Trane XL19i one compressor failure. What to do?
I have a Trane XL19i 4 ton unit which is 9 1/2 years old. The 1st stage compressor has been diagnosed as bad. The 2nd stage appears to be ok. I only have the standard 10 year parts only warranty. My service provider has recommended replacing both compressors (the parts are covered by the warranty). The cost to do the repair is a little over a $. The system is working now using the second stage compressor only. It appears I have 3 options:
1. Do repair. Parts warranty will run out in 6 months.
2. Purchase new 4 ton unit (entire system).
3. Do nothing now and hope that the unit will continue to work for a few more years before I have to replace the whole system.
I would appreciate any advice on what would be the best course of action. Thanks.
