The guys were very good at getting here being clean and quick. We did not get any real instruction on how to use the machine. I wish they could have spent a little time explaining. Also, they needed to take a door off to get machine in and did not put it back on. It was a quote of $650 for them to arrange to put it back on (molding and door) Seems way steep for a job like that. Also did not have the bottom mount for the thermostat with them. I understand this was a home warranty job, however it was still a lot of out of pocket $ for us...Overall, was a good job, just a little unhappy with the door thing :(.
