I have been a customer of yours now for nearly 5 years. I just had my fall maintenance performed by your service rep, Matt (I did not get Matt's last name).
I wanted you to be aware the Matt provided outstanding service. He took time to explain issues to me in layman's terms. He took his time to thoroughly service both of my units, and repair one of them. He explained what the issue was and why the repair was necessary. When Matt was finished, he went through your standard maintenance checklist and explained the outcome of each of the steps. Matt is truly a professional and an asset to your organization. He has been by far the best tech who has come to my home. I hope that you recognize him in some way and use him as an example of exemplary customer service for your other employees.
