I used them two years ago when I first moved into the house. Loved the service. He didn't try to sell anything. He was honest, quick and through. I thought I would recommend him to my inlaws who had just relocated from Tennessee to Charlotte. Well.... when he arrived for the service call he proceeded to ask if they were all vaccinated. After a very brief conversation he told them they had to find someone else. They will discriminate against you!! You have no right to ask that question sir. Isn't that a violation of hippa law to ask questions about peoples medical status?? Shame on you! What have we become? I will never recommend them to anyone. I will just write some terrific reviews.
