TROUBLESHOOTING | ROOT CAUSE ANALYSIS
Finding the Cause.
Not Just the Symptom.
FUNCTION provides independent technical investigation and troubleshooting for complex mechanical systems, building automation, and operational performance issues.
Our approach combines engineering analysis, field experience, controls knowledge, and system performance data to identify why systems aren't operating as intended.
Rather than treating individual symptoms in isolation, we evaluate how equipment, controls, installation, and operating conditions interact to determine the underlying cause.
WHAT WE INVESTIGATE
Complex Systems. Practical Answers.
Technical investigations focused on identifying performance deficiencies, understanding system interactions, and developing practical corrective actions.
Mechanical System Performance
Investigate HVAC and hydronic system deficiencies, including flow problems, temperature instability, equipment capacity, and operating conditions.
Evaluate sequences of operation, control logic, sensor data, and equipment responses to identify problems with system operation and integration.
Building Automation & Controls
System Integration & Interactions
Identify conflicts between equipment, controls, and supporting infrastructure that can cause unexpected behavior during normal or transitional operation.
Trace recurring deficiencies to their underlying causes and develop practical recommendations that address the problem rather than its symptoms.
Root Cause & Corrective Action
OUR APPROACH
Follow the Evidence.
FUNCTION reviews design documents, sequences of operation, construction records, equipment information, and operating trends to develop and test potential explanations. Field observations and targeted testing help distinguish symptoms from underlying causes.
A successful investigation starts with understanding how a system was intended to operate, how it was actually constructed, and what the available evidence reveals.
The result is a technically grounded assessment of the problem and practical recommendations for resolving it.
