Five Star HVAC Service

Five Star HVAC Service operates as a heating and cooling contractor serving Sacramento and the broader East Bay region, including Concord, Walnut Creek, and Pleasant Hill. The company holds a 5.0-star rating across two customer reviews, reflecting consistent service quality for residential clients. Owner Martin Santillan leads service calls and has built relationships with local real estate professionals who recommend his work for both repair and installation projects.

The contractor distinguishes itself through personalized attention and transparent communication. Technicians take time to explain diagnostic findings to homeowners rather than proceeding with repairs without clarification. This approach, combined with responsiveness during urgent situations, has generated strong word-of-mouth referrals from property managers and real estate brokers across Contra Costa County.

Jenny Ramos experienced this commitment firsthand when her AC failed during a Sacramento heat wave. Five Star responded quickly, diagnosed the issue, and restored operation the same day. The technician walked her through the problem and the solution, leaving her system performing better than before. Real estate professional Monica Fosbery has relied on Martin Santillan for multiple properties throughout Concord, Walnut Creek, and surrounding East Bay cities, praising his reliability during time-sensitive transactions and ongoing property maintenance needs.
