Vertical VS Horizontal Furnace and Evaporator
Terry Elam
Considering that space is not a problem and our summers are longer
than our winters here in South Texas I am wondering if there is a
performance advantage in one or the other. The contractor is pushing
me toward a vertical unit but it seems I read in one of the posting a
few months ago that horizontal may be the way to go.
Also any wisdom on Trane vs Lennox vs Carrier
Thanks for any help

Keeping the duct work in the crawl space will mean less temp. difference & that spells
$$ savings and slightly cooler grille temps. Not a big deal, though. Also, a horizontal
furnace/air handler will usually have a much quieter return air noise level as well.
Assuming the upflow unit will have the return air directly below it.
Trane vs Carrier?
Pay more attention to your dealer than the brand. Those are both top systems but its
always the installer & service you get that makes a system great and the owner happy.
Good luck

homes have supply ducts in the slab or crawl with returns either attic
or floor. I hate seeing anything in the attic personally. It gets
extremely hot up there and even with insulated ducts, heat penetrates it
and part of the work the A/C does is getting attic heat out of the
ducts. I especially hate to see the blower in the attic. MURDER to work
on in the summer. Use a closet somewhere with a vertical unit.
I personally think Trane is about as good as you can get. Lennox has 2
lines, their Elite line is good, the Value line rather cheap. Carrier
has 3 lines. Their Tech 2000 is fine, the cheaper models are rather
generic and cheap. Don't oversize!!! As another post said, quality of
installation is very important!

Hi! I`d throw in a couple of more comments. Use ductboard supply and return
plenums to really cut down noise on a horizontal unit. Don`t overlook the fact
that flex duct insulation is on a mere 3/4" which isn`t too good for Houston
Summer heat. Want better?? Wrap the flex with 1" vinyl.

what about the R-8 and R-11 varieties of flex duct?????
stick with sound lined sheetmetal fittings,,,, much more durable
