Our MB is on the South side of our house in AZ. It stays warmer than the rest of the house. I am considering installing and 8" in-line booster fan at the 'T' where the supply duct (flexible) where it branches off to the 2 supply registers.
Two questions:
-
Would this be the proper alternative?
-
Can I tap off of the 110 VAC to the blower motor so that the booster fan would only run when the blower runs?
So, I guess there is really a third question: Will it matter if the booster fan runs when the supply fan is off?
Please let me know your thoughts. Thank you.

The 1 time I used an in-line fan as you are suggesting it made more noise than it was worth. It produced very little increase in air flow.
I would have an HVAC company look at your problem to see if there was a simple fix or as the others have said plant trees, and some type of shading or add a separate cooling device. Since you are in Arizona, could you add a "swamp cooler" just for that room?
