The technician came out an opened unit and said immediately that we need a new one. I was lectured about the abuse I put machine through and that whoever installed this machine ripped us off because it’s too small for the house. After researching who we brought from 9 years ago I found out it was this company.... 9,000.00 to replace everything and 4,500.00 to replace blower/furnace for all the abuse.... I will call another company....
