Coil question
 
can anyone decipher what this coil is, This is what the label states

Model: GH36S H3X42 48/H3X44 48

48,000 BTU

4/7-848

Thanks

4 ton, I believe it's an Aspen coil.

Iam thinking like you could be used in multiple cases....3ton 3/12/ or 4... but you would need to change orivice for proper size..

Thanks guys, just trying to figure out whats in this house my son bought.

The Condensor is a Bryant 563cn048D, which I know is a 4 ton.

THe coil is above.

The furnace is a York Diamond 80 P3HUA12N04801C, which I am told is a 48K BTU output heater with a 1200 CFM for ac.


Seems to me the furnace is undersized for 4 tons of ac, but based on the coil response, could be correct if the like or correct 3 ton orifice is in?

It is a 3 ton blower on a 4 ton condenser/evaporator system.

Your condenser is a 4 ton, so you would not install a 3 ton orifice in the coil. The orifice must be matched to the condenser size and type.

Your blower system is undersized in regard to the amount of a/c you have. Your system should move somewhere around 1600 cfm to accomodate a 4 ton system. Moving less air could cause freezeups, lack of proper humidity control, etc etc.

Thanks, yes I would not want to do that. The problem or question is, aside from having someone come out and take out the orifice valve, how do we know what orifice is in the coil? I tend to believe that since it specifically says 48,000 BTU's that it is a 4 ton coil.



Yes the furnace is undersized based on this, 4 ton coil and condensor, and will need to be changed out.




My thoughts are that the elderly person could not afford the changeout of the furnace when the coil and condensor were put in, or that the AC was added sometime later to the house that had heat or that the AC person misread the furnace only seeing 48000 heating BTU's.



Thanks

The only way to know which orifice is installed is to remove it and read the rating on the orifice itself. I would assume that the orifice is rated for 4 tons, since that's what's installed outside, but there's no way to be sure without seeing the stampings on the orifice.
