My contractor says he installed a 16.5 seer system on my house but the outside unit says 13 seer. He states that with the coil in the atticit will be what he sold me, is this correct

he installed a evap. coil on a 13 seer condenser & now you have a 16.5 seer system ?

The Carrier guys have always talked about the "N" coil raising the SEER level, but I think you have been BS'ed. A larger evap coil and a TXV valve can maximize efficiency, but it is rare to see more than a single full point rise in SEER.

This is my experience, if others have info that I don't have, I would be interested too.

He said with the unit and coil combination it would be a 16 seer or 16.5 system

This is the largest increase I can find with my equipment. This is the norm. I still think you have been had.

3 Ton 13 SEER R22 AC Whirlpool W2GC336A

3.5 Ton "A" Coil WE(U,C,H,M)1P43C

To check out the validity of your contractor's claims, check your model numbers with this website. http://www.ceedirectory.org/ceedirectory/pages/cee/ceeSearchMain.aspx

Good Luck

Write down your model numbers of your outdor unit, indoor coil, or air handler.
And go the the AHRI website. And see what SEER it is rated at.

Also, your contractor should be able to show youo the tech guide SEER listing of the combination he installed.

If he doesn't have a guide, and you can't find a listing for it on AHR, then he is probably making the SEER rating up.

Agreed with all of the above: can't think of any coil match that will take you from 13 to 16.5 SEER; and check the AHRI website for you system.

Or post you system here and we can check.

Model # UANL-030JAZ made by Ruud

Evap coil : CE30D44-175L-028

This is a R-410a system

 

[dac122]

Not sure if you have the right evap coil model number but here are all possible matches for your RUUD outdoor unit. Sorry for the formatting, but bottom line the max is 14.5 SEER. If you don't have a matching coil then I doubt you are better than 13 SEER.

I think it is time you ask for documentation showing 16.5 SEER
