  1. De’Longhi Portable Air Conditioner for Slider Windows

This De’Longhi Portable Air conditioner is a great portable cooling option because it is efficient and has options that allow you to raise or lower your thermostat as you please while conserving energy.

This unit is different from window units, because it is a neatly constructed stand alone in the house that can be easily moved from room to room.

Mobility is made possible by the four castors on the bottom of the unit. If you have a vertical or horizontal window, setup is pretty easy. That ease is largely facilitated by the full window kit which is included with the purchase of this unit.

The De’Longhi has different modes that include cooling mode, fan only mode and dehumidifying mode which all add to your comfort and helps meet different cooling needs in a given day.

Customer feedback

A customer who installed this in his kitchens remarked that it cools far more than it’s rated for and the large caster wheels make it easier to move the unit around. Beyond efficiency, the unit has a smaller exhaust diameter than most and therefore takes less space.


You may already have an existing centralized AC unit in your home but need to save on the energy during the day or night with rooms that are not being used.

One of the best ways to do that is using a Portable Air Conditioner that is easy to setup on vertical or horizontal sliding windows, and delivers on cooling. It can be put in storage with ease until needed again. All the above options open up a whole world of affordable cooling for your home, office, or cabin.
