Client Testimonials

Prime Mechanical has repeatedly proved themselves to be that dependable partner to Paramount Global (formerly Viacom). Not a vendor providing a service, but a true partner in ensuring their clients receive top tier service and support.

In our 30+ year association with Prime Mechanical I have found few that could measure up to the level of expertise, workmanship, service, and professionalism as both an HVAC Maintenance service provider and installation contractor.

The level of service does not begin and end with the field service mechanics, unlike some “HVAC maintenance” providers, Prime Mechanical’s management is extremely involved in the day to day challenges that may arise with a piece of equipment regardless of the size of the client’s equipment list, supporting their mechanics in the field.

Pride in one’s work is a virtue lacking in some disciplines, but it is in great abundance with Prime Mechanical.

Prime Mechanical has long held a position of respect with Paramount Global

Ruben Rivera, VP Facilities OperationsParamount Global

It is with great enthusiasm that I am writing to recommend the services of Prime Mechanical Systems, Inc.

As a Facilities Manager with nearly 20 years in the field, I have worked with multiple HVAC contractors, and I can confidently say that Prime Mechanical is the best in the business. Their office staff and service department are very responsive and each of their technicians are friendly and knowledgeable.

Prime Mechanical has been an integral part of our operation for over a decade. I am more than happy to recommend them for all of your HVAC needs and am fully confident that your experiences with them will be as positive as mine.

Brandon Candal, Director, Facilities Engineering New York Public Radio

I would like to take this opportunity to provide a personal account of my extensive experience as a project management consultant working with the highly talented staff at Prime Mechanical, my “Go To” HVAC contractor. Their dedication to excellence and professionalism as a collaborative, intuitive and proactive top-tier, NYC-based HVAC firm, both for new projects and preventative maintenance, make them the right choice for any tenant, landlord or developer.

Over my many years working on a broad range of projects with Prime, I have always been impressed with their ability to assess the often complex field conditions, analyze the MEP construction documents and present a myriad of alternate design recommendations that enhance the current mechanical design and reduce budget expenditures. Their practical approach is layered with a detailed perspective that draws on their understanding of mechanical design principals as well as the daily operation and future maintenance of key mechanical equipment components and their associated support equipment.

I hope that the above helps any prospective client to work with Prime Mechanical. Life is so much easier when they are involved. There is security in knowledge, and Prime brings this to every challenge they meet.

Evan Schneider, PresidentProject Control Group, Inc.

I have known and worked closely with Richard Lambert and his company Prime Mechanical for well over 25 years and it is my great pleasure to offer this letter of recommendation.

As the CEO of a consulting engineering firm who looks for a partner who can take our plans and specifications and make it a reality, maintaining our intent and vision, I can say whole heartedly that Prime Mechanical fits the bill and we are delighted when we have a chance to work together.

I have always found them to be professional, timely, knowledgeable, detailed, and creative, when necessary, in order to produce sometimes the most complicated of assignments and challenging schedules.

I can honestly say they are one of our go-to contractors.

Michael Gerazounis, P.E., Managing Principal and CEOMG Engineering D.P.C.

Over the past 15+ years, I’ve had the privilege of working with Prime Mechanical across hundreds of projects in multiple leadership roles throughout my career. In every chapter, Prime has been my go-to HVAC partner. Not for the easy work, but for the most complex, high-pressure, technically demanding projects.

There’s a reason for that. When a job requires precision, deep expertise, and accountability at the highest level, I call Prime. Rich and his team consistently step into complicated conditions, tight schedules, and challenging design constraints and deliver. They don’t make excuses. They solve problems. They collaborate. And they stand behind their work.

What separates Prime isn’t just technical capability, it’s leadership. Rich leads with integrity, transparency, and a genuine ownership mentality. His team treats every project as if it were their own, and that mindset shows in the results.

What excites me most is seeing Prime evolve through the Prime 2.0 initiative. Growth, reinvestment, and continuous improvement are signs of a company that refuses to stay stagnant. After 15+ years of performance, they’re still raising the bar, and that speaks volumes about their long-term vision and commitment to excellence.

Over 100+ projects, Prime has proven to be a trusted partner, a problem solver, and a company I recommend without hesitation. If you want a mechanical contractor who embraces the hard jobs and consistently outperforms, Prime Mechanical is that firm.

Proud to have worked alongside you for all these years, and looking forward to many more.
