No heat from vents : Duct work problems ?
 

Hello,
I noticed that, when the central heat is on in our house, two vents
(in two bedrooms) don't seem to have any air flow out of them (they
are the only vents in the room, so I don't think they are intake
vents) . So these rooms feel cold. Other vents in the house seem to
work and hot air comes out from them. But nothing from these two
vents...

I would appreciate any assistance to help me understand what I have at
my hands -

1) If this seems like a duct work problem, how are such issues
fixed ? Is it very expensive ?
2) Can duct work get dis-connected within the walls ? If so, does
someone have to tear open the walls to fix it ?

Thanks much.

I had one going to a kids bedroom that stopped working. The kid was
dropping things like playing cards through the grate. *I had to snip it
open and clean it out.- Hide quoted text -

Thanks. Sorry for my ignorance here...I have no idea about how ducts
are constructed . But how do I find if it is obstructed or broken ? It
could be somewhere deep in the duct work. I tried peeping in and
couldn't see anything.

You could have dampers near the furnace, I had the imstalled to
balance my system or close off a room not used

Ducts are pretty simple and generally not much goes wrong with them.
The first thing to check is whether the vent itself is turned off
(closed). Sometimes they have a lever or something that lets you open
and close it. If you can see through the vent grate into the 'dark
beyond' then it's open. You can also compare its appearance to other
vents that work. If the vents are open, there may be a baffle in the
ductwork that is closed. This would probably be located someplace
where the ductwork is exposed, like the basement. The main strategy
there is first try to figure out which duct(s) leads to the rooms in
question. By the way, are the two non-working vents on opposite sides
of the same wall? In that case it may be one duct that serves both
vents. Anyway if you can find the right duct(s) in the basement, look
for levers or handle-like things sticking out from the ductwork. If
you find one then try switching the position and see what happens. If
that doesn't pan out, maybe it's time to call the heating and cooling
company. Very unlikely that it would involve tearing up walls. -- H

Go down in the basement and look for damper handles on the ductwork.
You should have dampers in each duct so you can control the amount of
air to each vent. Perhaps you have one or two dampers that are closed.
The handles should have some resistance to them as you feel the damper
turning inside the duct.

A while back I spent an afternoon mapping the ductwork in my house. I
simply turned the blower on high, closed all the dampers in the
basement and then opened them one at a time, walking through the
house, feeling the air at each vent. I then went back to the basement
and used a Sharpie to mark the room location on the ductwork next to
each damper handle. I found that in some cases, one damper closed off
more then one vent.

It really helped me balance the output better by closing off rooms
where I wanted it warmer/cooler and half-closing dampers for areas the
didn't need as much heat/cool.

Remember that hot air rises and cool air falls, so the vents should be
re-balanced when you switch from heat to AC.

Thanks Everyone for your suggestions. Much appreciated. I will try
looking for the dampers in the basement and hopefully I find the right
one.

they may have dampers in those runs and they may be shut.
