Diagnostic-First Furnace Repairs—Not Parts-Swapping Guesswork
Most furnace service calls end with replaced parts but no performance testing. We use calibrated instruments to measure combustion efficiency, gas pressure, temperature rise, airflow, and system performance before and after repairs. This diagnostic-first approach identifies root causes—not just symptoms—and ensures your furnace runs safely and efficiently after we leave.
Every system is designed using:
- • Combustion analysis using digital analyzers to verify safe, efficient operation
- • Gas pressure testing to ensure proper burner performance
- • Temperature rise measurement to verify proper heat output
- • Airflow testing using static pressure mapping and velocity measurements
- • Electrical component testing on igniters, flame sensors, and control boards
- • Post-repair performance testing to verify proper operation and efficiency
This is why we diagnose first—not just swap parts and hope it fixes the problem.
