return grille positioning..

[rkgtech]

Hi all

Since you guys are the gurus of HVACs - here's a quick question if you can help.

My furnace (split system) is on the mezzanine above the kitchen (in a HVAC room along with the water heater). The return grille faces the mezz area (don't even start talking about the noise !!). The air on the mezzanine is ALWAYS warm (of course). Is it acceptable for the furnace to keep reheating warm air? What are the repercussions of this?

Thanks!

PS - if you have a solution to the huge noise problem, that would be great too or better yet a SUPERB HVAC specialist in brooklyn, ny

Thanks much all !

A pic would help.

A pic would help.

I was going to say the same. Need pics to give an informed reply.

sure.. thanks much.. adding 3 pics here.

I took one pic from inside the HVAC room (the room is also used as a plenum) - you can see the filter from inside and to the right is the water heater.

Outside the grille, since everything was a hard surface, I added 2 soft curtains to absorb the sound - so, the return grille has blinders :-)

The mezzanine is about 8 ft above the main floor and looks down onto the living room - the grille is on the same level as the mezzanine.

the ceilings are about 14 ft high and it is a 930 sq ft apt. I have a GY9S120D20DH11J YORK furnace.. wonder if it is too much for the size of my apt.. maybe that's why the noise..

Does this help? Thanks much!

Can't see the pics. As far as the furnace size, it appears to be over sized for the area but without all of the specifics, it's impossible to give an accurate assessment. That is a 120,000 btu unit with a 2000cfm blower (max rating). Using a single return grill certainly could result in a fair amount of air noise.

thanks for the response.
weird.. i can view them when i click on them.. are they not showing up when you click on the img links?

i was thinking a 3.5 ton unit would be enough but i am not an expert... hence i do need an expert to come in.. the ceilings are high and the apt has exposure on all sides but 2.. so there are a lot of factors to consider :-(

Same here, no pics. I think the site has a few bugs.

The box for image attachments is there but no links in the box

Don't guess at it. At the top of one of these pages is a link to do your own load calulation. Try it.

The link works but, I still don't get it. I guess I need a more over all pic, a wider angle, I'd have to say.

do u mean, looking from the mezzanine onto the HVAC room itself showing the grille position (or rather the blinders position)?
