    Works well, but is a bit loud.

    • Verified PurchaserVerified Purchase

    Reviewing the Whynter ARC-14S, portable AC unit. Pros: It works well for the room size (~12'x15'x10'). Very powerful and cools effectively. Easy to wheel around. Intake and Exhaust hoses extend quite a bit, so you have a little flexibility in placing the unit. Maintained temperature well. Cons: It's pretty loud. The light from the control panel is very bright and you cannot turn it (the panel) off. It is a big unit, and very heavy if you need to lift it. Comments: It's a lot taller than I expected for some reason. The thing to remember is that it's a portable unit. By default, they're not as good as a window unit, ductless split, or other permanently installed unit. However, the advantage is that they're portable. You can move them around, use it just for those few hot days, or move it to where you may need some additional cooling. I got this to cool my bedroom at night so I can sleep more comfortably. My HOA doesn't allow window units, and I'd rather not run the central AC to cool the whole house when all I need it for is my bedroom at night. It's a bit large for the size of my room, however, the recommended room sizes tend to be optimistic. (e.g. a unit that says it's for 500 sq.ft. is not going to handle that much space except under optimum conditions). It's noticeably louder than the fan I was using in the window to try to keep the air moving. I can still sleep with it going on as it's more or less just white noise, but if you're a light sleeper, or sensitive to noise you can forget it. The blue light is actually more distracting to me. It's nearly bright enough to read by in a darkened room, and there's no way to turn it off. However, that is easily remedied by putting a couple of post-it notes over the panel. There is no way to muffle the noise however. The compressor is louder than the fan inside the unit, so the fan setting doesn't really matter while the compressor is running. The fan by itself is reasonably quiet in the lowest mode. The window kit that comes with the unit extends to a maximum of about 46". That was about 8" shorter than my vertical sliding window opening. The first night I filled the gap with a piece of cardboard, which worked OK. However, I was a little concerned about losing the cool air through the plastic/cardboard, so I purchased some rigid insulating foam board from the hardware store, and am using just the hose connection panel with the remaining gap filled by the foam. I would recommend at least using some foam insulating tape (not included) around the edges of the window kit for a better seal. Overall, I'm pleased with the unit. The two things I'd wish for would be for it to be quieter, and have some way of turning off the panel light. If you're not trying to use it in your bedroom, I would think that this would be excellent for spot-cooling any reasonably sized room.

    Save Your "TIME and MONEY" This Product will fail


    I have about 35 years of experience in the Computer IT / Electronic Engineering Design, Development and Production Industries. Starting in May of 2014 one of my associates suggested that I try out some of the new Portable AC technologies of which could allow me as a technology consultant to use, test and then recommend to my clients. Myself along with my clients ranging from real-estate owners to large scale warehouse businesses have a common need which is the ability to cool one small room without having to run central air and cool the whole building. Also portable AC(s) can serve as a single room backup in the event of central air failure. I purchased my first Whynter ARC-14S in May 2014 with the expectation of purchasing 3 more at another location if I like the first one. By March of 2015 the first ARC-14S was still performing great so I purchased 3 more (two ARC-14SH and one ARC-12SH). Now In June 2015, the very first one stopped working and considering it was just after the warranty expiration, I decided to replace it rather than try to get it fixed because Whynter's return policy states that you need to do the following: 1. Box it up in the original packaging (if you still have it). 2. Pay two-way shipping if it is over 2 months old ( Labor and Parts are covered) 3. Pay labor if it is out of 1 yr warranty (only compressor is covered) For a busy executive with a $450.00 item this process is not worth it. Shipping will cost $250.00 Now the last straw is that in August of 2015, I purchased and replaced the first one with a ARC-143MX which performed perfect until Sept 24th 2015 when it started to Draw 18 amps / 2250 watts of power from it's dedicated circuit before it shuts itself down. I have high level computer protection and monitoring on all circuits so I get an accurate reading of the electronic environment in regards to any event.

