Both of the my friends that have bought this brand were unsatisfied with their performance. They both had leaks in the system from the self installed lines and one of them ended up making a neighbor angry from the obnoxious noise the condenser made. Avoid ideal air is my motto.I work at a hydro store and we sell a good amount of Ideal Airs. I've only seen one customer have an issue with them.
Now it's certainly not the best type of unit but for the price, and the fact that you don't need a tech to install it, it's a pretty good buy. I'm really happy with mine.
