Whynter - 400 Sq. Ft. Portable Air Conditioner - Silver

This AC has some minor downsides, but is overall excellent at its main job -- cooling. I purchased it after another AC (single-hose model with 10000 BTU, advertised for a 450 sq ft room) didn't cool my room properly. This one does the job with power to spare. Pros: 1) Powerful. (As far as portable ACs go. All portable ACs are less efficient than normal window ACs) 2) Quiet (as far as portable ACs go). While no portable AC is pleasant to be next to, this one is about as a fan. It's a little quieter than my previous, less powerful portable AC. The noise level doesn't change much when the compressor turns on or off. Cons (compared to that other AC): 1) Takes a little time (30 min) and effort to assemble. Needs a screwdriver for initial assembly and even to adjust the size of the window panel. Painful to detach hoses from the window panel unless you read the manual and know the trick (it's supposed to be twisted). I can see that for certain size of window, you'd need to cut the plastic panel for it to fit perfectly. My window was large enough that I didn't need to do this. 2) The UI and the remote are not great. The only way to see what temperature the room is currently at is to switch it to a fan mode. The display is hard to read, especially once the backlight turns off. The remote is supposed to show what the AC is set to, but its display easily gets out of sync with the actual setting.

I bought this to put in the master bedroom which is a little under 400 sq ft. This bedroom is west facing and heats up every evening as a result. It is also farthest from central AC unit and gets very low airflow. Our son's room is right next to central AC and I cannot equalize temps at night. Rather than freezing out our son, I got this to maintain a temperature in our bedroom. It is 3 feet away from the bed. I don't find the sound from it to be annoying at all. The compressor turning on and off my bother some people, but it is an AC, this is what they do. You can be hot with no AC or tolerate a compressor starting. If it bothers you they sell earplugs to help mitigate. I really like the dual hose design but I had to use the continuous drain option for the water. I created my own hose connection that drains into a bucket since it is humid where we live. For our purpose, this works great.

After researching online, including reviews in Consumer Reports, decided on this unit. After shopping around, Amazon had the best price, but anyone who's ever done business with Best Buy knows that when it comes to the overall promise of making the customer happy, only Costco is in the same ballpark. After getting on the phone to make the order, Best Buy matched Amazon's price. Nuff said. The only "shortcoming" is that the window adapter wouldn't work in any of my windows and especially the window where I chose to install it. I'm DIYer, so fabricating a window adapter using scraps that I had around was not a big deal. The other thing to be aware of is that it is recommended that you put these units on one circuit by itself. I originally had it on a circuit that shared a computer, some lights, and a TV. The plugs got hot to the touch. It was probably still safe, but not wanting to take a chance, I ran an extension cord from an outside plug that had nothing else on it. Problem solved.

I bought this almost two years ago. The good: It cools well. The bad: it was fine for a year then started making the dreaded ca-CHUNK each time the compressor turns off. It wakes us up at night now. Made it through half a season(2020) and whole season last year with no problems. It didn't get moved or damaged. The other thing is started doing is an incessant buzzing in the plastic case when the compressor was running. Tried everything to get it to stop. Note: I sent an email to the company for direction on both issues and got no response. It's out of warranty now so i guess they don't care. We went out and bought a window unit that is WAAAAY more quiet. Not sure what to do with this now.

I've been using this for almost a month now and it has been great! Cools down a 400ish Sq. ft. Living room in under an hour with no problem. It's quiet and has an easy interface. Be sure to not turn it on right away, let it sit for at least four hours after setting up (it explains this in the manual). I let it sit a whole night before first use and it's worked perfect.

I took a chance on this unit, based off of the reviews…I regret it. I had issues almost right away, after getting it installed and using it a handful of times. It would shut itself off completely at random, and when I reached out to customer service (Best Buy said that since it was within the year warranty, I had to go through the manufacturer). I got the basic troubleshooting guide (is it plugged in, does the wall outlet work, etc.), as well as being told that the unit shuts off once it gets within 5° of the set temperature, and will turn back on after 15 minutes…it didn’t, I would have to turn it back on manually. Then, I started having issues with it sounding like the fan was hitting or rubbing. I again reached out to the manufacturer and received more troubleshooting guides, as well as being told that I needed to open the back of the unit myself, and make sure that there wasn’t any damage. They told me they would have to send a service tech out, and I asked them if we could have someone out ASAP, as the weather is starting to get hot. Nothing has been scheduled, and no reply in the last few days, other than asking me to provide my order invoice for the 3rd time. I ended up taking the unit back to Best Buy tonight and getting a new, cheaper unit, at the cost of $144 out of my own pocket because of Whynter’s abysmal customer support and losing my Geek Squad warranty on it. I will never purchase another one of their products.

Wish it got colder faster, but it does the job. We live in Cali where it’s dry, so never really had to empty the drip pan. It’s in storage for the winter months and hopefully it holds up well.

This works great in my bedroom. Bought for my home office but it moved to my bedroom due to it being quieter than my 5 yr old Honeywell portable air conditioner. Actually I wanted to buy this brand 5 years ago but Best Buy was out of them. Only difficult part was removing the covers the had covering the exterior vent that goes in the window.

We needed A/C on the second floor of an 80 year old brick house with steel encasement windows. This unit was researched by a Boing engineer family member which he thought was the best available for our needs. Best Buy had the best price. This unit is quiet and efficient.
