Single-hose units are a cost-cutting design and work more like a fan that blows cool air, only cooling the area directly in front of the unit. They create negative pressure indoors, drawing hot outdoor air in through door cracks and window gaps, making it feel like you're cooling with an open door or window. Dual-hose systems, with two separate air circulation pathways, are true air conditioners that can cool the entire room efficiently and are more energy-efficient.

In most cases, portable ACs do not require manual drainage. But if the humidity is over 85% RH and the room isn’t sealed, moisture from outside can 𝗰𝗼𝗻𝘁𝗶𝗻𝘂𝗼𝘂𝘀𝗹𝘆 𝗲𝗻𝘁𝗲𝗿, which may exceed the unit’s auto-evaporation capacity and require manual drainage. In such cases, unlike many portable ACs with drainage outlets at the bottom, our unit includes an additional drainage outlet positioned higher on the back, making the process much easier.

The cooling capacity of an air conditioner is influenced by the current temperature; the higher the temperature, the greater the challenge for the unit. ASHRAE 128 measures cooling capacity at 80°F, while SACC uses higher temperatures and stricter conditions, making it a more realistic measure of performance. Therefore, the SACC rating is usually lower but provides a more accurate assessment of the unit’s cooling efficiency in real-world conditions. Even for units rated at 14,000 BTU under ASHRAE 128, their SACC ratings can vary significantly. Since we don’t inflate the BTU rating of our unit, its size may be larger compared to some other "mini" models that falsely advertise 14,000 BTU. Its dimensions are 15.5" D x 17.7" W x 29.3" H.

The portable AC package includes two 20-inch window brackets and one 10-inch window bracket. If your window is larger, don’t worry. After receiving your portable AC, you can request additional window brackets for 𝗙𝗥𝗘𝗘.
