3 new units. Best service we could possibly have. Completely blown away by the prep before and after with red carpets, plastic and the extra care taken to make sure we were comfortable. The AC installs were a major deal for us and George and his team kept us to date the entire time. We felt very fortunate to have the kind of quality work on something as scary as replacing all three units. Could not have asked for better service. Christian Brothers has earned our business for any home service we need.
