Great Product

This air conditioner was a little more expensive than some but worth the money. I turned a sweatbox into a great bedroom. Even on the hottest days it handled the temperature easily. Easy to manage and use.

Great little ac for bedroom

The unit itself is a little bulky and sticks out a fair bit but for a quality unit it’s worth it. I’ve seen cheaper unknown brands with smaller head units but I trust Daikin as being a good brand.

Cools Unit Well

Cools my 2 bedroom unit very well and also heats it satisfactorily but mainly only when on 25 degrees.
