Dick Barrett, Apr 11, 2023

Always a good experience with S&Z. Great communications, service, and results. For over 25 years we have had installs (heat and ac); maintenance (scheduled and unscheduled); and, work done that our aging home required in order to ensure a quality outcome. Never once have we been uncomfortable or dissatisfied with this firm’s team of skilled people who go out of their way to satisfy the customer. It sounds corny but they do make us feel like family. I say that knowing there’s nothing special about us!
