Professional, prompt, patient and courteous, from Bob in sales to the office staff to the installers. Installed A/C unit and I could not be more pleased. Gave me all necessary info to make a decision on which unit to purchase, and everything went smoothly. The installers completed the job when promised and they did an excellent job of cleaning up after themselves, which is appreciated. The city inspector even commented on what a great job they did. That says it all to me!
