Cools our bedroom and then some. About as noisy as having a fan on at night so that was a plus. The vent hose system is a little cheap but duct tape took care of that. Very pleased with it.

I love this Air Conditioner. We moved into a new apartment in an area that gets very warm in the summer and fall. It has an wall mounted, personal a/c unit in the living room but it does not reach our bedroom. This product is nearly perfect! It cools the room quickly, isnt loud at all and doesnt take forever to clean/maintain it.

It's a great A.C. unit that's well made and cools quickly. It's a little bigger and heavier than what I originally thought, and the air intake hose requires more room. But this also means that it's a robust piece of hardware. Also the window bar comes with an extension so it could be fit vertically or horizontally. Overall highly recommended. I wish I bought one sooner.

This AC isn't quite as powerful as my previous unit but it's much quieter. The auto-evap system appears to work very well. Every time I check the drain ports on the back it appears to be empty. I use this in the bedroom to keep it cool at night. It takes awhile to cool the room so I usually turn it on a half hour before I turn in. I wish you could direct the fan blades. I use a box fan to help circulate the cool air where I want it. Works very well in my case but I wouldn't recommend it for a large room. Installation was mostly easy but I had to carve through one of the window kit sections in order to make it fit.

Thanks for the review! We're happy to hear that you're satisfied with the overall performance of our Honeywell Portable Air Conditioner. We appreciate you sharing your thoughts on the design of the window kit and air outlet, and we'd be happy to note that for product improvement purposes. The HL10 is recommended for a 350 sq ft room so it should not be expected to cool a large room. However, we'd love to recommend a more powerful Portable AC unit that'll work great for your specific needs. Please feel free to give us a call at 1-800-474-2147 between 8:30 am and 5:30 pm EST Monday through Friday or send us an email at [email protected]. Thanks again!

The unit works well and definitely cools and dehumidifies.
The instructions are easy to understand.
We ordered this because it was made in the US and used relatively lower power compared to other models.
So that part is very good.
The one feature that is not up to the others is the window mounting. Ideally it would be a little taller with more room to reach further down to the sill at the bottom so you don't have to bend the hose to the window as much to get around the sill.
Also the expansion bar requires you cut it for all but the widest windows. This part of the system could really have taken a bit more care in the design, but I do see similar issues with folks who bought other brands instead.
Otherwise for cooling and electrical usage it does GREAT!
So I give it a 4.4 out of 5.

Thank you for your review! We're happy to hear you're satisfied with the performance of our Honeywell Portable Air Conditioner, and we appreciate you taking the time to share your experience with us. The window venting kit that comes with the unit measures 26.6 inches. It can then be extended from 36.2 to 52 inches. If the size of your windows is not within these measurements, then the bracket will need to be modified. Please feel free to get in touch with us at [email protected] for any support or assistance.

My mother has not had the luxury of owning an air conditioner for several years. I purchased this unit to help cool down her living room and increase her comfort level during the recent heat wave in So Cal. This was a welcome relief. Surprisingly, it's not too loud and is effective and requires minimal maintenance.

Combats global warming...one room at a time! Surprisingly cold output quickly cools down a moderate sized room. Cuts back on electricity bills if you don’t need central ac to cool down an entire house. Definitely need to exhaust the hot air outside with the supplied hardware and keep an eye on the water that doesn’t get automatically evaporated.

This Honeywell - 450 Sq. Ft. Portable Air Conditioner has worked well for us for years now. It seems that Honeywell is a long time well designed product and worth trusting. Just plan ahead to be sure you can place it close enough to a window for the exhaust tube. It's helpful that it can be wheeled.

Bought this to us in our bedroom and office and works great on hot days. Really worth the price and easy to set up. If you have abnormal window lengths, you will need to buy some material to help cover the open area, but otherwise, a great product.

I purchased this to replace an older 8000 BTU unit and it is much much better. It now adequately cools the entire room and it's even quiet enough to leave on overnight.

This portable AC has saved my life this summer! One of the hottest in Colorado history, upper 90s every day! Too hot. But with this neat AC I am able to sleep comfortably. Worth every penny. Delivered right to my door, no delivery charge. I was able to get it running all by myself!

The only reason for marking this unit down is the weight. Other than being heavy, it’s a great AC unit. It works quick and is very quiet compared to other units.

Thank you for your review! We're happy to hear you're satisfied with the performance of our Honeywell Portable Air Conditioner, and we appreciate you taking the time to share your experience with us. These units tend to be heavy due to the powerful compressors that these come with. Our portable air conditioners make use of dual motor technology, making them quieter than most others in the market.

This pretty much has all the settings you would want from an a/c. Super easy to set up and the remote makes it extremely easy to adjust to your liking. Keeps a little over 500sq ft nice and cool instead of just one direct spot.
