Dear Mr. Baker,
I would like to bring to your attention two fine employees of yours at C&C Air, Pat Sullivan and Mike Skelly. Although your firm has not completed the installation of our entirely new gas conversion HVAC system including duct work and hot water heater, we are compelled to inform you of the quality of the employees you have working for you. While we have dealt with a number of service contractors in the past, Pat and Mike stand above them all. I hope that you recognize and reward them for their great customer service, hard work habits and polite personal communication. They represent your company at the highest level.
Thank you and looking forward to using the new installed system for personal comfort and cost effectiveness.
