How far is Hayward from your base in San Ramon?

About 25 minutes on 580 over the hill. Hayward sits in the middle of my Inner East Bay loop with Castro Valley, San Leandro, and Union City, so I am nearby most days and same-day visits are realistic. We run 7 days a week.

I manage rental properties in Hayward. Can you work directly with tenants?

Yes. We coordinate access with the tenant, you get the written diagnostic and quote before any work is approved, and the invoice documents everything for your file. Approval stays with you, not the tenant.

Is there a warranty on the repair?

One year, parts and labor, on the repair we perform. You also get a written quote up front, and the $75 diagnostic fee disappears if you go ahead with the work.

Sub-Zero in Hayward

Sub-Zero in Hayward kitchens.

Hayward gives me the widest spread of Sub-Zero work of any city on my route. Up in the Hayward hills there are estate kitchens running 611s and 48 inch built-ins that have been in place for two decades. Down in the flats, the ADU and rental boom has put a surprising number of UC-24 undercounter units and integrated columns into small spaces, and those get worked hard by tenants.

ADRIUM Service Solutions is owner-run by Andrew Kuznetsov out of San Ramon, about 25 minutes away on 580. I am EPA Section 608 Universal certified, licensed under CSLB #1136642, and I quote everything in writing before touching a wrench. The $75 diagnostic is waived when you approve the repair, repairs carry a one year parts and labor warranty, and we schedule 7 days a week.

For landlords and property managers in Hayward, I keep the paper trail clean: written diagnosis, written quote, and an invoice that documents the repair for your records.

What the work looks like

A built-in sealed-system leak repair.

Nitrogen pressure and a soap-bubble test on a built-in fridge line set. We map every leak source before we braze.

The corroded copper up close. After fifteen-plus years this is why a real fix rebuilds the sealed run, so you do not pay the labor twice.

ADRIUM technician brazing a copper refrigerant line onto a compressor with a torch during a sealed-system repair — Brazing a new line onto the compressor during the same kind of sealed-system repair. Recover, braze, evacuate, and recharge: the real fix, done as one complete job.

Common repairs we do

What we close on the truck.

611 losing the fresh food side. The 611 over-under is common in hills homes, and its known weak point at this age is refrigerant loss on the fresh food circuit. Milk goes borderline while the freezer stays rock solid. I confirm with gauge readings and a leak search, then do the sealed system repair and recharge myself under my 608 Universal certification.
UC-24 undercounter icing up in ADUs. Undercounter Sub-Zeros in ADUs and in-law units get their door opened constantly and often sit in tight alcoves with poor airflow. Frost builds on the evaporator, cooling drops, and tenants report it late. I clear the frost, test the defrost circuit, and check the installation clearances, because a unit starved for air will just fail again.
Torn gaskets and door abuse in rental kitchens. Rental units show gasket damage years before owner-occupied ones. A torn or compressed magnetic gasket lets humid air in, the evaporator ices over, and energy use climbs. New gaskets and a door alignment are a same-visit fix on most models, and it is one of the cheapest repairs that actually extends a Sub-Zero's life.

Sub-Zero 501F Sealed System Rebuild and Restoration

A 1991 Sub-Zero 501F built-in that stopped holding temperature. A refrigerant leak had emptied the sealed system, on a unit with a rough history: a prior compressor swap, burn marks from a past fire, and a rusted cabinet.
