately — check the product page for current inventory before ordering.
