The Good: We used them for purchase and install of our central heat. They were quick, friendly, and efficient at a reasonable price. Wham bam thank you mam and it was all done! I highly recommend them for new installations. The Bad: I called them recently to service an existing split A/C system. Communications were very poor until we complained. For the first week we struggled to know where it was at and we had to chase them for responses. They eventually had us prepay for a part that was the wrong one when it arrived. After about two and half weeks of messing around we moved on to a brand endorsed dealer.
