Rooftop unit running, but your business has no heat?

Rescuetek provides commercial HVAC service for Chicagoland properties. We assess the reported heating problem in the context of the installed equipment and building controls.

If the building has several units, share the affected unit identifier when it is already available in your records. Tell us whether the unit does not start, runs without useful heat, or shuts down repeatedly.

Include any building-management contact, tenant-access requirements and known roof-access arrangements. Staff should not climb onto the roof or open equipment to gather details for the booking.

The next step should follow the findings and explain what work is proposed. Access, equipment condition and parts availability can affect the repair plan; booking a visit is not a guarantee of a particular completion time. If the complaint also involves air extraction or a separate shop heater, see commercial ventilation service or unit-heater repair.

Contact Rescuetek or call (847) 305-4770. Share the site address and business impact. For a gas odor or CO alarm, follow evacuation and emergency-response procedures first; an HVAC appointment is not emergency clearance.
