Steve was excellent! He accessed both a/c units carefully and was able to figure out the problem and solve it. He took time to explain how to maintain units so they perform to their maximum potential. I honestly thought both units had to be replaced and was ready to bite the bullet and replace them, however Steve was honest and said they at least have 4 years left. I feel other companies would have taken advantage of the situation, but not Bay Area conditioning. Thank you for such great service !
