Cooper & Hunter 9,000 BTU 115V Single Zone Wall Mount Ductless Mini Split Air Conditioner & Heat Pump – 21.5 SEER2 – 16FT Installation Kit – R-410A Refrigerant Pre-Charged – Inverter

I purchased this .75 ton single zone system for my master bedroom which is always hotter than the rest of the house. So, this is providing supplemental cooling to a room. I was lucky to have an ideal situation of having space on an exterior wall in the room so the heat pump could be placed just on the other side, with an electrical subpanel within 10' of the unit. So, very straight forward install. I purchased a 2 3/4" hole saw to make a clean hole on my interior drywall, then used a small masonry bit to make a series of small holes in a circle on the outer stucco wall, being careful to create a slight downhill slope from inside to outside.Some comments about the instructions that come with the unit:- the description of wiring connections refers to colors that didn't exist with the kit that I purchased. In the end, colors don't matter a bit, just make sure the order is identical for connections 1,2,3 and ground on both sides of the control cable.- the manual mentions in bold letters to be sure to plug the drain in the drain tray using the supplied plug on the side opposite of where the drain hose is coming out, since it is designed to support either left or right side drains. I couldn't find any plug, so I called support. They said ignore, it's already installed at the factory, and since I didn't need to change it to the other side I was fine.- the manual mentions to test your drain by removing the filter screens and pouring water into the tray. This is not obvious where to pour the water. Tech support said to pour over the evap coils. My first try I poured a little too far back and water ran down my wall. Then I poured a little close to the front and water ran out the drain line like it should, with no leaks.- the very good news is that tech support is available. I probably waited about 5 mins on hold to talk to a tech, and they were very helpful.Once the physical installation of the indoor and outdoor units was complete and the circuit was run, I called my HVAC friend to come over and complete the install. He insisted that we cut the stock flares off the lines and reflare the ends, as the factory ends are usually flared with too much pressure resulting in very thin flares. Sure enough, his flares were much thicker than the ones he cut off. Also, we found a piece of loose copper in one of the 5/8" flare nuts which would have caused leaks for sure. He then made the connections and used nitrogen to test the lines to 700psi for 10 mins, then pulled a vacuum for 10 mins. Finally when he was satisfied that all air was purged from the lines he open the valves to charge the system, and it works perfectly. I had pondered doing that part of the job myself by buying a vacuum pump and gauges on Amazon but I think I'm glad that I ended up paying a pro to do it instead. There are some hazards that only someone with a lot of experience would know to look out for.As some other have mentioned these units are unbeleivably quiet. If it weren't for the fact that I can see the fan moving on the heat pump, I wouldn't know it was running at all. It is really that quiet.Hopefully this will provide many many years of comfort!

[Written 2025Mar25]I want to update my review with how impressed I continue to be with this unit.Anyone can look up Phoenix summer weather data for 2023 and (especially) 2024 to see how brutal things were. My office was never above 75 degrees, even with multiple computers running and family sitting at them.I've got it running as I write this because our high today will reach 99 or 100. My wife says she's freezing in here.There's no debate. When this unit goes, I will purchase another C&H unit.-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~-=*=-~[Written 2022Oct19]... six more to go (under the warranty) -- so far, so good. This unit performed like a champ. Very quiet, both inside and out. Lots of cold air.I replaced a 12-year-old Fujitsu Halcyon. Over the last three years it began leaking some coolant oil from the connectors and my A/C guys had to keep topping off the coolant.This unit is for my home office (11' X 15-1/2') on the second story, containing five desktop computers. Usually only two are running most of the day, although it's not uncommon for four to be on at the same time, along with three people present. 2022 wasn't a crazy-heat summer like 2020 (which may have worn out my Fujitsu) but still offered a slew of 110-plus degree days. I set the unit to 72 degrees and the fan speed to high -- meaning it never turns off until I manually do so before going to bed. The C&H unit didn't skip a beat.My A/C guys had never heard of Cooper & Hunter but commented that it looked like a solid piece of equipment, and they are curious to know how it worked. I'll let them know next spring when they come to tune up my A/C systems.If I had to say so today, I would definitely buy another C&H unit. The price is right -- hundreds less than a Fujitsu. It actually cost more for the guys to remove the Fujitsu and install the C&H, than the C&H unit cost itself! (2022 was a bad year to hire contractors -- my guys were booked five weeks out.)

This was a good purchase--so far. I was hesitant because of mixed reviews but the unit arrived on time, was well packaged, installation went well and it works fine. The instructions are clear and came with an accessory kit that is pretty chintzy but mostly does the job (i would be annoyed if i had paid extra for it). The unit works well so far in the spring but hasn't been tested in summer or winter. I purchased an outside wall mount separately on Amazon but the outside unit's feet are an open-side-down U channel and do not fit the width of the wall mount arms or the isolation pads that came with either the mount (circular and too big) or the minisplit (rectangular and probably for floor mounting) - so I had to add additional parts. Not sure if these dimensions are available but something to be prepared for. Also, the lineset pipe-wrap doesn't stick to itself or anything else so be prepared to deal with that. The electrical/control cable ends have connectors on the ends which fit the outside unit, but not the inside unit so they have to be removed. The condensate drain line is pretty flimsy. Little annoying things, but my so far I would buy again.
