boster fn in Return duct?

[bam]

Does it ever help to put a booster fan in a return duct as opposed to the supply ducts? Might it help to install a fan in the Return in addition to the supply ducts? I have a room where the ducts are very hard to reach and I have to increase the flow one way or another.

No. That is my opinion. It will not help.

Predicting air movement is admittedly very difficult.

Have an HVAC company take a look at the duct.

No it will not help.

Sure it will, put in about a fifty horse airfoil, that ought to give you plenty of boost

If it doesn't work why is it used in commerical applications all the time?

The OP gave no actual details of any actual situation. I have since thought about it, and suppose there could be a 'situation'.

I once heard of a guy who had to heat/cool a tree-house with home A/C to get around some stupid home-owners' association rule, for example.

Now , I know you have a limit with supplying air, in effect,.. room pressurizes and then the air-flow stops.

I suppose, in some bizzare 'circumstance' it is possible you could not put in an adequately sized return or found it undsireable to do so for some reason. That could overcome the 'pressurization' problem. To be fair, could be a good idea in some strange case. I have never seen it done nor consider it practical in any normal case, just imagining a situation where it could be contemplated as a rational solution...
