You are the original owner?

What was warranty when purchased?

You might consider a second opinion.

Since you are nearing end of cooling season and weather is moderating, you could wait till the Spring to make a decision.

IMO

jrkjrk,

What you have is a somewhat common failure in rheem/Ruud gas packs.

Coil is very expensive when out of warranty as yours is. But it shouldn't be as much as a new one, but including labor to install probably nearing 1/3 of a new one depending on your area.

8 years old in not that old but you should ask them if you have the stainless steel heat exchangers. If you do not then you will most likely have a hole in them or are about to. Whereas the heat exchanger is under warranty, labor is not, and labor is also high to replace them.

There are a lot of things to consider when you have a failure such as yours. Your company should have went over it more with you.
