Designers, builders, and refrigeration specialists for the finest private wine cellars in Southern California. Two decades. One discipline.
We are authorized dealers for every major manufacturer of wine cellar refrigeration — and we are deliberately agnostic. The right system is the one that fits the room, the wine, and the silence you expect from it.
Commercial-grade splits
Our most-specified line. Modular split systems for residential cellars where silence and longevity are non-negotiable.
Self-contained & ducted
A workhorse of climate control. Compact through-wall and ducted options for both new builds and retrofits.
Through-wall & split
Industrial precision with humidity control engineered for long-aging collections in California's variable climate.
SC Pro Series
The standard for whisper-quiet operation in adjacent living spaces. Specified often, installed exactly.
Through-the-wall
A trusted line for smaller cellars and wine cabinet retrofits where compact reliability matters most.
Specialty units
For uncommon installations — ductable, ceiling-mounted, and split configurations tailored to architectural constraints.
We don't subcontract the cellar to a builder and the cooling to an HVAC company. We design the room, build it, condition it, and quietly maintain it for the life of your collection.
It is the difference between a wine room that works and a wine room that endures.
About The Studio →From the first sketch to the quarterly service call years later — your cellar is built and protected by one team, one phone number, one standard of care.
An on-site visit with a cellar designer. We assess the space, your collection, and the architectural intent before drawing a single line.
Vapor barriers, custom racking, glass walls, doors, and millwork — built by craftspeople who only build wine cellars.
The right system for the room — split, ducted, ceiling-mounted, or self-contained. Specified, installed, and commissioned in-house.
Quarterly maintenance, emergency service, and refrigerant work — performed by the same technicians who built the room.
A great cellar lives or dies by two numbers — temperature and humidity. We design and commission every system to hold them precisely, silently, and without drift, for the entire life of your collection.
A waterfall-style residential wine room with custom wooden racking, vapor sealing, and a whisper-quiet split refrigeration system — designed in collaboration with the homeowner's architect and finished to gallery standard.
Explore The Project →Out of all our providers, Mario and M&M Cellars are number one.
Mario showed up to install the new system. His experience really showed and allowed for a smooth installation. He was respectful of our home and kept a clean work environment.
My wine storage cooler is unique and requires excellent knowledge to maintain it properly. M&M has always been responsive — professional, knowledgeable, and helpful.
After a bad experience with another refrigeration company, I was referred to M&M. Mario fixed my wine room compressor without selling me anything. Amazing service by really good and honest guys.
