24/7 Emergency Commercial HVAC Service

Northern Weathermakers serves commercial and industrial facilities in Chicagoland. For urgent heating, cooling or building controls problems, call 847.498.4590 — nights, weekends and holidays.

Tell the service team where the building is, which equipment is affected, and what has changed. Have any displayed alarm, equipment model and recent service information ready if available. The team will confirm the next steps; a web inquiry is not a dispatch confirmation.

Commercial equipment and service planning

Our services include rooftop units, boilers, chillers, building automation and related commercial equipment. For planned work, explore service and maintenance, chiller and boiler plant service, rooftop repair or replacement, and Maintenance Agreements.

Emergency service questions

Is the line really answered 24/7?

Call 847.498.4590 for commercial HVAC emergencies, including nights, weekends and holidays. Describe the problem and location so the service team can confirm the next steps. Calling or submitting an inquiry does not guarantee an arrival time.

What's considered an emergency?

A loss of heating or cooling, a rooftop unit outage, a chiller fault or a controls problem can disrupt building operations. Call to discuss an urgent commercial HVAC problem. For immediate danger, follow your building emergency procedures and contact emergency services.

Do you work on equipment you didn’t install?

Yes. We're manufacturer-independent. Our technicians service Siemens, Johnson Controls, Trane, ABB, Carrier, and Honeywell.

What systems do you cover?

Rooftop units, boilers and heating, chillers and cooling, and building automation and controls. We also service related commercial equipment including pumps, VFDs, make-up air, exhaust and refrigeration.

Do I need to be an existing customer?

No. New commercial customers can call to discuss their building, equipment and service needs.

What if it’s not actually an emergency?

For a routine inquiry, use the contact page or the callback form when available. A request is not a confirmed appointment. For urgent service, call 847.498.4590.
