    • 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

    • Very impressed
Size: 12,000 BTU, 115V
Just had the system installed. Done by a professional, but at a low cost because it is quite easy. No special training needed. Right away, love it. It's in the living room/dining room area, so shut off central air most of the day, no need to AC upstairs bedrooms. It runs continuously, so no spikes of AC blast, followed by a warming period. Quiet inside and outside - so nice. Its small size means easy to place and not an eyesore. Has bluetooth. Also, it's 110 voltage plug-in, so much easier to install, without a permit. I've used the better known brands before with great results. So far, this system seems just as good. Only day 2, I'll do an update in a few months. ... 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

This AC unit works great, but is really not a DIY project unless you have experience with AC systems or are just brave and willing to spend lots of extra time and $$. One other very important consideration is the length of the run between your inside unit and outside. The package comes with about 16' My run was just under 40' which added another $130+ for additional piping. I also had to invest in a flare tool, pipe cutter and pipe bender (as I have a few 90 degree turns I had to make). I had a vacuum pump and gauges as I recently put AC in a trans am but I imagine most DIY people would have to invest in that as well. Also the additional piping meant the system did not come with adequate R410 refrigerant so that was needed as well. All told it cost about $300+ additional (and more if you do not have the Vacuum pump and gauges) and more like 10 hours to install if you have a longer run like I did. However once installed, I was impressed by how well it worked and how quite it was. I know the other reviews talk about this but it really is quiet. It's almost impossible to know it's on (when on low settings) and that applies to the outside unit as well. I will put more of these units in, but and focus my design on keeping the piping run to 16' or less. ... show more

    • Do Not Buy - Defective Unit, No Real Warranty Support
Size: 12,000 BTU, 115V
I purchased this Cooper & Hunter mini split and from the moment of installation, it never worked. The unit had a factory weld leak straight out of the box, which means it was defective before I ever turned it on. Instead of honoring their warranty, the distributor (Comfortside) repeatedly brushed me off and tried to blame the installer. Over the course of a week in 96-degree heat, I went back and forth with their “technical support” sending videos, photos, serial numbers, and even mock-ups from my technician proving the leak was at the weld. Their response? “The installer needs to fix that.” That is not a warranty. That is the manufacturer refusing responsibility for their own factory defect. Because they refused to step up, I had to spend nearly $1,000 out of pocket on diagnosis and installation just to deal with their defective product. Even after acknowledging it was a covered defect, they are still insisting I pay shipping costs to replace the unit — which is insulting considering the unit never functioned for a single day. This brand and distributor clearly know how to hide behind fine print while leaving customers stuck with the bill. They may claim compliance with their warranty, but what good is a “warranty” that leaves you without air conditioning in a heatwave and forces you to chase them for weeks just to be told it’s your problem? Save yourself the time, money, and frustration. There are plenty of reputable brands that stand behind their products. Cooper & Hunter and Comfortside are not one of them. Verdict: 1 out of 5 stars. It would be 0 out of 5 stars, but that is not an option. A brand-new unit should never arrive broken, and a warranty should mean more than empty promises and shifting costs back onto the customer. ... show more

    • 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

    • Have a Pro Do the Install
Size: 12,000 BTU, 115V
This is definitely NOT a DIY kit. There are YT videos floating around making it sound like a person can sort of maybe install themselves. Bad idea. Yes, a DIY'r can do all the physical mounting, no issue. But the actual connections? Purging? Leak testing? Leave that to someone with the skill and equipment to do the job correctly. The unit has been running for over a week now. As others say, very quiet. Inside and out. I have mine set up with Alexa. The unit is in a standalone woodshop. It is a small space, 392 sq ft with 9 ft ceilings. I am running the 12K BTU and it has no issues dropping the temp to 70 in 95 degree North Carolina heat. No idea of how well it will do during the winter in regards to heating. The person who did the hook up is a professional. He stated he thought the unit was well made and was happy with some of the features. ... 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
