We have been Bay Area customers for more than 10 years. We purchased our unit from them with a 10 year warranty, which we renewed recently. The smaller upper unit was replaced 9 years ago. The service has always been responsive - even following a hurricane a few years back. Typical repair time 1-2 days. Always a pleasant experience. We were referred to them by a friend and we referred them to our friend. EVERYONE IS VERY HAPPY - still. We were just talking about them yesterday - the day before service. HIGHLY RECOMMEND!!!
