Kirk ... are you sure no leaks?
Opening windows should not increase perceived cool air flow in a leak-less recirculating system unless you are feeling some other effect such as two or more open windows creating air cross-flow from outside breezes..
Nope its not perceived. When I turn on the roof vent around 20%, I can feel more are flowing from AC vents. At 100% that airflow increases a little but not significantly.
I’m thinking through this a bit so thanks for calling me out.
If there is no outside are being introduced I should hear the fan struggle while it’s trying to create a vacuum.
If i have say a leaky door I should maybe feel a cross breeze.
If my duct or ac unit has a leak I will feel that outside air being pulled through the ducts causing an increased airflow.
Am I catching on to what you are saying.
What about the theory that it’s static pressure keeping the AC from moving cold air? It does seem to blow better at night when the temps are cooler. Also what is the best way to test for a leak other than physicsl inspection?
