Walnut Creek is a city in Contra Costa County in the East Bay Region. It serves as a hub for neighboring cities because of its location at the junction of the highways from Sacramento and San Jose, and San Francisco/Oakland and its accessibility to BART. Walnut Creek’s warm summer Mediterranean climate is typical of California’s interior valleys. In summer, high pressure leads to near unbroken sunshine and virtually no precipitation, so having a reliable company for AC repair is important. Days can be cool in the winter, and furnace maintenance is important as well.

Going over options to add a single zone mini split system to a far bedroom that does not get adequate heating & cooling. This beautiful home is located in Walnut Creek right outside of the Rossmoor Community, what a great neighborhood! This client is hoping to put his spare room on its own zone for guests and the mini split idea is the way to go! Talked to client about options and recommendations, as well as financing options. Thanks for choosing Certified Heating & Air Conditioning!
