RECENT WORK

Dispatched to commercial site in Allen, TX to address HVAC performance issues on a Carrier rooftop unit. Upon inspection, found the dual run capacitor (serving both compressor and fan motor) was weak and out of manufacturer’s spec, causing intermittent operation and reduced cooling performance. Replaced faulty dual capacitor with OEM-rated component. Verified proper microfarad rating and secure electrical connections. Tested unit operation after replacement—compressor and condenser fan motor both started and ran correctly. System pressures and amp draws returned to normal range. Rooftop unit is now operating as designed.
