M&M Cellar Systems is a Los Angeles-based wine cellar cooling specialist serving homeowners and commercial clients across Los Angeles and Orange County. With a 4.9-star average from 22 verified reviews, the team focuses exclusively on refrigerated wine storage rather than general HVAC work. This narrow focus means every technician on staff spends their days mastering the unique demands of wine cellar refrigeration, from split system installations in Bel Air residences to commercial cooling units serving boutique hotels in Newport Beach. As an authorized dealer for US Cellar Systems, CellarPro, Wine Guardian, and WhisperKOOL, M&M maintains direct access to manufacturer parts and technical support that independent contractors often cannot match.
What separates M&M from general AC shops is their dedication to a single trade. While most HVAC companies treat wine cooling as a footnote, the technicians here have completed factory certifications on every major cellar refrigeration brand and regularly attend manufacturer training sessions. Their website explicitly promises that they can ship cooling equipment anywhere in the country, making them a resource even for clients outside their California service territory. The team handles everything from initial system selection and design consultation through installation, preventive maintenance, and emergency repairs, giving clients a single point of contact throughout a wine cellar lifecycle.
Customer reviews repeatedly name Mario as the primary technician delivering these results. Eugenia Esgalhado describes working with him over several years on her wine room cooling units, calling him professional and attentive to specific client needs. Bob Knapp hired Mario after a frustrating experience with another contractor on a complex wine cooling installation, noting that Mario explained the technical issues and available options clearly before completing the work successfully. Nancy Dickerson describes having a new cooling system installed in July 2020, where Mario presented several options, explained tradeoffs patiently, and executed the installation cleanly while respecting her home environment.
What Customers Say
All 22 reviewers award 5 stars, with Mario earning specific recognition in four of those reviews for professionalism, technical depth, and patient communication. Customers consistently praise the team's ability to diagnose problems that left previous contractors stumped and to execute clean installations on first attempt.
