I have a central air and heat unit in my home. I would like to know the formula or the rules for how much air flow is needed for each room (based on square footage). Also does the size of the vent determine the max air flow? I also know there is a tool I can buy that can tell me how much air is being pushed out of the bedroom vents and can read how much air is getting sucked into the A/C. Please forgive me for not using the correct industry wording. The reason why I am asking these questions is because I dont think there is enough cool air getting to the master bedroom.
Any information will be greatly appreciated.
