DR.PREPARE 10,000 BTU Portable Air Conditioner with WiFi Enabled, Cooling, Dehumidifier, Fan & Sleep Modes 4-in-1 Portable AC w/Remote Control & 67'' Window Kit, Cools Up To 450 sq. ft, 1-24H Timers

The media could not be loaded. The product does what it promises. It blows cold air. The window kit works on my vertical window and will fill about 5 feet in length. Venting is done by a flexible hose much like a dryer vent hose. If I were to install this for the summer I would look into an insulated dryer hose as they will transfer less heat, and are made to handle moist hot air which is what this unit vents (for every action there is an opposite reaction -you have to make heat to make cold air.The item is about right with the square footage it can cool. Properly installed it will cool about 300 - 350sf of space. When it is 115 outside it struggles a bit, but so does a central air system. For me my kitchen is about 360sf and it helps keep it cool and dry. It does make a fair amount of noise as it is an AC unit with a compressor and heat exchanger. It uses an impeller type fan which should last. I find running the fan on low keeps the noise down to a reasonable level. But obviously the compressor makes that compressor sound no matter what.The unit is reasonably efficient only drawing 790 - 798 watts at maximum settings. So for a day's worth of use, assuming it ran all day without ever stopping, (which you should not do, it is made to cycle on and off at a set temp like 75), it would use about $2.15 for me. That may sound crazy, but my central air burns about $15 per day and it does cycle on and off. So in a proper environment, on a hot summer day, this unit may use $1 or so if it is cycling normally.The window kit is minimalist. it is made to fit windows up to just over 5 feet tall or wide. In my case I needed 5 feet worth. The smallest opening is about 27" but if you needed smaller you could cut the plastic down to size. As for the quality of sealing, you might want to use some sort of paint tape, or buy some foam stripping at a big box store -that would be ideal to get a good seal to keep heat out. It also depends on the window style as some may seal better than others.The controls make sense, I will be using the dehumidifier feature in winter for sure. Everything seems to work well. I did not use the phone app because it is just as easy to walk over and do what I need to do. I also like that it is using R32 for refrigerant. That's what the industry is moving to rapidly. General consensus is it is better than R410A, and more like R22 for cooling capability, And for the tech nerds, the Delta T is about 21 degrees on this unit, making it outperform my 3 ton R410A central air unit by 7 degrees. So it blows cold air for sure. The unit has a CEER rating of 6.3BTU/hr but using actual usage loads I come up with 8.3BTU/hr so I am not sure why the discrepancy (figid test environment maybe). I had AI check my math to be sure. 6.3 is okay, 8.3 is more okay. Don't pull the plug to shut off! Press the power button and let it go through its shutdown process of shutting off the compressor and letting the fan run to cool things down first.This is a very handy item to have in a time of need, or a hot room that needs some extra cooling, even to take the curse off a hot garage. I am wondering why I waited so long to be honest.

It’s noisy. Not so much that it’s disrupting to your sleep it’s just very noticeable. Additionally some of the control functions are a bit confusing. Like the sleep function, which turns on the AC once the room has increased in temperature and is meant to save you energy/help when you sleep. But frankly the temperature increases to a rather unpleasantly temperature with this function. The reason is because it won’t turn back on until the temperature has increased to about 6-8 degrees higher than it’s temp is set for. So if your used to sleeping at 74 degrees it’ll reach at least 80 before it will even consider turned back on, which seemingly makes the function pointless. And if you want the room to stay comfortable you have to set this to an uncomfortably low temperature so that it doesn’t increase to an uncomfortable high temperature in the room. Pointless. Aside from that there are only two speeds, high and “low” which feels and sounds like medium or rather not as high as high. SMH. I can’t complain too much. The price is reasonable. It cools a 10’x15’x10’ room fairly easily. And depending on the temperature you desire it can turn on quite often, especially when there’s someone generating body heat in the room with it, but it’s easily livable. The exhaust is simple to work with and fairly versatile. If you need a longer exhaust hose just get a 6” one and you’ll be set.

Had this for a week or so at this point and it works as expected. It keeps my office cool and dry at around 10-15 degrees cooler than outside. The installation was okay if a bit annoying to set up the exhaust hose. You get better with time on those. Noise is about what one would expect. I feel its like white noise so I'm not bothered by it but you'll need headphone if you're doing work. The remote is alright but unnecessary for daily use. Design is sleek and functional. Not sure about energy efficiency just yet as this month's power bill hasn't popped up yet.

Piece of junk, worked for 16 days, and then stopped blowing cold air. Don't want to give a refund. We'll never order from this company again.

This 14000btu Dr. Prepare portable a/c: installation went fine. The unit connected to wifi fine. I set a temperature of 62 deg F in the room to be used in, and a temperature setpoint of 90 deg F and it ran cooled for about an hour. Then the compressor cut off and only the fan ran even though it was not close to the temperature setpoint. I unplugged it and tried resetting the smart life app. I had intermittent success but the unit compressor would randomly turn off leaving the room to get hot due to it recirculating with just the fan. I need this to keep very important electrical equipment cool while I am away from home for several days. I cannot afford for the unit to just quit cooling while gone. I performed a loss of power check to make sure it would turn back on to its preset settings and it did, however, the compressor would not turn on even though the indicator showed 62 deg F of cooling on the faceplate. I am an ellectrical engineer of 42 years in the power industry. Also if the internet and/or wifi is lost, the unit cannot perform its cloud based functions. I need a unit that is not dependent on the cloud. I need it to cool whether internet/wifi is present or not. It needs to continue cooling with/without internet and/or wifi. purely on its local memory.

works very well

For a portable ac. I am impressed that it actually cools my whole house. And with the summer we have it’s been a great work horse woukd buy again. Also love that I can turn it in while I am at work so the house is cool by the time I get home

The AC cooled my living room down quickly. It’s lightweight, quiet, strong fan, easy to work with, and has nice wheels. However, it has a tiny bit of damage and is pretty cheap in quality. I would say it’s a tiny bit overpriced. May return.
