Repair to an old system

I've recently purchased an older house with a well maintained (documented) AC, and the compressor broke...
Capacitor is fine, board is fine...

The unit is a 4 Ton Goodman CK49-1 with a bristol compressor rated at 10 SEER and uses R22.
Google tells me that the original part, B9266672 was replaced with ZR42K5EPFV800 and that second one has been discontinued.
I believe in Alabama the current minimum is 14 SEER, is a replacement compressor even possible for this unit?
I have a home warranty which should cover the repair, I'd like to have all the info in case they try to deny the claim.

Thanks

Welcome to the forums.


Yes.... a replacement compressor is available. Unfortunately you have no say what they do. More then likely they will just replace the compressor. Otherwise they'd need to change the condenser and the coil in the air handler.

That's the goal.
What I'm trying to figure out is whether they could legally replace the part, if such a part exists, being below 14 SEER
And what's my potential upside may be; a higher SEER 410A unit and all the related upgrades...

...And what gimmicks they may try to deny the claim.
I have no idea if this company is reputable.

Thanks Pete,

I'd be fine if they replace the compressor, the unit did a great job of cooling off the house so far this summer.

They can legally replace the compressor. A limited amount of R-22 is still available at an insane price. They should recycle what is in your system. You have a service contract with them ? They cannot deny a claim. They will choose the least expensive repair route.

I have a home warranty which covers AC.
I can't seem to find what the SEER rating is for the ZR42K5EPFV800 compressor, which seems to be discontinued but still available as a replacement compressor for my unit.
If that unit is below SEER 14 then I don't believe it can be installed in Alabama.

The oil should be tested for acid if it was a burn.

The SEER of a system is determined by all of it's components.... not just the compressor.

Thanks, that's good to know.
The air handler had been replaced a few years ago with a Trane XL80, everything else is original to the goodman system
