How we got here

My wife and I came to California in 2019 as political refugees. I was born in Ukraine, spent most of my adult life in Russia, and left when principled opposition to the regime was no longer safe for our family. That was three years before the full-scale invasion. We were people who refused to compromise, not people fleeing active war. We were in our early thirties, arriving in the Bay Area with five thousand dollars and no contacts.

My father had been an engineer in industrial safety at thermal power stations back home, and those engineering roots are what pulled me toward trades that work with real systems. I started with appliance repair: a trade I could learn quickly, a way to pay rent, and, as it turned out, the foundation of everything that came after.

Within a year, sealed refrigeration clicked for me. Compressors, refrigerant pressures, the physics of heat exchange. Refrigeration took me into air conditioning, AC took me into HVAC. I founded ADRIUM Service Solutions in 2021 and passed the California Contractor License exam myself. I did not buy a license or transfer one. I studied, sat for it, passed. In 2025 I earned factory training at the Daikin/Goodman plant in Houston, a 16,000-employee Texas facility that stands behind every heat pump we install.

Bay Area HVAC Service is the HVAC-focused arm of ADRIUM. We are family-run: my wife handles the back office, I am in the field. We work with a small, consistent crew of four (two technicians and two installers) under our insurance and our license. When something goes wrong, the responsibility lands on me, not a call center.

What we stand for

Honest pricing, written estimates, no pressure. HVAC has earned a bad reputation: technicians quoting fifteen thousand dollars to replace a system when the real problem is a two-hundred-dollar fix. We do not work that way. A written estimate before any work begins. If the right answer is a repair instead of a replacement, the estimate says so.

Owner-accountable, every job. For installations and complex service quotes, I meet you personally. For routine service calls, our trained technicians arrive, but every invoice carries my license number, and every estimate I review before it reaches you. One person responsible. No passing of blame.

Second opinions welcome. If another company has quoted you thousands to replace a working system, call us. We charge $75 to come show you what is actually going on, and we credit that diagnostic toward any repair over two hundred dollars. We like breaking bad templates.

Performance logs, like a doctor. We record your system's readings on every visit. Static pressures, refrigerant subcooling, capacitor microfarads, blower current. Next year, we compare. You get early warning on problems before they become summer emergencies, and you get a written maintenance history that follows the home if you sell.

I don't try to sell anyone a system. I give you options. If the right answer is a repair instead of a replacement, I'll tell you. Second opinions are welcome here. We like breaking bad templates.

What you can verify

"Family-owned" is easy to put on a website. The harder part is showing the receipts. Everything here is checkable in a public registry: the California state contractor's database, the EPA refrigerant registry, the Better Business Bureau, Wikidata. If something on this page is wrong, the registries will tell on us before we do.

Our California contractor's license is CSLB #1136642, in good standing since 2021. EPA Section 608 universal certification on file, #1279674151528. HC(A3) & HFO(A2L) Certified Technician (Mainstream Engineering, cert #H43E9118EC832MMM0), trained on the new low-GWP A2L refrigerants now shipping in heat pumps and AC systems. Better Business Bureau accreditation, A+. Daikin Comfort Pro factory training, Houston 2025. Mitsubishi Electric factory training: M- and P-Series Essentials (May 2026) and Advanced M- and P-Series Service at the Los Angeles training center (June 2026). MCE Clean Energy participating contractor for heat-pump incentives.

The team, and the work

The team is small on purpose. Four people: two service technicians, two installers, plus my wife on scheduling and invoicing, and me on estimates. All four field people are consistent (not rotating strangers) working under ADRIUM's license, insurance, and training standards. When the work scales beyond what we can do well, we decline the job rather than dilute the standard.

Tech Aid for Refugees

The nonprofit half of our work began in September 2023, after we had been on our feet long enough to give back to families who arrived the way we did: primarily Ukrainian, primarily after the invasion. We collect, repair, and deliver household appliances: refrigerators, ranges, washers, dryers. The IRS recognizes the organization as a 501(c)(3) under EIN 93-3707362; the full story is on the community page.

A neighbor who gave us a mattress when we first arrived told me: "when you're on your feet, remember people in the same place." That became how we measure our years here.
