HVAC Return Air Ducting is Important - Lots is Better
HVAC return air is important. This will allow you to choke down rooms possibly on the first floor that are drawing too much air. This, in turn, creates a greater suction in the rooms that really need cool air. The main floor has 3 supply and 3 return registers
Supply Vents vs Return Vents | How to Identify HVAC Vents
There are two types: supply vents and return vents. If your indoor air handler is the heart of the system, the supply ducts are the arteries and the return ducts are the veins.

Return and supply temperature difference
I recently purchased a condominum unit with a very old air conditioning system (1980's). A home inspection revealed a return/supply difference of only 13 degrees.
