I purchased the Mountman 12000 BTU Mini Split AC/Heating System almost 2 weeks ago, and I couldn’t be happier with it. It cools my space down quickly during hot days and provides consistent when weather cool down. The temperature control is very precise, and the remote makes it super convenient to adjust settings without getting up. The unit runs incredibly quiet — barely noticeable even at night — which is a huge plus for me since it’s installed in my bedroom. The design is sleek and modern, and it blends well with the rest of the room. Installation was pretty straightforward, and the included instructions were clear and easy to follow. I also appreciate how energy efficient it is. I’ve noticed a drop in my electricity bill compared to my old window AC unit, and the heating function works just as efficiently. Overall, this Mountman mini split system delivers great performance, quality, and comfort. Definitely worth every penny and highly recommended for anyone looking for a reliable year-round climate control solution!

This is the best air conditioner I've ever bought. It was almost $100 cheaper than other stores, and I installed it exactly as instructed on YouTube—I even bought a vacuum pump specifically—and the installation was a complete success. The cooling effect is excellent, and it's quite energy-efficient, perfect for my room. Now I can finally ditch my electric heater and small window air conditioner; it's fantastic! If I need an air conditioner again in the future, I will definitely buy another one. It was very satisfying to install it myself..

This air conditioner is fantastic! I’ve finally escaped the hassle of those clunky window-mounted units. It mounts neatly on the wall—looking sleek and saving space—and, most importantly, it operates completely silently. I absolutely love it! It packs a real punch; when I switch on the heating, the room warms up in no time, and it powers up incredibly fast. We’re still experiencing weather here that requires heating, so having this unit has been incredibly convenient. Its dual heating and cooling functionality is a huge plus; while I haven't needed the cooling function yet, I know I can easily switch to it once the weather heats up. Given how quickly the heating kicks in, I expect the cooling will be just as fast. It works perfectly for our restaurant setting—I highly recommend it!

I’ve been really happy with this mini split so far. It has strong cooling and heating performance, but still stays very energy efficient, which helped keep my electricity usage lower than I expected. It also runs much quieter than I thought, so it doesn’t disturb daily life at all. The installation process was easier than expected, especially with the included installation kit. Overall, it’s a great value for the price.

works good considering I have it in an uninsulated garage, so it takes a while to feel a real difference. I usually start it about an hour before I have to go out and work. Beats the small AC unit I had and its a lot safer than the 40 + year old gas heater that hung from the ceiling. in the depth of winter in would raise the temp about 20 degrees but I know if I insulated it would do better

It’s powerful enough to comfortably cool (and heat!) my space up to around 750 sq. ft., and it does it quickly. Within minutes, the room temperature noticeably changes, and once it reaches the set point, the inverter technology keeps it steady without constantly cycling on and off. The 19 SEER2 efficiency rating really shows in day-to-day use. It runs quietly and doesn’t spike the electric bill like older window units or central systems. The 115V setup was perfect for my home, and the pre-charged condenser plus included installation kit made the process much smoother than expected (especially if you’re working with a professional installer). I also love having both cooling and heating in one system. The heat pump works great during chilly mornings, so I don’t have to switch to a separate heater. It’s a clean, ductless look, and the indoor unit blends in nicely on the wall. Overall, this mini split is energy-efficient, quiet, and powerful. If you’re looking for a reliable all-in-one heating and cooling solution for a medium-sized room, this is absolutely worth it.

So far so good I installed it in my two car garage that’s been insulated and drywalled. Took just a couple minutes to heat up the garage. We have been looking at these for a couple years. I was nervous because I’ve never installed anything like this. But I wouldn’t hesitate to diy this unit. It was super easy and there’s a lot of people that say you need a dedicated breaker for this. I searched for videos like crazy and never found one that showed splicing in a cord so the unit could be plugged into an outlet. So I just went ahead and took the chance I installed three more outlets in my garage, there was only one outlet in the garage so the garage is running off a 15amp breaker from the house and I’ve got a tv a printer phone chargers obviously the light in the garage and I charge my golf cart from an outlet from the garage with no issues. When I had a window A/C unit it used to almost trip the breaker in the garage. I would definitely recommend getting this unit. It’s very cheap and it seems to work very well so far…

The unit installed easily enough and cools , my issue is with the remote, I have had the unit installed about 6 months and I still cannot figure out if it has an "auto" feature. Nothing on the remote display, and buttons says "auto". No matter what temperature I set it at on cool mode, it always runs, it never shuts down. The instructions, nor install videos have any meaningful instructions on how to use the remote, even people who have made youtube videos, are just guessing when playing with the remote due to the lack of clarity with its use and no available, "this is what this symbol means", "this is how to set to auto", instructions anywhere.
