Great Customer Service from Cardinal Heating & Cooling all the way around from the techs, the office, to the installers. They kept me informed of the problems I was having with my heatpump while I was working because I was unable to be where at the time. I talked to the tech, the office and even to the owner. That's great feeling when people are available for you to talk to when you are busy and need someone you can trust in. Thank you for your help.
