Seminar 37 -- HVAC Maintenance: Using Field Test Data to Benchmark and Improve System Performance

This product contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

The typical HVAC system operates 40% below specified capacity and efficiency once it is installed in a building. During routine maintenance visits, changes in the performance of an HVAC system can be diagnosed in less than seven minutes by recording and comparing seven simple airside field measurements. This test method compares benchmarked data to pinpoint the causes of deterioration in system airflow, economizer performance and duct system functionality and enables detection and surgical correction of the uncovered and often invisible system defects.
