Question: Is this unit BOLTED in some way to the window?  Would it be easy to take out for the winter and put back in the summer?  Thanks!
Document: The damaged cooling fins should not result in much loss of efficiency, but the ugly scar is irritating on a "new" appliance. So you can take your chance on getting a good one, but be prepared to send it back for replacement. Amazon does make that fairly painless.With better packaging, I would rate this model 4-star or 5-star.
I have a 15x15 room and I live in NJ, This unit barely  cools my room and the temps have not been above 83 (its not even summer). It is quiet...but quietly ineffective. I saw great reviews on this item and purchased even though it was expensive($279) for the BTU flow, however I thought it would be easy to buy online with free shipping and the reviews raved about the quietness.
Replaced outdated window unit upon advise of friend. Boy was he right this unit is fantastic.Is much more efficient in every way. Easy to install
I bought this several weeks ago and just installed it with the coming of our first heat wave. I bought this specifically because it directs the air up rather than out. All the other room air conditioners I had, or looked at, blew the air onto the back of my neck, which annoyed me no end. For this reason alone, the extra price on this unit is well worth paying. An added bonus is the low profile, allowing me to still see out of the window.Installation was easy.
But I found some heavy wire ties and strapped it back down. Likely the new design is better. It's so quiet that I just couldn't stand to replace it. It has a handle on it like a suitcase and is easy to lug upstairs. It has this flimsy little plastic dust screen to clean that you'd never suspect would be in perfect shape after 18 years. High praises to Frigidair!
Looks good. Works good. would have been easy to install with sliders but we have awning windows...quite a project. But it is a nice air conditioner than cools one room a good 10 degrees down from the 90's of the high desert. Wish there was some way of really communicating the sound level. Other reviews said quiet -which is important. I think it is &#34;not noisy&#34;, but my mom thinks it IS noisy!
This was the first of two AC window units I bought this summer.The good:1. It is indeed low-profile.2. It is super easy to install and is quite secure in my window.3. It is relatively quiet.4. There is plenty of insulation provided with the unit, so you can really seal things up.5. It doesn't use a ton of power.
I purchased this low-profile unit based on two criteria: quietness and size. I wanted a quiet unit that didn't look obtrusive in the room. It scores an "A" on both counts. It wasn't difficult to install, which is a plus, and it cools the room very nicely. We have a small house, so it also cools a couple of other rooms. Before next summer we will purchase the same model to put at the other side of the house.
So I bought this unit to keep just my room nice and cool It does a great job. Even use it during the winter months when I just want to get some fresh air to circulate through my bedroom. I do wish they would come up with some breakthroughs to make these units quieter, but that's my only recommendation.
We needed to replace a very noisy window unit. This unit is amazingly quiet!! Easy to install. Very happy with this purchase and would recommend this A/c unit without hesitation!! !
Answer: You can easily take this out for the winter and put it back in the summer. Mine has been in a closet since fall and will be taken out again in the next few days to enjoy another cool summer. There is a flange that is secured to the sill, and the unit rests on that flange. It' a wonderful unit ... it kept me cool all summer last year.
