Contra Costa Heating & Air Conditioning

Contra Costa Heating & Air Conditioning has been keeping Pleasanton-area homes comfortable for years, earning a 4.1-star average from 94 customer reviews. Based in the heart of Contra Costa County, this contractor serves Pleasanton alongside nearby communities including Dublin, Livermore, and Walnut Creek. The team handles residential heating and cooling projects ranging from routine maintenance to full system replacements, earning recognition for steady workmanship across the Bay Area foothills.

This contractor has built a specialty around heat pump technology and ductless mini-split systems, two categories increasingly in demand as Bay Area homeowners seek energy-efficient alternatives to traditional gas furnaces and central air. Heat pumps deliver both heating and cooling in a single unit, while mini-split installations offer targeted climate control without requiring ductwork. The company provides upfront estimates and walks customers through equipment options rather than steering toward the priciest model, a consultative approach that multiple reviewers specifically noted as refreshing compared to other sales encounters.

Customers who called out technicians by name highlight what distinguishes this crew. Installer Oscan and technician Jairo arrived prepared for an appointment, handled unexpected obstacles during a heat pump installation without frustration, and wrapped up leaving no debris behind. Heating consultant Raji visited a customer's home having already researched the existing gas furnace, electrical setup, and desired location before walking through multiple equipment options with balanced, non-pushy guidance. Setiawan Sulistyono credited the team with a timely winter heater repair, clear explanation of the issue, and a spotless work area upon departure.
