Jarvis Press Case Study – Commercial HVAC, Rooftop Units, CRAC Units & Split Systems
Commercial HVAC Case Study – Jarvis Press
When B.I.M.S. first arrived at Jarvis Press, the facility was experiencing multiple issues across its commercial air conditioning systems, including rooftop units (RTUs), computer room air conditioning (CRAC units), and split systems.
These HVAC problems were directly affecting comfort conditions throughout the building and were beginning to impact production quality—especially environmental conditions that can cause paper to stick or become unstable due to heat and humidity fluctuations.
Initial System Problems
At the start of service, Jarvis Press was dealing with:
- Multiple failing commercial rooftop units (RTUs)
- CRAC unit failures affecting critical control and equipment areas
- Split system malfunctions across offices and production spaces
- Inconsistent cooling and temperature swings throughout the building
- Lack of structured preventive maintenance
- Equipment operating in a reactive “repair-only” condition
- Reduced overall HVAC reliability and comfort control
Step-by-Step System Restoration
Instead of attempting to fix everything at once, B.I.M.S. implemented a systematic, priority-based approach.
1. Targeted Repairs (One System at a Time)
We focused on restoring each system individually:
- Diagnosed and repaired rooftop unit failures
- Restored CRAC unit operation in critical areas
- Repaired split systems affecting occupied and production zones
- Corrected airflow and control issues impacting performance
- Brought all systems back online in a controlled sequence
This approach allowed the facility to regain cooling capacity quickly while avoiding additional system stress.
2. System Stabilization
Once equipment was operational, we focused on stabilizing performance:
- Balanced airflow throughout the building
- Corrected temperature inconsistencies between zones
- Reduced short cycling and unstable operation
- Improved overall system runtime reliability
- Restored consistent cooling across the facility
Preventive Maintenance Program Implementation
After full system restoration, B.I.M.S. transitioned Jarvis Press into a structured preventive maintenance program designed for commercial HVAC reliability.
This included:
- Scheduled quarterly maintenance visits
- Rooftop unit inspection, cleaning, and performance tuning
- CRAC unit servicing for critical temperature zones
- Split system coil cleaning and operational checks
- Refrigerant level and system pressure verification
- Electrical inspections (contactors, capacitors, wiring)
- Belt, motor, and bearing inspections
- Drain line cleaning and condensate management
- Airflow verification and system optimization
Results
After system restoration and ongoing maintenance implementation, Jarvis Press experienced:
- Improved commercial HVAC system reliability
- Stable building temperatures throughout all areas
- Reduced humidity-related production issues (paper sticking prevention)
- Fewer unexpected breakdowns and service interruptions
- Better performance from rooftop units, CRAC units, and split systems
- Increased overall comfort and environmental stability
Long-Term Value
With a structured preventive maintenance program in place, Jarvis Press now benefits from:
- Predictable HVAC system performance
- Reduced emergency repair costs
- Extended equipment lifespan
- Improved energy efficiency through properly maintained systems
- Stable environmental conditions supporting production quality
- Lower total cost of ownership for commercial HVAC equipment
