I use it to cool down a 432 square foot living area and from the start up to comfortable cool takes five minutes. I can honestly say it's the best air conditioner I ever installed for myself. I'm 72 years old and I installed it myself.

Are the indoor and outdoor components included?
Yes, both the indoor wall mounted air handler and the outdoor condenser are included, along with the line set and communicating wire to connect the two units.
How efficient is this unit at low temperatures such as 10- 20F?
So far the lowest temperature that I have experienced with this unit is -7 Celsius which is 19.4 Fahrenheit and it was still making adequate heat but it was noted that there was a reduction in the heat output. You should have a supplemental or backup heat source if you live in an area where you experience consistent temps near or below freezing!
Does the inside unit come with mounting brackets?
Yes, and a nice template to drill the holes for the mounting bracket.
Does the system include the communication wire to connect the indoor to the outdoor unit?
Yes, every MRCOOL DIY® includes the communication wire to connect the air handler, the indoor unit, and the condenser, the outdoor unit.
