Should I add an additional intake for my HVAC system?

Filed Under HVAC 

rreym asked:


I want to add an additional intake alongside the existing one for my HVAC. Does this help to get better air flow throughout the house?
I ask this b/c i think my existing return is too small. the return is 12 x 24 and it’s cooling a 1200sq ft home. Does this sound about right?

      Rule of thumb is that the return is approxiamaty 3xs the supply.

      Not necessarily. Proper duct sizing, material, and location of supply and return optimizes air flow.
