HVAC and remodeling kitchen

 

I am going to remodel my kitchen. Currently there is only one forced air A/C
duct in the kitchen in the wall near the floor. This wall will be covered by
cabinets as well as all other available kitchen walls. Where is the best
place to relocate the only existing duct I have? I see the only place for it
is to move it higher above top cabinets. I also plan to add a couple of more
ducts and probably one return duct. Again the only place I see for those
additional ducts is in the walls above top cabinets. I cannot put them into
ceiling because of ceiling joists. Any advise would be appreciated.

Don't go adding ducts without understanding the impaceon the rest of
your system.  A return duct in the kitchen sounds like a great way to
get kitchen odors spread throughout the house.  In some jurisdictions it
is against the building code.

 


In the toe kick space, like most installs.



Which would violate code for return air!



Call a professional and get it done correctly.

Putting toe space grills in houses with A/C and a basement or
crawlspace can be a mistake.  Normally, the duct is attached to the
floor under the cabinet under the cabinet.  This pressurizes the space
under the cabinet with cold air.  The subfloor under the cabinet
assumes supply air temperature.  If there is any humidity in the
crawlspace or basement, moisture will condense on the underside of the
subfloor.  Conditions are then ripe for mold growth or wood rot.  Even
if you duct the air all the way to the grille, there can still be
problems.  The floor in front of the grille will also approach the
supply air temperatures.  About 10 percent of my business involves
fixing problems with damp crawlspaces.  The biggest problems are with
houses with toespace grilles  Avoid toe space grilles unless you are in
a very dry climate.

First, if I do it, it's ducted all the way to the grill.

Second, I live in an area where humidity isn't an issue.

Your thinking, and sharing your knowledge, that's good.
That's the nice thing about the NG, it's made up of people from all
different areas of knowledge.
