Commercial HVAC Installation

Built to Perform. Designed for Demanding Facilities.

CRS Mechanical delivers turnkey commercial HVAC installations across New Hampshire. Whether you're outfitting a new build, upgrading an outdated system, or expanding infrastructure, our EPA-certified team designs and installs systems that meet code, perform under pressure, and are tailored to your exact needs. We work directly with facility managers, project engineers, and property owners to deliver on time—and get it right the first time.

Industries We Serve:

  • From high-rises to multi-tenant office parks, we design and maintain HVAC systems that provide consistent comfort, clean air, and quiet operation. Our work supports energy efficiency goals, and ensures seamless coordination with property managers, tenants, and contractors during both construction and retrofits.

  • We specialize in HVAC and refrigeration systems for hospitals, surgical centers, and medical clinics, where air quality, redundancy, and code compliance aren’t optional—they’re mission-critical. Our team follows ASHRAE healthcare standards and works within sensitive timelines to avoid disruption to patient care and facility operations.

  • We help K-12 schools, colleges, and universities upgrade and maintain mechanical systems that provide safe, healthy, and cost-effective learning environments. From retrofits in century-old buildings to new installations in state-of-the-art facilities, our solutions meet today’s energy standards and tomorrow’s demands.

  • In industrial facilities, HVAC isn’t about comfort—it’s about control. We design and service systems that manage heat loads, process cooling, ventilation, and indoor air quality to protect people, product, and productivity. Our team understands the safety protocols and production schedules that define these fast-paced environments.

  • We engineer mission-critical cooling and environmental control systems for data centers of all sizes. Our team ensures continuous uptime, redundancy planning, and tight temperature/humidity regulation to protect servers, reduce energy waste, and support 24/7 operations. When failure isn’t an option, CRS is the partner you want on call.

  • CRS Mechanical supports municipal buildings, courthouses, fire stations, and other public infrastructure with compliant, efficient HVAC and mechanical systems. We understand the procurement process, prevailing wage requirements, and the long-term demands of public-sector projects—and we deliver with integrity.

Let’s design an HVAC system that works as hard as your building.
