Rooftop Units & Packaged Systems
Most Chicago commercial buildings rely on rooftop units (RTUs) for heating and cooling. These packaged systems take a beating from the region's weather, and neglected units fail at the worst times. We repair, replace, and maintain RTUs of all sizes, handling the access and safety logistics that rooftop work demands.
For buildings with split systems, packaged units, or specialized equipment, we provide the same reliable service — sized and configured for the space, the load, and how your business actually uses it.
- RTU repair, replacement, and scheduled maintenance
- Packaged and split commercial systems
- Economizers, controls, and thermostats
- Restaurant make-up air and kitchen exhaust
- Warehouse and industrial space conditioning
Maintenance Programs That Protect Uptime
Unplanned downtime is expensive — in lost sales, uncomfortable customers, and emergency repair premiums. Our commercial maintenance programs catch developing problems, keep equipment efficient, and give you documented service history for compliance and budgeting. For property managers, we coordinate consistent service across every location so nothing falls through the cracks.

What Affects the Cost
Commercial HVAC is quoted per project based on equipment, scope, and access. Here's what shapes the cost.
Equipment size and type
RTU tonnage, packaged versus split systems, and specialized equipment all affect parts and labor.
Access and logistics
Rooftop access, cranes for large units, tenant coordination, and after-hours work factor into the total.
Scope of work
A repair, a full replacement, and a new build-out are very different investments.
Maintenance agreement
Contract customers receive priority service and pricing that lowers total cost of ownership.
