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.
