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!

Exceptional Value, Easy Installation At 70 years old, this was my first time installing a split-type air conditioner. The manual offered little guidance, but the power wiring diagram clearly showed how to connect the pre-installed standard power cord. After vacuuming the ductwork, I powered it on and it performed exceptionally well. Unexpectedly included accessories: wall caulk, wrapping tape, connection covers, and exterior wall opening protection. It perfectly cools my sunroom in South Texas—where an 8000 BTU window unit previously struggled—and now even provides heating. Incredible value for the price...

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.

Works great! I have used both cooling and heating and this unit climatizes my shop super fast. The only issue is the temperature is cooler than it says. If set to 70 the shop is actually about 65. Very quiet and pulls less current than the window unit it replaced. Installation was super easy. I am very happy with the performance so far. I live in south Louisiana, we can have extreme fluctuations in temperature here ranging from 30 degrees in the morning and 70 degrees by lunch. This unit has done a fabulous job keeping the shop comfortable in both heating and cooling.

Nice and cold! This was my first time setting this up for the house. Other than me making sure the drain hose was not going uphill I’d say a simple setup. Allow enough time to do it right or just have a pro do it less headache. Anyway. Super quiet and my sun room is crispy cold!

Haven't had this unit long enough to say if it cools good but it heats as if it was a cheap space heater, ran on what they call turbo mode for heat which is 88F and max fan. Put it in 350 sq ft living room in 20F-40F outside. It's not freezing but it sure is cold. Recommend avoiding this unit. Just spend a little more and buy a brand with a good name behind it. Let's put it this way I have a very small space heater in my bedroom and when it makes it to hot in my room I open the door to the living room to cool off.

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…