    Very disappointed overall


    Very disappointed for several reasons. When everything was unpacked, I noticed the air vent on the top of the unit wouldn’t stay up. After waiting the obligatory 4 hours (which gives you plenty of time to attach both hoses to the window attachment, and then get that snug in the window with some foam insulation tape) I turned the AC on. Initially there was a bit of rattling and it spit out the missing (and broken) pieces needed to make the air vent work. Without them the air vent falls closed and the air is just directed vertically up through the remaining air gap. However, it didn’t sound too bad (I had the fan on high) until, that was, the compressor kicked in. Yes, the compressor is a bit louder than I expected, but the worst part is the added noise of the second air fan cooling the compressor and the additional air movement through the air hoses. This makes the AC very noisy overall, and very noticeable when it’s cooling. The following is a direct quotation from the Instruction Manual “In cooling mode, the difference in noise level between the 3 fan speeds is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should be able to hear the difference between high and low fan speed settings.” What they’re saying indirectly is that the noise made while the compressor is on is so loud, it drowns out the difference in noise made between low and high fan speeds. The AC is going back because of the broken air vent, but I doubt I could get used to or tolerate the noise level. Interestingly, now sold out online. It does appear to cool well, but I was expecting more for 14,000 BTUs. Hopefully, other’s experiences are better than mine!

    I mainly use this during the night. It's super hot and humid here in Ft Worth during the summer. This unit works great! I used to sleep with a box fan going all night to kill noise. Now with this AC unit, i can turn off my central AC at night, and just have this unit on and make my room super cold. The dehumidifier works great as well. My bedroom is no longer stuffy. Yes, this makes noise. Expect it to. The bad part about this unit is the window connection. It's not energy efficient at all. Hot air comes in from outside in so many places around this piece. I made my own because of this. Just got some MDF, cut it to my window size, cut a couple holes for the hoses, screwed the hose connection pieces to the MDF around the cut holes, used caulk to seal the hose connectors to the MDF, and finally some weather stripping around the perimeter. Air no longer gets by. I highly recommend this unit. Fantastic.

    Very Nice Unit - Works Great

    • Verified PurchaserVerified Purchase

    Let's start with, it is exactly what is was supposed to be. The unit was packed well; arrived in good shape; was easy and quick to set-up; and, worked extremely well from the first moment it was turned on. Our application is in a datacenter as targeted cooling; it pretty much runs 24 x 7 and provides anticipated cooling. The unit is well built, controls are simple and functional, the dual hoses (intake / output) make it nice for assuring best area cooling effectiveness. The noise levels are lower than anticipated and the ability of the unit to dry condensate is good (no excess water build up). From everything I have seen and experienced for the last month or so, I would highly recommend the unit and as importantly, I would buy another one tomorrow if we needed it.

    Terrible Product

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    I do not know what they used to measure the BTU output of this product, but it does NOT put out 14,000 BTU. One thing I’ve read is window units pump out more BTU’s than a portable unit. Well in any case, they should be measured the same. Honestly, the first night it struggled to cool a 12x12 room with 8 ½ foot ceiling. And on top of that you have to manually empty out the water collection tank every 4-6 hours. Our old 8,000 BTU window unit could cool off our room in an hour or less and I didn’t have to drag it all the way across our apartment to empty the water out of it every night. Also, I noticed the build quality was a little suspicious at best. I looked down through the main vent and some of the plastic clips were not even connected where they were suppose to go as well as some of the screws were not attached. No we have and LG unit and it does the job however, it creates a lot of condensation and starts spitting water out the main vent after about 2 hours… But at least I dont have to drain it! So, do what you will with that info…

    Don't buy this Item

    • My Best Buy® MemberMember

    Bought this item 5 days ago because previously a owned a similar AC from a different manufacturer that cooled perfectly and I let this new AC sit for over 5 hours (manual said 4 ) before hooking it up. Packaging by the manufacturer was horrendous and falling apart! Product did not seem to be damaged. Everything works except the most important thing NO COOLING. Brings the temperature down maybe 2 degrees when the outside temperature is 65, 70 or 85 no difference. Called Best buy to send it back and they are picking it up tomorrow. When I boxed the unit I noticed it had been leaking a small amount of a greasy substance that I also found on the lower outside part of the unit by the motor (about 10 inches high and 20 inches wide. The unit is useless and I ordered a different brand. I will post my comments on that new purchase in a few days. BTW Best buy immediately took care of the shipping back! Great service Best Buy.

    So far so good


    Bought the Frigidaire 9000 BTU single hose unit it created a negative air pressure in my apartment and never really cooled the whole apt. Took it back to Best Buy and they refunded my money with no questions. I then ordered this unit on line at the best buy store the sales guy actually put the order in I was informed it would take 10 to 14 days for delivery. I put the order in on Sunday and when I got home on Tuesday it was on my doorstep. Hooked it up via the you tube video and violaa cold air. All is good now happy today and loved the 2 day delivery.
