This afternoon, I visited a home in Pooler, GA to address an issue with the homeowner's Trane XR16 central heating and cooling system. After diagnosing the problem, I discovered a failed compressor contactor was preventing the air conditioner from starting properly. I carefully replaced the faulty contactor component and then tested the system to verify full cooling functionality had been restored. The homeowner now has their high-efficiency HVAC system operating reliably again.
