"I am very happy to send my recommendation for the service I received from your company, Comfort Zone, Inc., last summer. I have an older air conditioning unit and your service people were very helpful in determining the problem and then seeking the parts and successfully repairing the unit. My contact with the office personnel was very helpful and courteous at all times. Good luck with your endeavor to provide quality service for your clients.
–Mrs. A. J. Holmes
