Hello All. My family room which is at the back of the house and furthest room away from the HVAC unit always stays a little too warm (summer) and too cold (winter) compared to the rest of the house. Although it might be possible (but difficult) I could possibly put a bigger duct in where it chokes down to make it's final run to the register, I was thinking instead to try one of those inline duct blower fans. Does anyone have experience with these ? Will it make the cool air warmer and hot air cooler ? Will it increase the pressure ?

Next question is wiring it up. you can get some sort of thermostat and plug the fan into that or wire it directly to the fan blower I think. I would rather have it wired up directly to the HVAC units so that it only comes on when they kick on. Is this difficult/possible ?

Thank you for any help you can provide.
