Unbelievable!!! A tech came out to diagnose my units not working. After arriving 2 hours late, the tech determined that one of the units had a bad capacitor and the other needed a new compressor.
He also sugessted the wiring for the breaker in my breaker box for a 9 yr. old house was "wrong" I replied that I would have my insurance company reinspect the electrical. he began to backtrack his statement regarding the bad wiring.
The tech estimated the cost would be $2200 to replace the compressor that was still under warranty in additon to recommending the entire unit be replaced at a cost of $5900.
I decided to get a second opinion from the company that originally installed the units. the overall repair cost from this company came to $900.00. i plan to follow up with the Better Business Bureau.
