Services
HVAC Installation
We provide complete HVAC system installations for commercial properties, including centrifugal chillers up to 1,000 tons and variable frequency drives. Our technicians ensure proper system integration with building automation controls while maintaining manufacturer certifications for optimal performance. With over 30 years of experience, we deliver energy-efficient solutions that meet ASHRAE standards and local mechanical codes.
Chiller Retrofitting
Our chiller retrofit services modernize aging HVAC systems to improve energy efficiency and environmental compliance. We perform comprehensive site analyses to determine optimal retrofit strategies, including component replacement and control system upgrades. By upgrading existing systems rather than full replacements, we help clients achieve significant cost savings while extending equipment lifespan and improving cooling capacity.
Emergency Repairs
We offer 24/7 emergency HVAC repair services to minimize operational downtime for critical facilities. Our factory-certified technicians respond promptly to system failures, performing urgent repairs on boilers, chillers, and climate control systems. With mobile service units stocked with specialized parts, we restore functionality to commercial HVAC systems in airports, hospitals, and industrial facilities across the region.
Preventative Maintenance
Our customized maintenance programs include quarterly system inspections, oil analysis, and component cleaning to prevent unexpected failures. We use predictive analysis tools to monitor system performance trends and schedule proactive repairs. Regular maintenance extends equipment lifespan, improves energy efficiency, and maintains manufacturer warranty compliance for commercial HVAC systems.
Energy Management
We implement energy management systems that optimize HVAC performance while reducing operational costs. Our solutions include building automation integration, load management controls, and energy usage reporting. By analyzing system data and implementing efficiency upgrades, we help commercial clients achieve significant energy savings while maintaining optimal climate control for their facilities.
