Top 5 Best Energy Efficient Window AC Units for Superior Performance

“Well I feel like I robbed someone. Bought the Used Like New for under $100. It arrived in original packaging and didn’t look like it was ever open. Its really cold right now but I put it in one of my warm rooms. Turned it on. In a few minutes the compressor kicked on and it was blowing ice cold air. If you can grab a used like new do it. I actually bought a second one as I couldn’t pass up the deal!We will see how long it lasts but I can say it came in great condition and worked as it should.”

“It takes a little getting used to because it seems to reset to the ‘auto’ position after it’s been turned off, and I like the fan on high even though that’s a little noisy. Quality of the machine overall is good. The ECO setting is perfect – both the fan and compressor shut off when the temp is reached (as opposed to most window units that the fan stays in all the time and just the compressor kicks off ). It fits a single window well, though the self stick weather stripping did not stay stuck. I wound up caulking around it and figured it would be easy enough to clean off when we remove it for the winter.The buttons are hard to read, mainly because my windows are low, but I took a picture of the control panel so I can blow it up on my phone and determine what light is actually lit. I think the writing on the label could be a bit darker and the LED lights could be a bit brighter. (I swear, I’m not going blind!)Overall, it’s definitely worth the money I spent. Not sure if they recommend a dedicated circuit, but I think that should be the case. It draws quite a bit of power when the compressor kicks in.”

“I was on the fence about getting this because we have central air and heat. The house we bought a couple years ago has a brand new one put in after we purchased the house. BUT, our primary bedroom is the last room to get air, so our bedroom is always 10-20 degrees hotter than the rest of our home. We also live in Texas, so our summers are super hot and humid. I’m so glad I purchased this! It makes our bedroom perfect now. It’s nice and cold now like the rest of the house. I hate the way window units look normally, but this one isn’t bad at all. I actually like the small size. It’s small enough to just close the curtains in the winter/fall and you won’t even know it’s there. Thankfully, our bedroom windows face the backyard, so the neighbors don’t have to ever look at it. It was also affordable. I’ll have to get better pictures of it soon.”

“Easy to set up. Works great! noise level is fine. Kept the room cool in hot summer days!”

“Can’t stand this window unit, it only stays on for 4 hours then it turns itself off & stays off for five hours before it comes back on, I now wished I had not purchased this. The only thing good about it, is it is very quiet”

“Works very well, eco mode is saving us a lot of power, in the cool fall nights it simply just shuts down when not needed”

“Despite the fact due to room size I should have bought a 10-12,000 BTU and this is only a 6,000, this air conditioner works extremely well. Mind your room size especially if you have high ceilings. I would always go with the higher BTU. When it was in the mid 90s farenheit with high humidity it had a bit of difficulty keeping the 20×17 room icy cold. It has cooled the room beautifully most of the time, however, with very little noise. I leave it on 24-7. Also very energy efficient. Highly recommend.”

“No problems! Cools bedroom, is quiet, remote works well, well worth the price. Would buy again!”

“Works great so far. We’ve had it for several months. It does leak a TON of condensation (in very humid South Texas), so you’ll need something under it outside. We just put a plant pot, and that looks/works fine. As for cooling, it makes our living area cold when it’s 90°+ outside, so I’d say it works. It’s not going to cool a whole house though. We have one in the living area, one in a bedroom, and we need one in another bedroom at the other end of the house. Three would keep a 3 bed house cold.”

“I bought this for my garage. I live in Alabama. It is March 7, 2023 and was 86 degrees today. This air conditioner was delivered today, so you know I had to install it! Packaging was easy to remove. Now, I must have the world’s smallest window in my garage. It’s an old, metal frame window. When I read the description, it seemed like it would fit perfectly after measuring my window. The unit itself fit no problem. The issue was the side panels. It was just like an inch too big horizontally to fit my window. However, I remedied this issue by cutting an inch off of the left and right panel frames. Doing this allowed it to fit perfectly. The height was fine. The screws it comes with are kind of junk, but they work for what you need. Also, the mounting brackets didnt work for me, but again, I have some crazy windowns, apparently. So I made my modifications, installed it, and turned it on. Initially, it made a lot of noise kicking on the first time. Now it’s quite quiet. It’s blowing out some seriously cold air. I am in the process of insulating my garage (already did the garage doors, working on throwing up the panels on the rafters). I think this is going make working on my cars during the summer exponentially better. I don’t know how it will do in the full blown summer yet, but I have high hopes. It will at least be tolerable. I’ll update in a few months if anything goes wrong with it. Side note: if you want to insulate your garage with insulation panels, go to Lowes over home depot. I got Poly Pro 3/4″ thick 4′ x 8′ panels for approx. $15 a piece. Just use a sharp utility knife to cut it and gorilla glue hot glue sticks to mount it to your garage door panels (you’ll need to put blocks of the insulation panels on the garage doors before you install your cut panels or else the height won’t be right. You’ll know what I’m talking about if you go to do it.) Thank me later.”
