Trust me, they're easy to miss. I lived in my place for 15 yrs before seeing one on mine and realizing it actually moved. I just found another one elsewhere just last year.
They are very discreet/low profile.
I'm no HVAC person but I think their purpose is to balance airflow and prevent exactly what's happening in your place. Super hot near furnace, cool farther down the line. I think a good way to test is to compare airflow out of the vents in the hot parts of your home vs the cooler areas. If it's blasting out of the hot areas and much slower in the cool parts, that's your answer.
