Probably one of the most versatile if not the most versatile portable evaporative AC today, the Soleus LX-140 14,000 BTU air conditioner is truly considered by experts as one of the most powerful and efficient models today.

It offers more than just comfort. Soleus offer innovation that resulted from years of their never ending research to make every day better than yesterday.

  1. It has a multifunctional design

Soleus Air LX-140, 14,000 BTU Evaporative Portable Air Conditioner, 14,200 BTU Heater, Dehumidifier and FanDeveloped by genius minds behind Soleus Air, this LX-140 AC can effectively and efficiently provide four functions (manual). Thus, eliminating the need to buy four separate devices and saving you time, energy, and money.

Because this device can deliver 14,000 BTU, it can efficiently cool rooms sized anywhere between 400 to 525 square feet. Come winter, you can still use this to provide warmth because it has a 14,200 BTU capacity. For those days when humidity is at its best making everyone feel uncomfortable, this can help remove up to 60 pints of excess moisture to keep everyone feeling refreshed despite the weather.

For those days when it is neither cold nor hot, one can resort to the fan-only mode which releases a simple, cool breeze to make sure there is fresh air circulating around the house. And for those nights when one cannot decide what temperature to choose, simply put it in auto mode and it will automatically select the appropriate temperature depending on the room’s current temperature.

The sleep mode is most especially helpful for those who wants to have comfortable cold air through the night but still wants to save money.

  1. This eliminates the need to empty water tanks

Boasting of an auto-evaporative technology, the Soleus LX-140 already includes a built-in 65-pint dehumidifier. The collected moisture is then recycled and eliminated through the exhaust duct.

But for those days when humidity is just too much, this device comes with an emergency holding tank with drainage port. This is located at the back of the device and is responsible for preventing potential water spillage to your delicate floors or expensive carpeting.

  1. It is energy efficient

The Soleus LX-140 portable evaporative air conditioner comes with a dual motor design. Because of this, one motor effectively cools the air while the other motor cools the condenser and compressor to make sure they will not overheat and efficiency of the device is maintained at all times.

In addition, there are non-corrosive aluminum fan blades that make sure that the collected condensation is distributed over the condenser. This ensures that the copper coils cool properly the way it should.


The Soleus LX-140 AC works great but there are customers who say that this is sometimes loud and would have been better if it was quiet throughout the time it is turned on. Customers who have had years of research and experience behind them know for a fact that the sound of this device is perfectly understandable given its mighty power.

Another thing though is that the hose could have been longer. What you can do here is anticipate this and get a hose extension kit in advance.
