HVAC contractor in Alameda County, CA

Yes. Many pre-1950 homes in Oakland and Berkeley were built with radiant heat or wall furnaces and have no existing duct system. We assess the home's layout and identify the best routing for supply and return ducts, often using high-velocity mini-duct systems or ductless mini-splits when traditional ductwork is not practical. The goal is a system that fits the home's structure without major demolition.

Livermore and Pleasanton sit in the Tri-Valley, where summer temperatures regularly reach the mid-to-upper 90s and occasionally exceed 100°F. Systems in those cities run at high load for extended periods, which stresses compressors and electrical components. Many of the homes there were built in the 1980s and 1990s, meaning their original systems are now at or past the end of a typical service life.

Yes. Oakland's industrial and warehouse corridor along the waterfront and the Fruitvale and Coliseum areas includes large buildings with rooftop package units, split systems, and in some cases older make-up air units. We service and install commercial HVAC for those property types, including preventive maintenance contracts for building owners who need scheduled service.

Homes from that era in Hayward and San Leandro often have sheet metal ductwork that has accumulated decades of dust, and in some cases the original duct insulation has deteriorated inside the plenum. A duct cleaning removes that buildup from supply and return lines, which improves airflow and reduces the amount of debris the air handler pulls through the system. We inspect for duct leaks at the same time.

Yes. We service commercial refrigeration for restaurants, grocery stores, and food service businesses throughout Alameda County, including Oakland and Hayward, where the food service industry is concentrated. Commercial refrigeration maintenance is especially important in summer, when high ambient temperatures raise condensing pressure and increase the risk of compressor failure.
