Case Study: Redmond RTU Replacement
Overview
This case study highlights how our commercial HVAC team completed a full RTU replacement project in Redmond after an unexpected rooftop unit failure. The business experienced a sudden HVAC shutdown that threatened operations, tenant comfort, and revenue. Our technicians responded the same day, performed a full RTU diagnostic, and delivered a complete replacement solution that restored the building’s HVAC performance with zero downtime.
The Challenge
A business in Redmond contacted us with an emergency: one of their rooftop units failed without warning, and the second RTU showed clear signs of end‑of‑life. The building relied heavily on these units for ventilation and climate control, making the failure a serious operational risk.
Key issues identified:
- Sudden RTU failure
- Second unit operating at end‑of‑life
- Risk of downtime and tenant complaints
- Potential safety and code compliance concerns
- Need for fast, reliable commercial HVAC service
Our Solution
We deployed a commercial HVAC team the same day to perform a full rooftop inspection and system diagnostic. After confirming the failure and assessing the second unit’s condition, we recommended replacing both RTUs to prevent future breakdowns and reduce long‑term operating costs.
Work Performed
- Same‑day RTU diagnostics and system evaluation
- Replacement of both aging rooftop units with new Trane systems
- Coordination of crane lift and all rooftop logistics
- Securing permits and passing the final inspection
- Repairing damaged ductwork and correcting the gas line
- Installing service outlets for safe future maintenance
Results
The Redmond business avoided costly downtime and restored full HVAC functionality within a short timeframe. The new RTUs improved energy efficiency, airflow, and reliability, while the updated gas line and ductwork ensured long‑term safety and performance.
Project Outcomes
- Zero operational downtime
- Improved HVAC efficiency and reliability
- Fully compliant installation with passed inspection
- Reduced risk of future failures
- Enhanced comfort for tenants and staff
When Is It Time to Replace Your RTU?
A rooftop unit doesn’t fail overnight — it gives warning signs long before a full shutdown. For business owners and property managers, recognizing these signs early can prevent costly downtime, emergency repairs, and tenant complaints. Here are the key indicators that it’s time to replace your RTU instead of continuing to repair it.
The Unit Is 15–20+ Years Old
Rising Energy Bills
Frequent Breakdowns and Rising Repair Costs
Loud Noises, Vibrations, Unusual Smells, Inconsistent Temperatures or Poor Airflow
