Question: what is the EER  rating?
Document: This worked great for my upstairs room in my home. It was averaging 95-100 all summer last year, and this unit held it steady at 72 all summer this year. 4 star rating because my electricity bill did go up more than I expected, but not too bad.
It is a little noisy, but not as noisy as some other units I have heard, and window AC units are naturally going to make noise.It definitely seems to be made with quality. I am very happy with the unit especially since it cooled a room twice the size of what its BTU rating was intended for. I highly recommend it.
This unit seems to get the job done. We haven't had a really hot summer so it hasn't been used a whole lot. It is keeping one half the house (about 700sq ft) comfortably cool. I like the energy saver feature. Waiting on my first electric bill. Still to early to give a five star rating...but it's close.
When I first read about this air conditioner, I was a little hesitant because I have never heard of SPT air conditioners. I decided to purchase it through amazon because of the over all high rating it had. This is the second year we have been using it and it is worth the money. It cools my 1100 square foot home to a comfortable temperature (which is way more square feet than it's recommended for).
If you're looking for an easy to install option, this is it. It is literally one box and the support for external parts. It is smaller than other units of the same rating. We had to make an adjustment to the whole in the wall as we did not install literally in a window. This made the job a little more cumbersome. I haven;t recv'd my first electricity bill, but if the info on the product is accurate, I should see a drop in my bill as well.
I ordered this model with some trepidation, having done quite a bit of research online to find a full featured, quiet model, and not finding what I wanted from better known brands like Fridigaire or LG at a reasonable price. I LOVE this AC. Compared to the Sharp it replaces, it's far quieter, especially on low. Its decibel rating is equivalent to the best rated consumer reports model, a Fridigaire. You can barely hear the compressor.
I have a 3 story giant 100 year old house. I don't feel like investing 3 grand in central air right now, so we still run 5 window units. Well this summer has been especially hot, so I researched buying another window A/C. This SPT WA-1211S is the ONLY A/C on Amazon with a 5 star rating, and there is a very good reason why. It is simply the best.
I attribute this to a lower construction quality (more on this below).The Panasonic had an EER of 10.0, while the SPT is 10.8, not really that much more efficient than a 14 year old AC!One problem we occasionally had with the Panasonic was that if it was used when the outside temperature was about 70 or below, the unit would ice up.
works like a champ that's all I can say it cools like a meat locker I love it great price to
while it might be a little louder than other units, i mean little, it works great. with a three fans placed at various spots, it cools my whole downstairs of four and a half rooms. not just cool, but well chilled at 72 to 74 degrees on a humid 93 degree day. glad i bought it.
Answer: 10.8
