I bought this to blow out the A-coils in my HVAC air handler. It worked perfectly, and blew out a ton of debris that was blocking the airflow in my HVAC system. After using this, the airflow at my registers in each room went from detectable at 1234; to detectable at well over 7' away! My entire HVAC system usage also dropped about 20. Totally great tool.
