24000 Btu 21 SEER Ductless Mini Split DC Inverter Air Conditioner Heat Pump System 208-230 Volt with 15ft Kit (24000 Btu)

This unit is easy to install and works great! It's good on power and has definately done well. I installed this unit in 4 hours with no help.UPDATE: the controlling circuit board is bad, and no one knows where to return for warranty. The part is $389.00 without installation. Please help....

Easy to install and it heats and cools. It's got some great settings also. This is all new to me. Haven't received my electricity bill yet. But I'm using the smart setting which is supposed to save energy

1 1/2 years into owning it and it's still going strong.I did a self install mostly. I bought this as a source of AC and alternative source of heat for my house.This is delivered via freight. So expect large truck/semi delivery and expect it to take awhile. Like 1-2 weeks if I remember correctly.Notes on the install:If you aren't electrically sound call an electrician. I ran a two pole 30 amp circuit breaker with a local 30 amp fuse box per code with 12 guage 4 connector wire (more than necessary for the actual amount of amperage this thing pulls). If all of that sounds like gibberish seriously, call an electrician.The unit install was straight forward with a few hiccups. When drilling the hole for the inlet, outlet, and drain ensure you put a good 20 degree or better downward angle on the hole and ensure the hole sits as bottom right as much as possible while still being covered by the head unit (you can tell by the bracket used to mount to the wall). I put a 10-15 degree on my hole and I noticed that the drain line will back up just a little until gravity takes over and siphons it out. The inlet and outlet are different size compression fittings so if your trying to add more line to the unit take that into consideration. They are odd sized so that it can be distinguished as a mini split supposedly, what this means is that it's hards to find compression fittings. I had to go-to a local screw and nuts supplier (not all places have those within driving distance). You could also order the connectors on Amazon. Important: ensure you get solid brass compression fittings that are milled, not forged. The forged ones that came with the machine broke when I put I put them under full torque.I installed this mounted on the side of my wall as seen in the picture with a wall mount. Wall mount was easy install but if I could do it again I would take and run the extra line and put it on a stand on the ground. The machine is quiet (considering other units) but it still makes noise on the wall. I know I wouldn't hear it at all if it was on the ground.Even though you can do the rest yourself (pressure test, vacuum test, and introduce the refrigerant) you would need a pump and nitrogen rig to do it. I'm a one time install so I borrowed a friend's automotive vacuum and did a simple vacuum test on the system to verify my compression fittings. Then I called a local AC installer (find the company that looks like it's run by a single older guy in his 50's) and he charged me $100 to come out and pressure test, vacuum test (he had the super fancy vacuum rig that takes it down to near perfect vacuum), and introduce the refrigerant. On a side note he said that these machines come loaded with appox. 15% more refrigerant than is needed for the home installers that do the install with only the soap bubble test. I don't recommend that. Pay to have the vacuum test done. If you had a super small leak it could go undetected by the bubble test and cause you to loose refrigerant over time. It'd work for awhile then not (it could be years).Turned on the system and all tests showed working perfectly and has since install.Notes on operation: Heat pump compared to in the wall electric convection heaters is a difference of 40-60$ in electric bills. It's still cheeper to run my pellet stove for heat but this is more convenient. If installing like I did for total house expect some rooms to not heat and cool evenly. I have a single story house with half of the ceilings vaulted and if I leave the doors open in the house the most remote room fluctuates by +- 6-7 degrees. You could solve that issue by buying a multi head unit or using between wall fans. I don't care enough to mess with it. Unit will automatically defrost, but not really. You won't have inches of ice on it unless it really really rains and is cold enough to freeze (unlikely weather situation but I've had it happen) but you will get some fluffy frost on the outside coils if the weather drops over night. Dehumidifier works great, almost scary how well it works but can't use the heat pump while it's dehumidifing (...I shouldn't have to explain) I have an actual dehumidifier but this one easily over powers it. The remote works up to 10ft away, so if you got the time and don't mind less functionality and I'd recommend wiring it up to a thermostat like the nest ones. You can still use the remote control supposedly.Overall thoughts:AC puts out nice cold air. Heat pump puts out nice warm air.Does the job intended without need to spend thousands of dollars on installing ducting. Easy to intermediate level install depending on what you choose to do. Unit looks attractive on the wall, or at least better than I thought it would. I would recommend.

When I started it up I was 12-15 ft away from the unit. I saw the air louvre open but couldn’t hear anything. My cousin said it’s blowing cool air. I switched it to heat, same thing. I couldn’t hear it, Ron had to place his hand in front of the blower , warm air was blowing out. Seems to be very quiet.

Air conditioner works great but the outside unit freezes over when running in heat mode. Made several attempts to get it fixed but customer service sent the same part 3 times. My repair guy said heating unit was bad but they only sent motherboard now warrenty is over so I just have an expensive ac unit.Save yourself and buy a good brand.

Easy to install and seems to pump a lot of heat!

I am an electrical contractor and had no problem installing this unit. I did have an AC contractor come out and do the final connections back and charged. The system is a good product for the price

This unit was put in a 1,000 foot warehouse 2 years ago and it has been running perfectly since then. The unit is very quiet. In fact we have it installed in a space that is sometimes used as a video production set. We can shoot our videos without having to shut the unit off at all. It cools and heats very well. Nothing to complain about, getting ready to purchase another one for another similar warehouse in Texas.EDIT UPDATE: I have now had the unit for 4 years and 2 months and it has failed due to corrosion on the coil that caused a coolant leak. See the attached picture. Also, note the small print in the warranty - "In the case of a coil leak the factory warranty is only 30 days after installation or 45 days from the seller invoice date." In my opinion, a 45 day warranty on a coil leak is way too short. This coil is poorly designed and is easily subject to corrosion. As the water condenses, it gathers on the end caps of the interior heat exchange coil. This in turn, causes leaks. This A/C unit was used in a quiet storage warehouse and was not on all the time. It was a good unit until it failed and for the price I am still not too disappointed. Just know that you probably won't get much more than 4 or 5 years out of this unit due to coil corrosion. Speaking as an engineer, I am shocked that they used zinc plated end caps with copper tubing, just Google "galvanic corrosion". The designers of this unit knew that this was a failure point. That's sad.
