WPM 1 - Duct Triage: Best Practices for Existing Homes (In field)

Wednesday, August 16, 2006 · 1:30 PM - 5:00 PM

Duct sealing is not the only tool in the tool box to correct problems in existing duct systems. Learn how to perform quick and inexpensive duct modifications that increase air handler flow and customer comfort. Be able to conduct simple airflow measurements and back of the envelope estimates to guide them. Find out how to lower the temperature rise on gas furnaces by "field fixes" of undersized ducts or small returns, inappropriate filters, dirty AC coils, and undersized grilles.

By attending this session, participants will

1. Learn to quickly recognize duct system flaws that decrease homeowner comfort and increase equipment performance and durability problems

2. Understand in-field methods of duct sizing

3. Use several methods to measure air handler flow and register output

KEYWORDS: airflow, comfort, diagnostics, duct design, duct repair, duct retrofit, measuring airflow in ducts, troubleshooting
