About Us


EHMS Mechanical Services maintains, repairs and installs complex mechanical systems for commercial, industrial and institutional markets. Our clients include some of the largest manufacturing, commercial real estate, medical and institutional facilities in the area. We offer a wide range of services that include preventive maintenance agreements, repairs, equipment replacement, energy reduction assessments, retrofits, service and installation projects.

Our success can be directly attributed to our dedicated team. We’re fortunate to have the most talented and highly trained union service technicians, pipe fitters and sheet metal workers in the business. We work hard to maintain a culture that fosters innovation, rewards success, reinforces safety and maximizes the collective knowledge of our team. We never compromise on the quality of our work, or the unmatched level of service, we provide each and every time.


EHMS’ roots in the local HVAC market can be traced back more than 30 years to the V.A. Smith Company, one of the area’s oldest and most respected mechanical contractors. Richard Carlini acquired the service assets in 2014 to form a premier mechanical contractor known as EHMS Mechanical Services, a division of All Mechanical Industries. This union created a unique dynamic where innovation and attention to customer service have led to consistent growth year after year.

EHMS will work tirelessly to be your preferred HVAC service provider, advocate and strategic partner. Our goal is to exceed expectations by safely delivering quality workmanship and excellent customer service. Helping our customers reduce the overall cost of system ownership is where real, long-term value is best measured.
