Whynter ARC-148MHP 14,000 BTU Portable Air Conditioner and 10,000 BTU Portable Air Heater with Dehumidifier and Fan for 500 Square Foot Rooms, White

I purchased one of these Dec 22, 2015 and paid $638.59!! It still runs perfect to this day. I used it it to cool my master bedroom and various rooms in my home during construction and the AC unit had to be removed. Ity saved our lives and sleep and basic comfort. I used it many times when the carpet was cleaned to remove the water and humidity from the air which helped the carpets dry significantly faster. I have a home office that in the difficult months of summer, that room gets baked and is 20 degrees hotter than the balance of the home. This thing is a life saver. Never a single problem ever and its been in seasonal use, mostly, for almost a decade now! It has been a very reliable.I purchased a 2nd unit for my Father in Law as a gift because has no central cooling and there have been extremely hot and humid weather. He would never have purchased himself so we got it for him in August 2016 (price was $499 then). It also has been running reliably since then and it is the ONLY AC he has. It has been a life saver for a Senior Citizen running every summer and during any high humidity times due to storms on the coast in San Diego CA just north of the border. Highly recommend this unit.

UPS driver brought it upstairs. It as easy to set up. The vent tube is amazing! I let it sit unused for 24 hours, so the working fluid would settle. The plug has a button for reset, when pressed, it works. I plugged it into my Ecoflow power station Delta 2000, with solar panel in the window, and the heat pump works fine. It has a nice fan which make a pleasant breeze in the room, cool which cools the temp, heat which heats the temp, and the temp is easy to set. It uses about 1400 watts to work. I don't like the dehumidify, because it cools the air too cold, without me being able to limit it. Now the vent tube is a little tricky so here is my advice. I failed to use the little plastic screw to fasten the two panels of the window covering; I used a metal screw; but it worked. The foam insulation doesn't wrap around the edge of the window covering real well, so you might want to order some foam with a strong adhesive about three or four inches wide, and long enough to all sides of the window panel. Moreover, my bedroom is now wonderful, so much nicer, cool, warm, just right. I love the heat pump. It cost less than some purses you could have bought instead, but it's another example of Chinese expertise in design and manufacture. A big hug to the Chinese people.

I don't usually write reviews, let alone one this detailed, but since this is a high ticket item, I figured I'd put in the review. Hopefully it helps someone else make their decision. To briefly summarize the review below up-front for those that don't want to read it: yes, so far, i recommend this machine.I did a LOT of homework before settling on this unit. This is not my first portable AC unit, so I'm really really picky about the one i did get based on past experience. I don't live on a ground floor, and hauling this thing up and (in the event of a return, down) the stairs is not fun. I wanted something that minimizes that hassle. I read a ton of reviews on so many different companies and machines it felt like i was never going to find the right one. Everybody had such mixed reviews. I spent months looking for the right replacement unit. If i'm going to drop north of $400, because of the cooling capacity i need, it needs to be a really good machine. I needed a unit that would cool most of my apartment, so at least 500sq feet. (it's a poorly insulated/vented NYC apartment in a pre-war building. There's only so much a properly sized unit could do at best, so I'm not expecting miracles.) I didn't want an energy hog, or a machine that sounded like a jet engine. I wanted a company with responsive and good customer service in case things break or the unit arrived damaged. (AC units take a beating in shipping, in my personal experience, so customer service is important) I didn't want a machine that i had to drain or drain frequently (and had hard-to-reach drain ports and a small tank, or worse, leaked). I didn't even want (or need) a machine with a heater. And I definitely didn't want a machine that died after a few months. There are a lot of horror stories out there, and a portable AC unit is not an item that's easy to pack up and return. And then i found this machine, which had glowing reviews, not just here, but a lot of other places, and consistently (not just the most recent reviews). Plus the deal for the unit with the heater was too good to pass up. I bought it. It even arrived a day faster than scheduled.In fairness, i've only had this unit up and running for a few days, however, it is doing really well. It arrived in packaging that was a little worse for wear around the base, and thankfully, the packaging took the brunt of the damage. The unit itself was fine once i unboxed it. It is pretty hefty and bulky, so make sure you have help if you need to get it up stairs.I let it sit for a few days after it arrived to let the coolant settle before turning it on (as you do with refrigerated units). The user manual recommends letting it sit for 4 hours, but I don't think that's enough. Usually 24-48 is standard to let everything settle before hooking it up and powering it on. It's very important to let it sit though, or you will have problems with any AC unit if you turn it on right away without letting the coolant settle. It won't cool and it could damage the motor and internal mechanisms. I feel like that's usually the issue when i read reviews of units not cooling (or not cooling enough, if room size/cooling capacity wasn't the problem) Thankfully, there's no rush because it's winter, but I did want to catch the 60 degree day to just test how it would cool.The only reason I'm giving it four stars instead of 5 was that i had to take a hacksaw to the plastic window extension piece and cut several inches off of it to make it fit, otherwise i wouldn't have been able to get the exhaust tube in because of the overlap. And, also, there's no grated cover for the exhaust hose at the piece, so unless you put your own netting, things can get into the open exhaust hose. (or if there is a grate, it didn't come with the machine) It rolls pretty easily, and is relatively quiet. It is, after all, an AC unit, so it will be fairly audible, even at low speed. That being said, it's quieter than previous units I've owned. Now, because I've only had it for less than a week, I don't know how it does on power consumption, or, obviously long term. I am eager to see how it does in the summer. All i can say is that it keeps the notorious NYC radiator heat at bay really well, for now. It noticeably cooled my living room on that 60 degree day in less than 20 minutes after i turned it on. And I did not wake up in the middle of the night in my own sweat from the radiator heat in my bedroom (sorry, tmi). Those are both wins in my book. Fingers crossed this performance keeps up, because if it does, this is a solid machine.
