Failed refrigerator unit

[JohnnyFry]

I woke up to the odor of ammonia this morning...failed fridge cooler. I am in central Texas at a relatives house and will be ordering a replacement cooling unit tomorrow and we will install it when it arrives.

Does anyone have strong ideas of what supplier to deal with? There are several, offering 3 yr, 5 yr and lifetime warranty, rebuilt or new?

Thoughts would be appreciated.

Thanks,
John
