Gasbye Dual Hose Portable Air Conditioner, [2026 Upgraded] Full DC Inverter Compressor, Energy-Saving 13.6 CEER, Low Noise (45dB), Cools Room up to 500 Sq.Ft., Backlit Remote Control, 14,000BTU, White

TLDR: This is an excellent, quiet portable air conditioner with lots of flexibility for different use cases. The remote is confusing and persnickety and you'll want to throw it in the trash--still 5 stars in my book. I bought this to replace an aging Danby portable air conditioner (from about 2012) with fewer BTUs and a single-hose design. Although it cooled my 600 sq ft bedroom adequately, the random compressor jolts could wake the dead (let alone the bedroom's sleeping occupants). Some research turned me on to two new developments in portable AC technology. First: dual hoses. One hose is an intake, bringing fresh air from outside, and the other exhausts warm air from the space you're trying to cool. The main advantage is that by having a separate intake, you eliminate a "negative pressure" environment. (With a single hose exhausting warm air, it creates a pressure imbalance between inside and outside, such that the warm air outside finds ways to seep in to your room.) This keeps your AC more efficient even as it works less to cool. The downside is that the exhause hose can get pretty hot--but there is a way around that you can in my pictures. You can now buy a pair of wrap-around sleeves for your hoses, for about $20, that insulate them quite well. A temp gun showed that the temperature delta between a wrapped and unwrapped hose is about twenty degrees. They can be a bear to get on, but the velcro straps are quite strong and they stay on well. If you only have the budget and patience to wrap one hose, do the exhaust. The other new technology I discovered is an inverter compressor. In my old Danby unit, the compressor was either on or off. It would be like if the accelerator in your car could only go to 60mph, and then back to 0pmh when you pushed the brake. This not only uses a lot of energy, it's also very loud and jarring when it suddenly kicks on. Since many people are using these to stay comfortable while sleeping through a hot summer, this is far from ideal. With this Gasbye unit, you can set it to run this way with "Turbo" mode. The remote has a button for this, or you can hold down the "Fan Speed" button for 3 seconds on the unit. "Turbo" mode also maxes the fan speed. But even in "Turbo" mode, the Gasbye is noticeably quieter than my Danby unit. In fact, it's not much louder than my white noise machine, and not very unpleasant at all. There is also a standard "Cool" mode, which allows you to set one of three fan speeds, or you can set the fan speed to "Auto." There is also a dedicated "Inverter" mode that you can set by holding down the "Mode" button for 3 seconds. This allows the compressor to ramp down to save energy and reduce noise. For any of these modes, you can still set a goal temperature--the unit just gets there more or less aggressively depending on the mode you select. The manual recommends setting the unit to "Turbo" two hours before bedtime and then changing it to "Inverter" when you go to bed to maintain the temperature. My bedroom is about 600 sq ft, and I can tell you that this unit only needs about 20 minutes to get it down to about 70 degrees. Switching to inverter mode has kept the temperature there overnight without freezing me out. (That happened the first night when I left it on Turbo.) Although it's not even June, I got to test this recently when my heat pump went out, and the temperature in my bedroom got up near 80 by the end of the day. I will be eager to see how it does in July in August, when it really heats up in central Kentucky. It also gets very humid, and this may affect the performance. It has been raining and quite humid already in the past week, but I have not had to drain it. The manual says the unit has a vaporization system that generally precludes the need to drain, although some reviewers have found otherwise. I will update this review if anything changes this summer. By the way, it also has a dehumidifier mode. The compressor still runs in this mode and blows out cool air, because that's just how a dehumidifier works. (That's a vast oversimplification; check out the "Technology Connections" YouTube channel for a much better explanation.) The unit is quite big, as you might expect for something that requires a lot of big, heavy components. It fits well by my bedroom window, but the install was a little challenging. I had to cut the panel with the openings for the hoses to fit my window properly, and then join it with screws to the smaller of the extenders. (The unit comes with the main panel and two extenders of different sizes.) It was hard to get the screw in the bottom of the two panels. Because of my window design, I had to get the panels where I needed them first, and then awkwardly come at it from the back and top while lining up the correct screw holes in the panels without being able to see them. Once I finally did that, the rest wasn't too bad. It comes with two different types of foam. There is an adhesive strip you can put on the top of your panel (or the bottom of the window that closes on top of it) and on the bottom of your panel or your window sill. There is another piece of non-adhesive foam you can stuff into the gap between your bottom and top window panes. It was a little small for my application, so I reused the thicker foam I used with my old portable AC unit. All of this together seals the gaps relatively well, although there is a little bit of daylight between the top of the panel and the window. I have never found a way around this, at least not one I was willing to put the work in to try. Other reviewers have put together some excellent DIY solutions. Their pictures and explanations are more helpful than anything you'll find in the Gasbye manual or on YouTube. I also bought a silicone mat that fits perfectly underneath it. It is 20''X20''X0.6 and cost about $15. I bought this in case the unit leaked water from the drainage port, or in case it flowed out when I opened the drain plug. Neither of these things have happened, but it gives me some peace of mind. The hose sleeves are made for 5" or 5.9" hoses; these hoses are 5.9". Because I didn't extend them all the way, I had to do a lot of finagling to wrap them. In fact, I discovered that I had to attach the hoses, bend them into the shape I needed for my installation, then carefully remove them without changing their size and shape, then wrap the sleeves and fold back the excess material, then re-install the hoses. Finally, I put the three velcro straps on each one to keep them in place. I did a good job covering almost the entire exhause hose, which is the most important. I couldn't get quite as much of the intake covered. That was the first one I did, so that's probably why. But I was too lazy to start over, at least for now. By the way, the unit is pretty heavy, at around 40 lbs. It's manageable to move into position for most people--I had to get it up a flight of spiral stairs, which was difficult but doable. You are not going to want to move this around much once you install it, so figure out your positioning before you start. To sum up, I am very pleased with this Gasbye unit. It cools my bedroom down quickly and keeps it comfortable without making a lot of unpleasant noise. It is much more powerful and flexible than my old Danby unit. It's a little expensive at north of $500, but it's worth the price in my opinion. My only real gripe with it is the remote. The first red flag is this statement in the manual: "Contrary to a common misconception, the remote doesn't just transmit the last pressed button's information to the air conditioner. Instead, it communicates all the stored settings currently displayed on the screen." Even if you're paying attention, this is confusing--and when you actually try to use it, it's infuriating. And because the remote needs a pretty narrow line of sight to the unit, it's very easy to press a bunch of buttons, and then when you achieve the needed line of sight, I guess they all get sent at once to the unit, essentially creating mayhem. All I know is, button presses often don't achieve what I expect them to. And sometimes, even when just pressing one button while pointing the remote directly at the unit, it does something different than the button indicates. It's maddening enough that I have basically stopped using the remote. This is fine for me, because as mentioned, the buttons and the instructions for using them on the unit itself are very good. One exception: I cannot find a way to turn on "continuous fan" on the unit itself; this seems to only be possible with the remote. But I had to fight with the buttons to even get this to work, so I probably just won't be using that.

