  • Super Quiet and Efficient!!!! Buy this One!!!!
Size: 24,000 BTU, 230V
I am super happy with this purchase! The unit is super quiet and works fantastically. I bought the 24,000 BTU model to replace both a 24,000 BTU window unit and propane space heater for my 1500 sqft cabin. It is so quiet I have to look at it just to make sure I have it on. Before I had to have my TV at volume level 2,000,000 just to hear over the dumb window unit. I’m pretty sure this mini split will prevent me from suffering hearing loss. Aside from how quiet both the wall unit and the condenser are, this system works so well at keeping a nice comfortable temperature year round. I haven’t had it for a whole year yet but I have used it for both heat and cooling and it is great. To top all of that the kit included for installation made the whole thing a breeze. I installed it all myself with no issues. It does take a decent investment of time to install but it can be accomplished within a casual Saturday and a six pack. If your asking yourself which one should I buy, it’s this one! ... show more

  • Relatively easy install, great function
Size: 9,000 BTU, 230V
It came in good condition and wasn't too hard to install. I was able to do the installation with no help, but I would recommend having a helper to mount the inside unit. Hardest part was carefully bending the copper tubes between the indoor and outdoor units to keep them hidden behind the indoor part where they go through the wall. If you don't hire an HVAC tech to start the system up, you'll need a vacuum pump to evacuate the sytem before opening the valves on the outdoor part to release the charge into the rest of the system. I bought one of the cheaper vacuum pumps from Amazon to do it myself, and used it on this system and another. The unit is very quiet and quick to bring my 12x20' office down from 80° to just above 70°. Since it is a heat pump, it has condensate drains from both the inside and outside units. ... show more

  • Mini split works great
Size: 18,000 BTU, 230V
The olmo 18000 mini split works perfectly. I got because a couple rooms were a little warm while the rest of the house was cool. It seemed like the ac wasn't keeping up July 2024. I got this to supplement my unit. The unit hardly runs at all now. The unit pulls 15 to 20 amps while the mini split only pull about 7 amps. Hope to see this reflected I'm my light bill. The line set was 15 ft and was branded as cooper and hunter. Should be high quality. Did self install in about 3 hours. ... show more

  • Internal leak a year after install
Size: 9,000 BTU, 115V
Worked well for a while, but eventually stopped blowing cold air. Had a repair man come and he found that there was a hole in the outdoor unit which meant all the refrigerant leaked out. The repairs were more than the unit itself. DO NOT BUY.

Great product! Easy install. Wiring could use some better instructions.

  • A month in, it's running great
Size: 9,000 BTU, 115V
I've got a small, old house with no central HVAC. So, it's heated and cooled with split units and window units. This is a huge step up from a heat pump window unit for not much more money. Obviously, this is a lot more difficult to install, but the inclusion of a defrost cycle and its quiet operation make it vastly superior. As to the installation, I did the whole thing myself. I'm no HVAC pro, but I have a vacuum pump and manifold gauges from automotive work. I did have to buy a split unit-specific adapter fitting for my gauges and some electrical stuff, but otherwise what was included was turn key. The instructions could be a little clearer on the relationship between line length and pre-charge amount, with "standard" lengths listed for different regions that are different from the included pre-flared lines. To avoid stressing over the quality of my flares, I went with the full length lines as shipped, vacuumed them out for double the recommended time, removed the gauges, opened the valves at the outdoor unit, and let it rip. It runs great, ice cold on A/C and nice and hot on heat. The remote control is the same as my existing Carrier units, so I can control them all with the same remote. Highly recommended. ... show more

  • Good value, quiet , save money
Size: 24,000 BTU, 230V
Good value, first one I installed 5 years ago,I have installed many this brand and no issues. Many of these are advertised that it is do it yourself installation and can be but i dont recommend purging system instead of pumping lines down and most of these are bad for leaks in linset connections..I use lock seal on fittings and line test with nitrogen to 350 lbs.. I pump down lines to -30lbs with vacuum pump. Unit is factory charged with r410a freon good for 25 feet or so of lineset length. Lineset can be shortened or added to with flare fittings etc or you can roll up if you have to. Foam lineset cover won't last long outdoors. Use a plastic cover or rubatex. I also used wall brackets for outside unit. You can use pad or block to sit on also. No warranty if you install yourself unless you are hvac certified. Very quiet , air was pretty warm at coldest I've seen down to bout 3 degrees. Most of these are identical at this quality just have different labels on them. If installed correctly and sized according will do excellent and pretty efficient even with just 15 seer models. 600 square ft per 12000 btu with decent insulated living area usually bout right for sizing. Rinse out filter once a month and set temp where you comfortable and it works great. ... show more

  • Biy the Warranty
Size: 9,000 BTU, 115V
I bought two of these units and have replaced both under warranty. This particular set was the last replacement unit.. I have gotten just under two years out of each one. Maybe I should have bought name brand units. When they work, they work well. Its a gamble.
