I diagnosed and repaired a noise issue on an American Standard HVAC system in Denton County. Investigation revealed a loose blower wheel causing vibration against the housing and worn belt creating a squealing sound. Performed complete blower assembly inspection, tightened mounting bolts to factory specs, and replaced worn drive belts. Also lubricated all bearings and checked motor mounts. The system is now running whisper-quiet. Available for diagnostic services across Denton County. Licensed and insured!
