Fresh air intakes


Any and all info appreciated!Is there any kind of kit I can buy to install on my units to introduce outside air to my system?I assume it will involve some kind of motorized damper actuator?Thanks a lot for any input.

The best way to go for that install would be a couple ERV's/ HRV's. Check out the Honeywell or Carrier websites, both make great products.

No, the more returns the better. Ideally, twice the amount of return as supply will have half the velocity (desirable) and no air noise.
