Register booster fan

Anyone have any luck with these register booster fans??

One of our bedrooms is always cold.. it is the farthest room from our furnace.

Thanks!

 

Don't waste your money! Low airflow is almost always attributed to duct design problems. Look into it first.

 

>>Low airflow is almost always attributed to duct design problems.

agreed, but I don't have thousands of dollars to tear up two levels of drywall to re-size/redistribute my ductwork...

This room stays relatively cool in the summer and warm in the winter... it is still a 2-4 degrees cooler than the rest of my house due to it's location and exposure in the winter. I'm hoping to improve the efficiency of the system in this room by stealing some air from the rest of the house... the question is does this product have enough power to steal enough air..

thanks again..

 

garbage.

as stated ..you have duct issues.

 

Sounds like a duct issue to me and FWIW i have tried these booster things. They suck and dont work.
You say the room is on the farthest run though, is the room over a garage? Do you have kneewalls in there or do the ducts run through exterior walls or thru the garage walls/ceiling? I had all these problems with a greater temp difference than you. I solved almost all of it with better insulation of that room.

 

You can add it, but if you have airflow problems, sucking air will not increase airflow. Now, if you can add an inline blower to your trunk that feeds that part of the house in question, you'll be able to increase the static in that trunk and get more flow ONLY if your sure your duct hasn't come apart and you have no restrictions such as closed dampers or crushed duct work. One way to check to see if your duct is restricted or is a bad design is to tape cardboard over all the registers in the house but the one in question and turn your fan on ONLY. Do not turn on heat or cooling. Check your airflow before doing it and check it after you seal everything. If your airflow did not increase at all or very little, you have other issues. If it had a noticable increase, you were able to build up enough static pressure to force the air out of the vent in question.

The only reason I am asking is because I went to troubleshoot a house a few years ago for a friend who said he had no airflow at the end of his house. He did what I said and he called me and said air is blasting out of his room in question. What the HVAC contractor did who built his house was to run 18" duct down the center of his house. He added an 18"x18"x8" tee-wye at each branch. He never reduced the duct work. It was 18" the whole length of his house. By the time the air moved through half of his duct work, he had no static left to make the air move.

 

Forget the fan in the duct they just dont work at all. Have you tried to close down all the other registers in the home just a little. Then see if that helps???????

 

thanks for the note.. yes.. i've closed some of the registers a bit but will make a few adjustments...
