Confirming Condenser/Coil Match
I am about to pull the trigger on a new Condenser and Coil combo installation and wanted to confirm with this board that the following is a correctly matched system. I am comfortable with the contractor, just wanted to double check the model #'s. Furnace is still in good shape.
In Houston, 1800 sqft home. Built in 1994.
American Standard Allegiance 14 - 410A 3 1/2 ton
American Standard Horizontal Coil 3 1/2 Ton (with TXV installed)
Replacing due to bad leak in the current evaporator coil (Carrier builder install).
Thanks for any input.
I'm NOT a HVAC tech but tonnage seems high for SF. Was a heat calc done?
ARI Ref #: 672834
AMERICAN STANDARD, INC. Allegiance
1RCU-A-C: ARI Type
$274: Cooling Cost

Well, how about that!
Thanks for the info.
Not too sound rude, but if you are not a tech or in the field you really shouldn't comment.Your question is right on about the calc, but how do you know what sounds too big?

No offense taken.
I live in Atlanta in 1700SF house with 3 ton unit and I'm battling an oversize issue. Just trying to help someone else living in similar size house in similar geography not make the same mistake i did; i.e take the word of contractor saying I need to upsize to 3 ton WITHOUT heat load calc.
This board's help me in the few days I've viewed. Just trying to give back what little I can.
See my thread on heat load calc.
