Rated 3.8 out of 5 by 6 reviewers.
Rated 3 out of 5 by Not ready for prime time poor customer support and poor manual I bought this product back in June of 2013 and I've had it now running for over a year. Twice the unit has leaked the 410A and needed to be reached due to a leak. The unit is also leaking water out the front right side on the air handler (the piece inside the house that blows out the air). I checked the drainage and that's not the issue as the water is coming out the side opposite to where the drainage hose is located. This was installed by a licenses HVAC tech however the costs add up for the 410A and trip charge for the tech. The good is I bought a Home Warranty for this unit after the first issue happened. So now its only a $75 charge and the 410A or whatever else is wrong with it is covered. June 30, 2014
Rated 3 out of 5 by Some issues to consider One review here mentioned a water leak at the air handler. I just serviced a unit that had this problem. The problem was a section of the line set was exposed and condensation was forming and leaking down the wall. The fix is to wrap foam tape around the exposed copper line. The thing that worries me about this Unit is the Lines have threaded fittings instead of brazed connections. They are more prone to leak. July 20, 2014
Rated 3 out of 5 by Not bad but has some issues We have owned this unit now for about two months. The first month the unit was out of service as the installer had a difficult time with the coolant connections. Twice the coolant leaked out and had to be refilled. The unit had an error code that was not listed in the manual but the servicer was able to figure out the issue. Once the coolant leak was stopped, the unit has worked fine. I can't say if this was a poor install or poor design. But I can say that the HVAC installer was an HVAC tech - not me or a friend. Also, the tech did not have much experience installing these unit types. The unit is very quiet and cools quickly and appears to have many features. Buyers need to be aware of two issues. First, the manual is not written well and there are literally whole sections that make no sense. There are several features that I can't even figure out for sure what they do even after reading the manual. Second, when I called the service/support line on a week end all I received was a busy signal. In a nut shell, poor documentation and poor support. The mini-split concept was a perfect application for what I was doing (a home work shop) but I am not sure this brand is yet ready for prime time. I am a little surprised that Home Depot did not vet the product/vendor better before offering the product. One read of the manual and/or a quick call to the help line and I doubt they would have decided to carry the product. Especially surprising given the price point. Note that I paid roughly $1,500 for installation on top of the product price. June 3, 2014
