Rated #1 Again

I had a new a/c installed in May. I want to express my gratitude for the contractor that installed my new unit. He did an absolutely amazing job. He answered all of my questions, was fast, friendly and made a very stressful situation easy.

I also noticed he was training someone at the same time. He did amazing with that as well, a few times I overheard him teaching the younger man the right way to do something. That is commendable to see this day and age.

I also want to thank the gentleman that gave me an estimate, he was extremely knowledgeable and patient. He too also answered all of my questions. I enjoyed working with him as well.

Unfortunately I am terrible with names and can’t remember either of them but I wanted it to be known the great service I received.

I appreciate the great experience your company gave me. I look forward to working with your company in the future and will recommend you to my peers in the community.
