"Update: I had been given estimate by another HVAC company of $1800 to replace a part on the unit to stop freon leakage...James from GSM gave me alternative to seal the leaks with sealant at a cost of $567. He explained the process in detail and said it did carry a limited warranty. I decided on this option."
