Actually installed unit 15 months ago so have been through a winter and summer cycle. I'm very pleased with unit - very quiet and does a good job of heating / cooling my detached 2 car plus garage / workshop. Only difficulity is maintaining Wi- Fi connection, and that is more likely due to location - detached garage with Wi-Fi extender.
Easy install works great. Does defrost mode when really cold quite often
Easy to install. Good to have two sets of hands for the interior unit but do able alone. My electric bill went down using the 24000 btu unit instead of two small window AC units. And it does a much better job. The heat works well and is also much cheaper than running my oil furnace.
Very easy installation less than 2hrs by myself even going to town for electrical wire.installed unit ran electrical wire, connected copper lines,turned on end of story hadn't touched it since settings temp.can not hardly hear unit running very quiet.i will be installing more units throughout my house.i live in the south and it's handling the heat well
Very good product. The AC works wonderful just waiting on heating season to see its full potential
Great diy a/c
Easy to install! Great a/c
February 07, 2019Tracy asked:
Will it heat with temperatures at or below 0F?
These units can produce heat to around 5 degrees. Thanks!
July 07, 2018Mike asked:
Are shorter than 25 ft line sets available ?
Unfortunately there are not shorter line sets. What most customers do with the excess is roll the line set together and tie it to the condenser. Thanks!
August 01, 2017Mark asked:
Length of line set? Can longer line sets be purchased?
The line set on this unit is 25 feet long. Unfortunately the line set cannot be made longer or shorter. Thanks!
April 17, 2017Ben asked:
How much square feet does this unit cover?
This unit will cover up to 750 sq ft of space. Thanks!
April 10, 2017Kyle asked:
How does the indoor fan modulate its speed? Also, how is the defrost managed?
It does modulate fan speed. Unless you turn the power off entirely the fan will run even once your temperature set point is met. It will run very slowly and silently and the outdoor compressor will be off. The indoor fan always runs when on to gather the ambient temperature of the room. It runs at a fraction of an amp. As for defrost it will turn on the cooling mode at very low fan with the air vane deflecting the slight cool away from the conditioned space until the outdoor coils are melted.

Can two sets of line be paired together for longer installation
Unfortunately, you cannot use more than one line set. Thanks!
