  • NOT a DIY unit.
Size: 12K BTUs
This may be a great unit but it is NOT a DIY self install unit as it says on the product description.

  • Absolutely a great product at a really good price! Absolutely a great product at a really good price!
Size: 12K BTUs
Absolutely a great product at a really good price. It is not too heavy & comes well packaged. I have been using both heating & cooling for about a month and it is working perfectly. It gets really cold! It is also very quite, inside and out. At 1st I thought the outdoor unit compressor wasn't running, but it was. Do yourself a favor & get the wall bracket kit for the outdoor unit, sold separately, it is worth it. You will need an HVAC expert to install as the evaporator & line set need evacuated & leak checked prior to opening the service valves which releases the refrigerant charge into them. All in all a great system for small areas. ... show more

  • Highly recommend for DIY home insulation
Size: 12K BTUs
Not hard to DIY installation your self. It comes pre charged which is awesome. But you do need know like basic electrical and will need vacuum pump to vacuum the line before opening the value. You will need to do a soap water test to check for leaks also. Over all high recommend. Works great coils and heats. The temperature is in C instead of F so you may have to google what temperature to set it on. ... show more

  • Exceptional price and functionality!
Size: 12K BTUs
Super easy install. Everything is included. Make sure to get your mounts. Vacumning line is recommended, but not nessacary. I vacumned mine and used a good thread sealer to insure no refridgerant leaks as well.
