Around-the-clock emergency commercial and industrial HVAC, chiller, boiler, and refrigeration repair across Chicagoland, Northern Illinois & Indiana.
What this covers
Scope
- We dispatch commercial and industrial HVAC technicians around the clock for urgent breakdowns across Chicagoland, Northern Illinois & Indiana.
- We troubleshoot and repair tripped air-cooled and water-cooled chillers, booster chilling loops, and process cooling systems halting production.
- We restore failed boilers, locked-out burners, and down rooftop units during severe heating and cooling weather.
- We respond to commercial and industrial refrigeration failures, BAS control lockouts, and vent hood and ductwork exhaust outages.
Problems we solve
- Unexpected primary chiller or booster chilling faults halt industrial production lines and destabilize process temperatures.
- Winter boiler lockouts and rooftop heating failures expose building piping, sprinkler lines, and occupied spaces to freeze damage.
- Compressor failures, defrost faults, and refrigerant leaks threaten temperature-sensitive inventory in cold storage and process refrigeration.
- Sudden cooling or BAS control outages make occupied offices, commercial buildings, and plant floors untenable during summer heat.

Planned work
Once emergency stabilization restores safe operation, we scope permanent component replacements or system retrofits around your operating calendar.

Preventive maintenance contracts reduce repeat after-hours callouts on stabilized equipment through regular seasonal inspection and cleaning.
In the shop
When an emergency repair requires a custom ductwork transition, welded bracket, or fabricated cooling assembly, the part is built in our own shop.
