Best Portable Air Conditioner

Are you looking to vamp up your room space? Well, look no further. Portable air conditioners are the most efficient ways that will help you in maintaining a cool temperature inside, without any hassle of dealing with long power cords or noisy machines.

The portable AC units are more convenient since they are light in weight and easily installable without much effort. Besides cooling your rooms efficiently they also remove excess humidity from indoor spaces helping in improving humidity levels inside rooms.

Most of the newer models come with advanced features like auto restart, self-evaporating system, dehumidifier function, etc which makes them very efficient at work even while being on for longer hours than traditional window ACs.  They use eco-friendly refrigerants which are not hazardous to your health. They are more energy-efficient too.

The difference between window and portable air conditioners is in their installation. While window air conditions are fixed in one window, the portable ACs can be moved from one place to another as required. They come with a hose and an exhaust hose, which helps in ventilating hot indoor air outside and releasing it through the exhaust hose.

Portable ACs are very useful for cooling your bedroom, office, or any other large room where there is no central cooling system installed. It is also more energy-efficient than window units.

In order to choose the best air conditioner, you must first have a clear idea of what size of AC will suit your room space. Always go for a unit that has a higher BTU rating compared to the space you want to be cooled down.

Love it! Worth every penny. I personally don’t find it very loud. I use it as both a fan and air conditioner. The window kit worked great and I haven’t had a problem. It was a bit short for my vertical window and I just patched up the remaining opening myself. Didn’t want to pay for the extension kit. My blinds cover it anyway so it can’t be seen. It cools my approximately 700-750 square feet main level just fine. No it doesn’t make it “cold”, it makes it a comfortable temperature…
