Uthfy HY-40BI-51 swamp cooler, navy blue

WOW! Excellent way to take the edge off the heat, making spring and summer gardening a pleasant endeavor and not an unbearable chore! Yes, I recommend getting this... way worth the investment. Powerful fan puts out a lot of cooler air and keeps the area very comfortable. A little loud if using in the garage. This is our 2nd summer with the unit. We can rely on its dependability... it works just as good as it did last year. Thank you.

This Swamp Cooler is doing a great job on my back patio right now. It's 88 degrees outside here in Phoenix AZ and the swamp (or evaporative cooler) with the water running is keeping the patio right around 72/73 degrees. A long time ago, I lived in an old house here in Phoenix that only had a swamp cooler, and that unit had four sides, with each side having a wet pad to keep the house cool. So, when selecting an outdoor cooler I wanted be sure all sides pulling in hot air would have a wet pad that would cool all the air coming into the unit. Some of other cooler I looked at only had one pad in the back, with two sides vents that would pull in hot air, which in the end would make the cold air from the wet pad in the back warmer before it reached the motor that pushed the air out me - I'm so glad I found this unit! This unit looks to be well made, is sturdy, and rolls very easy even when filled with water. The motor is so strong that I don't even need to put it on high to cool off my 9x15 patio, the lowest setting works fine for me for now. Plus, the ice blocks have stayed frozen/cold all afternoon in the water, maybe 5 hours now and the water is still very cold. I used my new ECOFLOW solar power station to get an idea of the watts used by this swamp cooler .... Using the unit with the fan on low it pulled around 92w - on high it pulled around 164w. Using the swamp cooler on low with water pump running it pulled around 119w - on high it pulled around 187w. Now, the down side ... I'm having a problem with the hose connection leaking. I used some Plummer's tape to avoid this problem, but the connection site leaked anyway. I tried tightening the connection as much as I dared, as I'm afraid if I over-tighten it will destroy plastic plug connection in the unit's wall. This isn't a deal breaker for me as it is a very small leak and I just put a cup under to catch the dripping water, but it would be nice if I could get it to stop dripping. Maybe the seller will see this comment and help me figure out why the connection has a problem. Update 05/09/25 -- Wanted to add that their customer service is excellent! I needed some help with the swamp cooler and had some questions, and I found this company to be very considerate, understanding, and helpful to my needs. Also, right now it's exactly 100 degrees here in Phoenix AZ without the cooler, after turning on my new cooler the thermostat is now reading 83.5 degrees - AWESOME - and, it is still on the low setting. I'm over the moon with this company, customer service, and of course the swamp cooler. Thank you so much!

This swamp cooler works well and keeps my garage cool when I want to work there. I like the ability to switch the oscillating grill off and on. If you want to focus on working at your workbench or sit in a chair, turn the oscillation off. The push button and toggle switch controls make it easy to adjust fan speed, cooling and oscillation. The unit is on four castors which makes moving the unit easy. The top of the unit has a lid which provides access to the upper water reservoir and you can add frozen, plastic, blue freezer containers to cool the air more. The cons about this cooler are: 1) the connection pipe is poorly mounted on the cooler. It took a long time to figure out how to attach a hose and shutoff without leakage where the connection enters the cooler. It’s cheaply made and I was afraid it would break. 2) the water level indicator is a plastic float which continuously sticks in the tube it’s in. You have to open the access flap to feel what the water level is. 3) cleaning isn’t very easy. I kept this unit because it works well and is problematic returning. I’ve had it for a year and it’s still working and not leaking.

Very impressed with this portable AC. Powerful cooling, compact and easy to move around. Setup took me less than 10 minutes. Runs smoothly and works great for my home office and bedroom. Remote works well and the dehumidifier function is a nice bonus. Worth every penny, would buy again.

Works like stated. Straightforward design. Seems quality built, though caster wheels could be a bit larger to aid maneuvering on concrete or at poolside
