ADRIUM Service Solutions

ADRIUM Service Solutions is a family-owned and owner-led heating, ventilation, and air conditioning (HVAC) contractor based in San Ramon, California. The company was founded in 2021 by Andrew Kuznetsov, who passed the California Contractor License exam himself and holds CSLB license #1136642. ADRIUM's HVAC-focused arm does business as Bay Area HVAC Service, serving homeowners and small commercial clients across the Tri-Valley — including Dublin, Pleasanton, Livermore, San Ramon, and Danville — and a total of 56 Bay Area cities. The company also has roots in appliance repair and commercial coffee equipment repair, reflecting its founder's start in the appliance trade. ADRIUM positions itself as "brand-honest" and transparent: it provides written estimates before any work begins, offers a $99 on-site diagnostic that is credited toward the repair, and states that it does not sell systems customers do not need. Its service menu covers AC repair, furnace repair, heat pump installation and service, ductless mini-split systems, full HVAC installation, maintenance plans, and indoor air quality assessments. The company is factory-trained on Daikin (founder Andrew Kuznetsov completed Daikin factory training in Houston in 2025) and is listed on Goodman's official dealer locator. It services more than fourteen brands, including Carrier, Lennox, Trane, Mitsubishi, and Bosch. For new installations, ADRIUM offers a 10-year parts warranty and a labor warranty of 2 years standard, extendable to 10 years with its maintenance plan. It also handles rebate paperwork with programs such as BayREN, MCE, PG&E, and manufacturer rebates. The company operates with a small, consistent crew of four — two technicians and two installers — under its own insurance and license. It emphasizes owner accountability: the founder is in the field, while his wife handles the back office. ADRIUM holds EPA Section 608 Universal certification and a BBB A+ rating, and reports over 600 reviews. It serves both residential and light commercial customers, offering B2B priority service with NET-30 invoicing for real estate professionals and property managers. The company's website is bayareahvacservice.com, and it can be reached at (925) 999-4095, with service hours from 7 AM to 7 PM, seven days a week, and no overtime charges.

ADRIUM Service Solutions was founded in 2021 by Andrew Kuznetsov in San Ramon, California. Kuznetsov, born in Ukraine and having spent most of his adult life in Russia, arrived in California in 2019 as a political refugee with his wife. They came to the Bay Area with five thousand dollars and no contacts. Kuznetsov's father had been an engineer in industrial safety at thermal power stations, and those engineering roots drew him toward trades that work with real systems. He began with appliance repair, a trade he could learn quickly to pay rent. Within a year, he developed a strong understanding of sealed refrigeration — compressors, refrigerant pressures, and the physics of heat exchange. This led him into air conditioning and then into HVAC. In 2021, Kuznetsov founded ADRIUM Service Solutions and passed the California Contractor License exam himself, without buying or transferring a license. The company's HVAC-focused arm operates as Bay Area HVAC Service. In 2025, Kuznetsov completed Daikin factory training in Houston, Texas, and the company is also listed on Goodman's official Find a Dealer locator. ADRIUM is family-run: Kuznetsov's wife handles the back office, while he works in the field. The company maintains a small, consistent crew of four — two technicians and two installers — operating under its own insurance and license (CSLB #1136642). ADRIUM serves homeowners and small commercial clients across 56 Bay Area cities, with a focus on the Tri-Valley region including Dublin, Pleasanton, Livermore, San Ramon, and Danville. The company offers a range of HVAC services: AC repair, furnace repair, heat pump installation and service, ductless mini-split installation, full HVAC installation, maintenance plans, and indoor air quality assessments. It also provides B2B priority service for real estate professionals and property managers, with NET-30 invoicing and owner-direct contact. ADRIUM holds EPA Section 608 Universal certification and a BBB A+ rating, and reports over 600 reviews. The company emphasizes transparency: a $99 on-site diagnostic credited toward repair, written estimates before work begins, and a policy of not selling systems customers do not need. It is factory-trained on Daikin and services fourteen-plus brands including Carrier, Lennox, Trane, Mitsubishi, and Bosch. For new installations, it offers a 10-year parts warranty and a labor warranty of 2 years standard, extendable to 10 years with its maintenance plan. The company also assists with rebate paperwork for programs such as BayREN, MCE, PG&E, and manufacturer rebates.