Powerful and Efficient – Exceeded Expectations! I’ve been using the Gatsby dual-hose portable AC for a few weeks now, and I’m seriously impressed. It cools my room (around 300 sq ft) in minutes, and the dual-hose setup really makes a difference — faster cooling and better airflow compared to single-hose units. The build quality feels solid, and setup was super easy. No tools, no hassle — just plug it in and attach the hoses to the window kit. I also love that it’s easy to move between rooms thanks to the wheels. Noise level is surprisingly low for how powerful it is. I can sleep and work without distractions. If you’re looking for a reliable and effective AC unit, this one’s a winner. Definitely worth the price!

Installation was very easy. The unit is extremely efficient with quiet noise levels and I find myself primarily using the inverter mode during the day and night. The unit blows strong, very cold air and cools down the rooms very quickly. I like that the unit self adjusts fan speed if set on Auto to optimize ambient conditions and temperature setting. I am very satisfied with the solid construction of the unit and windows kit as both are high quality materials. The window panels did not quite fit without overlapping the exhaust vent so I had to cut about 2 inches. The remote control is functional though is the only area I think the company can make a few improvements. The Instruction manual is easy to understand with pictures and concisely worded. Customer service seems to be very proactive and responds quickly. The 3 year warranty is outstanding is a primary reason for my decision to purchase this unit. Extremely impressed with the overall product and company support and will definitely consider Gasbye in my future product decisions.

Works great, easy installation. It keeps our very small (approximately 600 sq feet) apartment cool, and the room that it’s in is cold. The noise is noticeable, but it’s not too loud and it’s not annoying, it’s a steady sound. I bought it because we had a different product from this company and have had great customer service. We have been using it for a month, so far so good.

Easily one of the best portable units you can buy for the money. It has an inverter drive that does quiet it down a good bit. Im still on the fence if its worth it for the noise reduction. It does diminish the volume of air being blown. And at that point you might as well get a smaller window unit. But the point is to have the ability to pump out a large volume to cool the room down quick and than hit the inverter to settle quiet mode to go to sleep after the temperature comes down. I think the dual hose does make a difference, but it still creates a vacuum in the room and pushes some air out the window, so you have to insulate your room well from drafts. Invest in hose insulation it does help quite a bit to reduce thermal heat radiating of the hose. So basically this unit can turn into a 6000 btu a/c up to a 12000 btu a/c. I did weasure wattage in inverter mode its roughly 600 watts at 5.5 amps. In turbo mode which is max/full throttle it will pull about 900 watts at 7.7 amps.

I did a lot of research before deciding to go with the Gasbye portable AC. It was an investment, and I wanted to feel confident making the decision. I had been wanting to switch to a dual-hose system, and this unit fits the bill perfectly. I was able to install and set it up myself with no issues. It's sturdily built, and the design is well thought out (the air outlet louver even glides shut when not in use... very cool! [no pun intended]). There's a great deal of flexibility in configuring the control panel to fit your situation perfectly, including mode, fan speed, auto, and even a *turbo* mode. There's a remote included, but I haven't used it. I've been very impressed with the performance of this AC to easily cool an open floorplan area that includes a 15x20 living room, plus a dining area, 2 short hallways, and a galley kitchen. I compare that to the single-hose unit of another brand that I had before, which created a vacuum and struggled to cool this area even when set to max. The Gasbye is in a different league altogether from that, and I am sure it could handle an even larger space. Another welcome difference with this machine is that it's very quiet compared to my prior unit. The Gasbye, even with the fan on high, is at least 50% quieter, which my ears appreciate very much! I've used it in AC mode only and have seen no hint of any kind of water leakage. If any issues occur with use over a greater time, I will update this review, but given my experience so far, I highly recommend this unit without hesitation.

This unit is the best portable a/c i have ever purchased. I just started using with the ny summer heatwave and it is more than sufficient at cooling the area. Setup was easy and it seems like a very solid unit. I did email my info to vendor for additional warranty and the rep (amy) was helpful and responsive. Hopefully it will last much longer than the two Whynter units i had previously.

Have had this unit for about 3 weeks, so far it has performed as promised. Seems like excellent quality. Exceptionally quiet. Easy to set up. Will do another review as temps outside get higher in coming weeks.
