New Customer Report of Excellent Service

Jonah's service call was an impressive first experience for us as a new customer with TE Certified. His thorough diagnostic process including contacting the unit's manufacturer customer support is an example of standard of excellence more contractors in Gwinnett County should learn from.

Breaker panel replacement & whole home new switch and outlet installation

The service technician was highly skilled and knowledgeable about the work performed. He was efficient in the performance of the work and kept us informed as the work progressed. If complications were experienced, he was quick to explain the issue, the resolution and if any additional charges were to be incurred. If future work is required, we prefer Hubert Klejzerowicz assigned to our work order.

Unit does not have e standard flood protection. Due to cost of repairs and age of unit recommend replacement.

When we arrived the homeowner had turned the main breaker off and had the panel cover off already. During our troubleshoot we had discovered multiple breakers in the challenger panel had burnt up. We replaced the panel, added smoke detectors throughout the home, installed surge protection. Installed two dedicated outlets to the right of the panel in a two gang box. Old dryer circuit and sauna circuit are capped off and not install in breakers as per homeowners request. Bedroom 4 replaced backstabbed switch and outlet below smoke detector. Bedroom 3 replaced backstabbed outlet below smoke detector. In the office replaced backstabbed outlet below smoke detector. In the upper hallway replaced two 3way switches below smoke detector on master bedroom side of the hall. Bedroom 2 replaced backstabbed outlet below the smoke detector. Everything tested and working properly.
