18000 BTU Mini Split Ductless Air Conditioner – 22 SEER - 15’ Lineset & Wiring - 100% Ready to Install - Pre-Charged Inverter Compressor – 1.5 Ton Heat Pump AC/Heating System - USA Parts and Support

There are not many manufactures that make high SEER/HSPF 18K BTU heat pumps unfortunately, but this unit fits the bill perfectly for my desires. Most 18K units are around 17-19 SEER/8-10 HSPF, with this one hitting 23.3 SEER/11.6 HSPF. Efficiency was a factor in my purchase as I could have purchased other 18K BTU units for $400 less. I do wish it had built-in WiFi control, but there are other options available for this need and the Cielo Breez is the recommended option through Air-Con, which I have on order.Installation was very straight forward and similar to other heat pump installs. I used vinyl channeling from Pioneer and a wall bracket from Senville. Both fit perfectly with this unit. The unit comes with nice thick vibration dampers for the feet, and I recommend using them. You don't really hear the outdoor unit operate unless it is under a full heat load, so it is still very pleasant. The electricity savings have been astronomical in using this combined with newer high-efficient window units, so at the very least, the efficiency ratings seem to hold up in real-world usage. I previously used two portable AC's and three traditional window units, so the room for improvement was very large in my case. (Portable single-pipe AC's are the most inefficient air conditioner you can run. They create a negative-pressure in your home that causes outdoor air infiltration, which kills the effectiveness of the unit. A 12K BTU unit can be de-rated as low as 6K BTU of 'actual cooling effectiveness' [referred to as BTU DOE] because of this which makes cooling costs much higher and can make the unit not satisfy the space. Just a quick rant for anyone considering a heat pump, the difference is incredible in both efficiency and effectiveness compared to a portable.)All-in-all, I would definitely buy one of these Air-Con units again and I will consider it for other rooms in my home as well! A very happy customer!

The AirCon 18,000 BTU split system really works great, is easy to install, and is very quiet. Even on high fan speed you have to listen very closely to hear it running. The installation manual covers many models and likely will not have accurate illustrations for your model. The installation manual electrical instructions should be improved. The 18,000 BTU split system comes with two electrical cables to go between the indoor and outdoor units. The indoor unit has tie down clamps for two electrical cables. But you only need one cable between the indoor and outdoor units. Use the one with the red wire. These cables are low voltage cables never run 220 volts into the indoor unit. Even though I never did it before I bought an vacuum pump from Amazon for $50 and a manifold gauge set for $20 and evacuated the copper lines myself. There are many videos on YouTube showing how to get the air out of the lines. If you are handy you can save a lot of time and money by doing it yourself. I am very pleased with the performance of the 18,000 BTU split system and would recommend it to everyone.

I have had this for a few years now and the first two years were fine. But the blower in the indoor unit has developed a squeak. It is getting louder and louder, but there is no practical way to service it because all of these have a terrible design where they are assembled from the back. If the cover could be removed I could probably lubricate or replace the bearing.Adding to the bad design, when I installed it, the lines attach to the back of the unit. You have to attach them and then hang it on the wall. Then connect the condenser side with the compressor and one the valves to fill the system (simplified). Once you fill the system you need to check for leaks. But the connections are behind the unit... So the only way to check is to somehow support it and pull it slightly away from the wall and check for leaks in the cramped space.This is a problem for every mini split I have seen, not just this unit, and is a terrible design. The cover should be removable. The lines should come through the back on either side to the front where they are bent over and attached just under the front cover. The lines can then be installed, serviced, checked for leaks, removed, without removing the unit from the wall. The hardware inside could then be installed and serviced from the front.I cannot recommend this unit as it gets unbearably noisy over time. It functions fine, so the noise problem is unfortunate. But it is rather difficult to fix and probably requires purging the refrigerant. That becomes expensive fast.

This is one of the two mini split heat pumps that I installed at home this fall; the other is a Senville SENA18HF. The outdoor units of Air-Con and Senville are very similar to each other and so probably built in the same factory. The indoor units have more differences with the Air-Con unit being the better one of the two. Although the manual says it is not a DIY unit, it can be done with a vacuum kit. The manual that comes with the unit is not great, but there are some excellent Youtube videos about the installation (for Senville units, but it works just fine for AirCon unit). It is important to watch a few of those and take notes because there are many steps and some of them are nontrivial. A key step is to properly perform vacuum and pressure tests to make sure there is no leak at any of the connections. Take your time and do not rush (or you will regret later). It took me about 7 hours to complete the installation including electrical work.The unit has been running for 2 months to provide heat. It is very quiet (more so than the Senville unit) and electricity consumption has been low although the weather has been mild. So far I am very happy with the AirCon unit.
