Our Story

Sound Refrigeration & Air Conditioning was established in New York, on September 13, 1947. Cosmos Marentis built the business by specializing in HVAC service and installations for the banking industry with special emphasis on computer rooms and trading floors. In 1990, Cosmos retired as President of Sound A/C and was succeeded by Steven Marentis/President, Robert Gulmi/Vice President of Construction, Richard Stankiewicz/Vice President of Service and John Stamm/Director of Operations. Today we continue the trend of doing business with banking and financial institutions in addition to the entertainment, hospital, retail, telecommunications and other industries. In 2017, Steven Marentis retired as President and has been succeeded by Robert Gulmi, who will continue in the tradition of growing and expanding the company as we celebrate our 70th anniversary.

Our office and field staff are vastly experienced in renovations, both Plan and Specification or Design and Install. We can accommodate projects ranging from one room to an entire building, encompassing all HVAC trades. Among our other HVAC specialties are Energy Management, LEED, refurbishment/replacement of existing systems, system design and troubleshooting and maintenance.

We believe that educating and training our personnel is the key to staying ahead of our changing industry. All our project managers and superintendents are continually enrolled in technical industry seminars and NYU Continuing Education programs. Our mechanics are required to maintain not only current licenses but are routinely enrolled in courses and seminars to further enhance their working knowledge. We are authorized dealers for Liebert, Carrier, Trane and York equipment and our service mechanics are routinely updated on servicing information from these and other manufacturers. In addition, all apprentices are enrolled in the Local 638 four year Air Conditioning and Refrigeration Training Program.

Our steamfitting is organized under the name of Infinity Mechanical Inc., which employs 40 to 50 Local 638 Steamfitters and 20 Local 21 Steamfitters.

Our staff has extensive experience with layout and design of HVAC systems for commercial and industrial buildings. We have designed computer facilities, health care facilities, mechanical rooms, retail spaces, tenant alterations and conducted energy surveys. Our CAD & BIM drafting facility meets the needs of our changing industry and enables interface with architects and building management. Our goal is to provide the best possible engineered system, while striving to meet the needs of our clients while recognizing budget constraints.

Sound Refrigeration & Air Conditioning is able to assist clients with analyzing HVAC system deficiencies for practical solutions, while maintaining building standards and codes.
