Our electric bill doubled. We called Knight after looking at HVAC companies that are Rosie on the House certified. Mark came out and looked everything over. He wasn't able to fix the issue (our fault), but he was able to disable the heater which was erroneously turning on with the AC.
He also illustrated the fixes needed, along with non-essential, but valuable options to improve the system. Mark helped us out today, and we greatly appreciate it. Thanks Knight!
