Services
HVAC Installation
We design and install large-scale heating, ventilation, and air conditioning systems for commercial and industrial facilities. Our expertise includes high-efficiency chillers, cooling towers, and variable frequency drives that optimize energy consumption. Projects integrate seamlessly with building infrastructure while meeting strict regulatory requirements for healthcare and critical facilities.
Refrigeration Upgrades
Our team modernizes refrigeration systems for food processing plants, cold storage warehouses, and retail environments. We specialize in transitioning from R-22 to environmentally friendly refrigerants while maintaining operational continuity. Projects incorporate advanced glycol piping systems and energy recovery solutions for maximum efficiency.
Cogeneration Systems
We implement combined heat and power (CHP) systems that generate electricity while capturing waste heat for building heating or cooling. These systems reduce grid dependency and lower carbon footprints for hospitals, universities, and manufacturing facilities through customized natural gas turbine installations.
Emergency Maintenance
Our 24/7 emergency service addresses critical HVAC/R system failures with rapid response teams available year-round. We minimize downtime through preventative maintenance programs that include scheduled inspections, component testing, and system optimization for commercial clients.
Process Piping
We install and service complex piping systems for industrial applications, including medical gas distribution, hydronic heating, and specialty chemical transport. Our ASME-certified welders ensure leak-tight connections for high-pressure systems, with in-house fabrication capabilities reducing field installation time.
