Rooftop Unit Repair in Tempe, AZ
Rooftop unit repair covers any service call where an RTU is failing to cool, short-cycling, tripping breakers, or making abnormal noise. These units take more abuse than ground-level equipment because they sit in direct sun on a reflective roof surface all day. Most failures trace back to a handful of components: compressors, capacitors, contactors, and coils. We diagnose the actual cause rather than replacing parts until something works.

When to Call
When You Need Rooftop Unit Repair
- Your Tempe retail store RTU stopped cooling during a weekend and reopening is Monday

- You're hearing a grinding noise from a rooftop unit on a multi-tenant building
How It Works
Our Process for Rooftop Unit Repair
- 1
Rooftop Access and Safety Check
We confirm safe roof access and check for obvious physical damage before opening the unit cabinet.
- 2
Electrical and Mechanical Diagnosis
We test capacitors, contactors, motors, and compressor operation to isolate the fault rather than guessing at parts.
- 3
Repair
Failed components are replaced with parts matched to the unit's specifications, not generic substitutes when avoidable.
- 4
Operational Test
We run the unit through a full cooling cycle and verify supply air temperature and amperage draw are within normal range.
Tempe Context
Why this matters in Tempe
Tempe rooftops reach surface temperatures well above ambient air temperature in summer. RTU components degrade faster here than manufacturers' rated lifespans suggest, and compressor failures spike in June and July.
Straight Talk
About pricing & scope
Repair cost depends on what failed and whether the compressor is involved. A compressor repair on an older unit sometimes costs more than replacement makes sense. We tell you that up front rather than after the work is done.
