If all your diffusers have very low airflow (down below a hundred cfm), you might need to check both the lover motor from the HVAC unit or the inside on the duct. Too much dust gathered inside the duct will reduce the airflow.
It’s essential the duct collar on the plenum box of linear slot diffusers is place within the facet of your plenum box instead of on the top. I’ve coated The explanation in my click here post with regard to the 4 sorts of HVAC plenum bins.
