A coil matchin on Goodman

[hageman6]

This is an after the fact question because this unit was installed last year. I had a CLQ -36-1 14 seer ac unit installed with a GMNT080-4 80BTU Goodman furnace with a U59 coil with an XV24-60 TXV valve.

I am no pro so bear with me, it looks like maybe the A coil is really too big and I am wondering if this will make this unit less efficient than the propsed 14 seer. In running it last year it sure seemed to do a nice job in keeping the place cool and dehumidified and my bills did go down even thought I kept the house about 3-4 degrees cooler, but what I have seen on this is that 1/2 to 1 ton oversize A coil would probably be the limit. (Maybe I am concerned over nothing)

The installer believed he could get even a little more efficiency with this A coil. The installer did a very nice job and has very good references and the price was very fair, so I have no reason to think he is mis leading me. But that does not mean he may be wrong in this instance.

By the way I live in Kansas humidity is a little bit of an issue but the unit seems to do fine in getting rid of humidity.

Thanks for educating me.

sounds like its right, 14 seer needs a big coil you need surface area to make it work. find something new to worry about

I just checked the ARI website and the U59 is not listed as a matching indoor coil for the CLQ36, here is a list of matching coils and their respective ratings, the U59 and U60 are similar so you are probably close to 13.5 SEER with that combination

CLQ36-1* 503717 U60/UC60+EEP 13.50
CLQ36-1* 503721 U62/UC62+EEP 14.00
CLQ36-1* 503715 HT61+EEP 14.00
CLQ36-1* 503713 HT4860+EEP 13.50
CLQ36-1* 503719 U61/UC61+EEP 14.00
CLQ36-1* 503697 CA*X061*2*+EEP 14.00
CLQ36-1* 503705 CHPX048D2*+EEP 13.50
CLQ36-1* 503695 CA*X060*2*+EEP 13.50
CLQ36-1* 503707 CHPX060D2*+EEP 14.00

Goodman coil usally works well with bigger surface area.
