Summary: What a piece of garbage. This is less an air conditioner, and more of a movie prop of what an air conditioner would look like. In fact, I would not dignify it by calling it an air conditioner -- just a Thing. Our contractor bought us these Things. I had a feeling he was angry at us, but now I know. Of the three we have 1 sorta blows air, 1 sorta doesn't and the other doesn't even turn on. GARBAGE. Do the people at TechniTrend have any shame?
Summary: Look, I'm not going to go ahead and say that this is the BEST portable A/C unit on the planet... But I will say it's pretty good for the price. It does a pretty good job of cooling a medium sized room and greatly aids personal comfort. A couple things you should know about this unit are that it is fairly loud (though the white noise helps me sleep) and it does need maintenance. Make sure you clean the air filter and drain the water AT LEAST once a year.
Summary: I bought this product about 3 years ago brand new and have used it for about 2 weeks every year since then. It is not at all effective in cooling any room. I've used it on a room that's maybe 500 sq ft max. After running for about 2 hours, it manages to cool the room temp from 90(f) to about 84(f). I'd expect a lot more from a nearly $400 and 12000 BTU unit.
Summary: We got this unit used from friends who bought it when their main A/C quit in the heat of summer (near Livermore, CA). We got it for use at our modest cabin in the Sierra Nevada near Arnold, CA last year, and it has performed flawlessly. Installation went easily and well, but presented a problem. While we were gone, rodents chewed through the nylon screen and through the foam baffle and entered the house.
Summary: I was so excited to get this unit, we needed it to cool a regular sized bedroom (10x12) on hot days because the windows weren't shaped for a window unit. The cost was steep but we bit the bullet thinking it would be worth it to sleep in a cool room in the summer. We were so wrong. First of all, it is enormous and loud. The hose and window installation kit is flimsy at best and never stays in place, we had to build our own kit.
Summary: I've had this A/C for 2 years now and I LOVE IT. We use it during the summers to cool our large master bedroom which is very poorly insulated and has a huge window that faces west. We actually have two units which we use when temperatures are in the upper 90's to low 100's, one in each side of the large 3-paned sliding window.
Summary: The other reviewer, Alesia, summed up my experiences to a tee (i.e., abysmal). All I will add is that it does not cool worth a darn. I live in Vancouver, BC - not exactly the AZ desert, and it couldn't cool a small with the outside temperature at 85 F if its life depended on it. And it did...trashed it last week.
