Bought this unit a few weeks ago. It outperforms the units we've bought in the past.
I have a 2000 sqft living space, and when the temperature was 93 °F outside, this unit kept the inside at a comfortable 74 °F. Quiet and very easy to operate. Let's see the bill this month.
And yep, the service is incredible. They have staff to contact me soon after I order and then schedule site checking and installation. Everything is perfect!
