Three generations of family-owned refrigeration service.

Carney Refrigeration Inc. has been keeping Bay Area businesses cold since 1946 — when refrigeration meant glass-lined boxes, copper tubing, and a service truck stocked with whatever you could fit in it.

Today, we run a tight crew of certified technicians serving everything from neighborhood restaurants to airport lounges and 40,000-square-foot cold-storage warehouses. Same family. Same standards. Modern equipment.

When you call Carney, you get a technician who's seen it before — and an owner who picks up the phone.

The kind of technicians the manufacturers actually train.

Most refrigeration outfits chase the lowest-cost part and call it a day. We do the opposite — investing in factory training, top-tier tools, and the manufacturer relationships that let us go further for our clients than the rest of the field.

— 01 / Factory-Trained

Trained directly by the manufacturers who build the equipment.

Every technician on our crew attends factory training at major manufacturer facilities multiple times a year. We don't learn from YouTube — we learn from the engineers who designed the system.

That depth means faster diagnostics, fewer callbacks, and confidence that the work is done right the first time.

Multiple Factory Visits / Year
— 02 / Industry Relationships

Direct lines to the decision-makers at the manufacturer level.

Decades of attending trade shows and building relationships with manufacturer leadership means we get answers — and a level of support — that the average shop simply can't.

For our clients, that often translates to priority parts access, engineering support on unusual problems, and case-by-case warranty advocacy when it matters most.

Direct Manufacturer Access
— 03 / Best-In-Class Tools

The Inficon D-TEK Pro and other industry-leading equipment.

We invest heavily in the best diagnostic tools on the market — including the Inficon D-TEK Pro, the most sensitive refrigerant leak detector available to the trade.

Better tools find problems faster. Less time chasing leaks means lower bills for you and better outcomes for your equipment.

— 04 / Next-Gen Refrigerants

One of the few shops in the area trained on CO₂ and A2L systems.

The refrigeration industry is shifting fast — natural refrigerants like CO₂ (R-744) and the new low-GWP A2L blends are replacing legacy refrigerants under federal regulations. Most service companies in our area aren't trained to handle them yet.

We are. Our technicians have completed factory training on CO₂ transcritical systems and A2L refrigerant safety — so when the next generation of equipment shows up at your facility, we don't have to refer you elsewhere.

Know what your walk-in is doing — before it fails.

We're certified and fully trained on the Heatcraft intelliGen system — the most comprehensive remote monitoring platform in commercial refrigeration today.

Unlike generic temperature loggers, intelliGen gives our team real-time visibility into the entire system: internal status, alerts, and diagnostics streamed directly to us — and to you — so problems are addressed before your product is at risk.
