A/C Vent Booster Fan
Intro: A/C Vent Booster Fan
We have some rooms in our house that never seem to cool down because the A/C doesn't seem to move enough air. I've been told to make sure the filter is clean and NOT one of those pleated hypoallergenic ones, (cheap free-flowing is better for a/c), open all the vents and leave the thermostat fan switch in the ON position; not AUTO. Some rooms just need a little boost though, so we found this little fan that fits over the vent. It works great but cost $35.
I started withe a 4" fan and a plastic tub that fit over the register.
Find a fan that you can take apart or it'll be more work if you have to drill and pop-rivit it back together.
I had to drill rivitsĀ and remove the stand (watch your fingers...)
I attached the cover to the inside of the tub and carefully cut out the inside, leaving a little extra around the screw holes.
After re-assembling the fan, I drilled a hole for the cord.
The finished product with cool feet.

post addition. For those who would like a visual of what a butterfly valve is, when referring to my earlier post.

Mechanical Engineer here, ... essentially the same problem in my two story home. Typical complaint, hot upstairs during summer a/c use. .. overly hot downstairs during winter furnace use. Inefficient ducting is the cause in almost every case. Problem with my home is energy cost in both seasons, even with solar it has been $600 month during peak of both seasons.
HVAC wanted $2500 to redo ducting, install baffles .. ect. Instead I purchased cheap 12v solenoids (2) , roll of HD doorbell wire, 2 position switch, 12v transformer and made "butterfly" valves. I installed them inline on the main ducting for upstairs, downstairs. Total project took 2 hours.
Now, a simple throw of the switch ( mounted to thermostat ) either increases overall a/c output upstairs for summer, or switch lower position increases furnace output downstairs. Huge difference, monthly bills now sub $200 ( with solar ).
Total project cost ... $85.00
This ducting control is much more effective than trying to push or suck air out of vents with a fan. It's also more cost effective in the long run with comparable project costs. I'm actually surprised that you don't find these kits ready made at the big brick and mortar stores
