Rooftop Unit Replacement in Tempe, AZ
Rooftop unit replacement means pulling out an existing RTU and installing a new one in its place, including all electrical, refrigerant, and ductwork connections. It's the right call when a unit is beyond economical repair, when parts are no longer available, or when efficiency has dropped far enough to make operating costs unreasonable. A replacement done right should match or exceed the original unit's capacity and fit the existing curb without major structural modifications.

How It Works
Our Process for Rooftop Unit Replacement
- 1
Unit Assessment and Sizing
We verify the replacement unit matches the existing curb dimensions, electrical supply, and tonnage requirements for the space.
- 2
Old Unit Removal
The existing unit is properly disconnected, refrigerant recovered, and the unit removed from the roof without damaging the curb or roof membrane.
- 3
New Unit Installation
The replacement unit is set, connected to existing electrical and ductwork, and refrigerant is charged to manufacturer specifications.
- 4
Startup and Verification
We run the new unit through a complete startup checklist and confirm cooling performance before signing off on the job.
Tempe Context
Why this matters in Tempe
Many Tempe commercial buildings from the 1990s and early 2000s are now on their second or third RTU cycle. Equipment that was installed before current efficiency standards became mandatory is often worth replacing on cost savings alone.
Straight Talk
About pricing & scope
Total cost depends on unit tonnage, crane or lift requirements for rooftop access, and whether the existing electrical disconnect or ductwork connections need updating to meet current code.
