A breeze so far!Everything about Smith Thompson has been a breeze so far! The tech that installed our system was extremely knowledgeable- we had a lot of questions. He was not pushy with products, just presented our options.. which I appreciated a lot. I have enjoyed the service & would definitely recommend. You can’t be the prices either!
Simple, easy, and straight forward.We just moved into our new home... and dealt with many different companies and their representatives. So far, our experience with Smith Thomson is the best. They made it simple, easy, and straight forward -- just the way we expected. And best of all their price is very reasonable and affordable. Highly recommended. Wish to see more businesses like Smith Thompson...
