ELECSYS delivers integrated heating, ventilation, air conditioning, plumbing, and fire protection engineering that keeps facilities safe, comfortable, and code-compliant—especially in live, infrastructure-intensive environments. From utility central plants and specialty ventilation to domestic water, storm, and fire protection systems, we design solutions that work for treatment plants, tunnels, bridges, industrial and municipal facilities, buildings and campuses, and aviation assets. Our team focuses on constructability, phasing, and life safety performance so upgrades can be delivered with minimal downtime and clear paths through local authorities having jurisdiction review and permitting.
Mechanical (HVAC) Engineering

- Central plants with chillers, boilers, heat recovery, and thermal-storage strategies
- Air handling and ventilation systems, including dedicated outdoor air systems, energy recovery, and filtration
- Hydronic, steam, and condenser-water distribution, including variable-flow systems
- Specialty HVAC for process spaces, equipment rooms, and server/telecom rooms
- Equipment replacement, phasing, and temporary services in live facilities
- Energy efficiency measures and electrification
Plumbing Engineering
- Domestic cold and hot water systems, storage, and recirculation
- Sanitary, vent, and storm drainage systems, including roof drainage
- Gas distribution and meter coordination with utilities
- Booster pumps, backflow prevention, and water-treatment systems
- Specialty and process piping (acid waste/neutralization, compressed air)
- Fixture specifications, plumbing code analysis, and permitting support
Fire Protection Engineering
- Fire sprinkler systems: wet, dry, pre-action, and fire-pump sizing
- Special-hazard systems (clean agent, foam, etc.) and detection interfaces
- Hydraulic calculations, piping layouts, and seismic bracing details
- Fire alarm interface criteria and life safety sequence coordination
- Code analysis, local authority coordination, and permitting for fire and life safety
