Rooftop Unit
(RTU) Replacement
When a commercial rooftop unit reaches the end of its life, Lolich Heating & Cooling handles the full replacement — from site assessment and equipment specification through installation and commissioning. Clear scopes, straightforward pricing, and minimal disruption to your tenants and operations.
How We Handle an RTU Replacement
Site Assessment
We assess your existing RTU, curb, ductwork connections, electrical, and roof access to build an accurate scope before you receive a number.
Equipment Specification
We specify the right replacement unit for your application — matching tonnage, configuration, and efficiency requirements.
Bid & Approval
You receive a clear, itemized bid covering equipment, labor, crane or lift if required, and any curb adapters or ductwork modifications needed.
Scheduled Replacement
We coordinate the replacement to minimize disruption to your tenants and building operations, including after-hours scheduling when needed.
Startup & Commissioning
Every replacement is commissioned and tested before we leave the job. We document the install and walk you through the completed work.
RTU Applications We Handle
Packaged rooftop units are the workhorses of commercial HVAC. When they fail or reach end of life, we assess the full scope — including curb compatibility, electrical requirements, and ductwork — before giving you a number.
RTU Failing or at End of Life?
Don't wait for a complete failure in the middle of a tenant's lease. Schedule a site walk and we'll assess your equipment and put together a replacement plan.
