Airflow is the life blood of an HVAC system. Most technicians fail in their diagnostics every day because they don’t understand that refrigerant, combustion and temperature diagnostics are usually incorrect when system airflow is assumed. It’s estimated that up to 50% of repairs are ineffective based on this missing link in HVAC diagnostics.

Learn how to use the four steps to plot fan airflow so you can do it in less than a minute – once operating static pressure and fan speed have been determined. The downloads available with this webinar include a test procedure and practice exercises.

Learn how to plug fan airflow into your HVAC diagnostics to quickly and effectively troubleshoot the systems you install, service and sell. This will increase your professionalism, reduce callbacks, and improve your ability to help your customers understand the value you add to their comfort, efficiency and safety.
