Description of the KSTAP14B

In case you are looking for a strong air conditioner for your large space, then you should consider the KSTAP14B. This powerful air conditioner offers a cooling capacity of 14,000 BTU. Its impressive cooling capacity makes it a suitable choice for rooms that are as large as 700 square feet. In addition, this AC is highly effective and cools a room within a short time.

If you want to control the temperature and the relative humidity of your room, then you need a multipurpose air conditioner instead of buying two separate appliances. This air conditioner features a built-in dehumidifier that is capable of pulling up to 72 pints of moisture from the air per day.

This dehumidifier pulls excess moisture to ensure that your room is unsuitable for the growth of mold and mildew. It also helps to protect your possessions from the damaging effects of excess moisture.

Unlike most dehumidifiers, this air conditioner employs a self-evaporative mechanism and does not feature a bucket. Emptying the bucket manually is a boring task that demands regular user attention. This unit is different and therefore suitable for people who don’t have time for such tasks. In addition, this design ensures that the system runs continuously without warnings or shut offs.

The KSTAP14B features a remote control that allows you to adjust the environment of your room without the need to walk to where the unit is positioned. In addition, it features an LCD remote control and offers a 24-hr timer.

Furthermore, the KSTAP14B features caster wheels that allow you to move it from one position to another by pushing it.
From our research, we have noted that the KSTAP14B has a poorly designed exhaust hose that make it difficult for users to install it with ease.

In addition, this inflexible hose is poorly insulated and allows heat back into the room. To enhance the efficiency, you can wrap it with a good insulator.

  • Effective cooling. We have observed that this unit cools a large room within a short time. It performs well in rooms that are as large as 700 square feet.
  • Strong dehumidifier. The built-in dehumidifier of this portable air conditioner is capable of pulling a lot of moisture from the air within a short time.
  • No bucket to empty. The unit uses self-evaporative mechanism and therefore does not require regular user attention.


  • The fan produces noise. We have observed that this unit produces a disturbing sound. In case you are intending to use your air conditioner in a quiet room, then you may need to consider another unit.
  • The exhaust hose is poorly designed. The hose is not flexible and it is hard to attach it with the available fittings.
  • Poor insulation lowers efficiency. The exhaust hose and the window sealing are not properly insulated. This allows some heat to escape back to the room thereby lowering the overall efficiency.
  • Leaks water. We have noted that many cases of the unit leaking water have been reported.

Users’ feedback

Users quotes on Amazon.comI got this AC this week for the great heat wave of 2015 in San Diego. It has saved us! All necessary accessories (including foam stripping) is included. Easy hookup through my window. Turned right on and cooled the entire downstairs within 1 hour. 2 large rooms…not sure of sq footage. Easy instructions. It helps to have had a portable unit (not same brand) and know what to expect. They are never as great as central air, but should make a significant difference in the footage allotted for in the description. I have a house built in 1923. This works for me.”

Users quotes on Amazon.comItem showed up in a timely manner. Using the unit for AC in a room that is a little larger than what it is rated for but keeps it comfortable. Maintains a 15 degree difference between outside and inside temperature. Room size is about 1,000 sq.ft. that I am trying to cool. Fan is a little noisy, just positioned the unit away from our normal seating area. Overall happy with the unit and staying comfortable. Only added a $1 per day to run, well worth staying cool.”
