What We Do

Expert building engineering — whenever you need it.

❄️

HVAC Supervision & Troubleshooting

From rooftop units to chiller plants, we diagnose issues, supervise repairs, and keep your climate systems running. Available after hours when problems don't wait until Monday.

🚨

Emergency Response

When a system fails at 2 AM or tenants lose cooling during a heat wave, we're there. Rapid dispatch, expert diagnosis, and clear communication with your team until it's resolved.

⚡

Generator Testing & Compliance

Weekly emergency power generator testing aligned with NFPA standards. We run the tests, document results, and flag issues before they become emergencies.

🏗️

Capital Project Management

Equipment replacements, system upgrades, energy efficiency retrofits. We manage the project from design through commissioning so you don't have to become an engineer.

🔧

Preventive Maintenance Oversight

We supervise your maintenance vendors, verify work quality, and catch issues before they cascade. Someone with engineering expertise watching over your building, not just checking boxes.

🌙

After-Hours Building Engineering

Weekends, holidays, overnight — we cover the hours when most engineers are unreachable. Your tenants don't care what day it is, and neither do building systems.
