    • great mini splits
Size: 12,000 BTU, 115V
I bought several MIA 12k and 9K units. They work well are very quiet. I really haven't been able to use the AC but on a 80' day the unit was blowing 34' on the AC setting. While it is 48' outside, the unit was putting out 115' heat. The units were very easy to install in my old 1847 farm house. I had to drill through about 10.5'' of brick to run the line set. I covered the lineset using 4'' down spouting and it looks like it supposed to be there. Great units. I haven't had to use tech support so I can not rate that. I am a DIYer with 99% of my remodel of my house. The most difficult part was running the line set on a 40ft ladder, not hard just a pain. On a smaller home these units would be a breeze to install. If you want a great mini split the Cooper and Hunter is a must!!!! ... show more

    • Awesome unit and it is QUIET, in and out.
Size: 12,000 BTU, 115V
A ton of reviews. Well it is a one ton unit. Watch the videos, the best is AC Service Tech LLC, very detailed. Use the Nylog and a torque wrench, take your time. Granted first day but great this day. I will follow up with an update later on. Qualified for an energy rebate in my area. Going to get another one for the other end of the house. UPDATE: Also purchased the 18,000 BTU unit for my wood shop and it too is whisper quiet and does a fantastic job of humidity and temperature control. Very happy with this brand. May even consider replacing my PTAC units with the mini split as it mounts higher up on the wall and will free up a bit of wall space not to mention its very quiet. UPDATE: Purchased a third unit. 18,000 BTU and also a fourth one also an 18,000 BTU unit. Installed at the very end of May 2022 and First of June 2022. Works well and am very happy with the units. My third unit came with a different remote than the other three and did not have a remote holder, so I made my own. It is usually a set and forget. Not a big deal but just odd. Seems like a new design and works just as well as the other three. Got the install done in a day as I already had the Nylog (recommended) and the vacuum pump and gauges. Also do leak checking when opening the lines with some Big Blu. I would likely go with the spray bottle next time but do like the brush on. Get some Nylog. Have not had a leak and thats after four units installed. Must say the house AC has hardly run, it is at the center of the house and the mini splits take care of the surrounding areas. ... show more

My HVAC guy and I think this is a great unit; and for the price and availability, it's even better. It blows cold and is quiet on the outside and inside. I run a recording studio and this is silent enough on silent mode, I might not turn it off to record (which is unheard of, pun intended). The pictured hardware was our sticking point. It's the preinstalled "hose clamp" for the drain pipe on the inside of the head unit. It was loose and leaked water into the inside of the room. This little piece doesn't, to our eyes, look at all like a hose clamp and it failed miserably. We replaced it with a real clamp and all was well, but having to clean up water, re-attach the baseboard, paint a little, and bring back the technician wasn't the funnest thing in the world. To the manufacturer: fix this little part, please. They cut costs to the tune of maybe $.10, and the result could have been catastrophic. ... show more

    • Worked for less than a day
Size: 12,000 BTU, 115V
Review Image by Chelsea Babers
Let me start by saying it was great at first. We bought it for our newly built small home gym. It was all delivered on time and it was installed the following day of delivery. After installed we were amazed with how quiet it was and how quick it cooled the (small) room. We turned it off for the night. Turned it on the next morning used it for a few hours and then a loud noise came from the unit outside. Husband looked in and the fan completely spun itself off. We thought , no worries things happen, we will call manufacturer and have them send us another fan since nothing else was damaged. It took 3 days to get ahold of someone. When we talked to customer service she asked what happens and for pictures. We sent them and her response was “this doesn’t look like a manufacture issue”. If the customer service knew about the product they would know that when the unit is installed the fan portion doesn’t even need to be accessed at all. Therefore, we received it with it being a MANUFACTURE ISSUE. Fast forward, they agreed to send us a new fan BUT we have to pay for shipping so we paid for two day shipping (which is more than the actual fan blade cost, customer service told us what the cost of the new fan blade would be). Fast forward again , 5 days later and still no fan….. I’m sure the unit will work great when we can actually use it again but after the experience we have had with the customer service as well as having to pay more money for something we haven’t even been able to use is very disappointing ... show more

    • ice cold and whisper quiet
Size: 12,000 BTU, 115V
The first time I saw mini split units was in 2003 at El Greco, in MoBay Jamaica, and I think those were Mitsubishis. Well... let me tell you something. These have come a long way since then. The hardest thing about the installation of this model had nothing to do with the model itself, rather it was drilling out the 70+ year old concrete hole in the wall of the house this was going into. I hired an electrical contractor to install this directly into the electrical panel for me and I'm glad I did (that way I didn't have to mess with plugging and unplugging this unit into the wall, taking up an outlet, etc). Do yourself a favor.. if you know concrete or have a friend that does, pour yourself a slab on the ground to mount this unit onto (the installation kit includes four .25" rubber pads to mount this onto to minimize vibration, though this unit barely vibrates if at all). The compressor itself is whisper quiet, and like others have said in other reviews, unless you put your hand in front of its vent, you won't notice that it's on (aside from the cold air coming out of it). Gone is the loud noise of the fan of a central ac compressor blowing outside, or a wall unit. This thing barely makes any noise. It's also much nicer on your wallet and doesn't suck as much energy as a central ac unit. Before I got this, I would have to sleep with an R2D2 (portable AC on wheels) in my bedroom making noise all night. Since I got this, R2D2 has not been turned on once and my sleep has been much more restful. With The Cooper & Hunter on in the living room, and my 60" fan on low speed in the bedroom, I sleep just fine. If you have the money and a bigger house, instead of going with central air conditioning, consider putting one of these into all of the bedrooms and living room. These would also make a great addition to RVs, no more sleeping on the runway of an airport.. ... show more

    • High expectations shattered. Worth every praise and penny.
Size: 12,000 BTU, 115V
After years of regretting not installing a mini split in my garage office conversion during construction, I finally landed on this one and couldn’t be happier. Where I live, summers are regularly in the triple digits for weeks on end and the 14,000 btu whynter portable ac I had previously did the job close enough (the room would get cool-ish, not cold), but was just so dang loud. Working from home, having the portable ac on during Zoom meetings was just impossible. This Cooper and Hunter 12,000 btu mini split is shockingly efficient at cooling and unbelievably quiet. Seriously, the mini split would actually make objects in my office noticeably cold, not just the air temperature and the unit is not only as whisper quiet as you’ve likely read in other reviews, but even the fan outside is mind boggling quiet as well. I have admittedly high expectations and this thing shattered all of them. I also purchased the WiFi module to control the mini split with their iPhone app expecting just basic functionality (remote control, temperature reading, etc) and was surprised how feature rich and polished even the app was too. I’d happily recommend this brand and unit to anyone interested in a mini split. Beyond satisfied. I will note the stars aligned and I found a very competent, licensed HVAC technician before purchasing this and you absolutely need a professional to install. The HVAC tech license number is also needed to register the unit for the warranty (an ultra easy single page online form to fill out - literally just a few lines) so just be ready to submit that within 60 days of install. Not a hassle at all. Like 5 mins of your time. Worth it. ... show more
