    Very impressed

    Posted by Chris H on Jan 31st 2022

    Recently installed one of these units in my garage roughly 500 ft absolutely no complaints keep the units set at 63°, it normally keeps it within one degree two at Max. Customer service has been amazing has answered all my questions. As of right now I have no complaints... We just went through a spell where temps were negative 1° and it's still kept my garage at 63°

    Have two 12,000 units and one 3 unit 27,000 BTU

    I installed this about 4 years ago and everything is working perfect and did the job myself, I had a professional pull the vacuum and hook up lines and I did the rest. Very easy to do. I also am extremely happy with So Good To Buy customer support and always sent me the replacement part no matter how small without any issues whatsoever. The only thing I ever had a problem with is the LED PCB's on the front, but with one call had the part next day, no hassles and great tech support

    Great Buy And great unit

    Posted by Randy on Sep 20th 2018

    Installed this unit myself July 2017 was not difficult for me being an electrician. I did hire the vacuum and leak testing but ran and connected the refrigerant lines myself. I didn't have that much experience with mini splits but after going through an Ohio summer and winter I could not be more happy with the results in both comfort and costs. I am saving about 400 kwh each month and the house was warm in the winter and cool in the summer. Worked out great for me in my home I don't have ductwork and was paying a mint for electric baseboard heat. I was cooling with a window baseboard a/c installed in the wall and can't believe how much more quiet the mini split is. Highly recommend these units. Have not had one problem the vfd on the outside fan works great is saving money.

    Very Happy!!

    Posted by Bill on Sep 5th 2017

    I purchased and installed this unit last year at this time. Sogoodtobuy shipped it on a skid quick and undamaged to my home. I hold a universal certification and have worked with refrigeration most of my working career. The quality of this product is about as good as it gets. The installation went smooth. Startup was flawless. The unit has been flawless for a year straight. I live in New Jersey and my home is around 1,000 square feet. This unit has been the only source of heating and cooling since installation. I am more than happy! I have saved on initial cost, not to mention the savings in my electric bill. Anyone with reasonable mechanical skills should be able to complete an install of this unit.
