I used the HVAC service they offer. Both technicians that came out to service my combo unit, we're absolutely outstanding. However, they found out my duct work needed replaced. They set me up with their duct work guys who were supposed to come out and give me an estimate on the job. They were a no show for weeks. Couldn't get ahold of them. Had to call HVAC department directly and get transferred to the guy who leads the crew. He told me he forgot to call me and let me know that he wasn't able to get into my crawl space. Because the hole is to small. He did this supposedly when I wasn't at home. On top of all this all they would have to do is dig the dirt out more to fit into the crawl space. The guy in charge is completely unprofessional and unimaginative. I recommend CDL if you need your unit or furnace looked out. If you need duct work done, I would call else where like I did.
