 Trustindex verifies that the original source of the review is Google. The team at Thermoelectrics were fantastic! My Company used them for electrical work and COC. The communication, co-ordination and efficiency from Nikita was superb. The onsite team of P, Emile and Warwick were diligent and professional. They were in good spirits despite going the extra mile to get the job done. Highly recommend Thermo for your needs.

 Trustindex verifies that the original source of the review is Google. My go to team from now on. My municipalty main supply in my dB desided to short to neutral and burn 22:00 on a Saturday evening, and the municipality breaker did not trip. It was fireworks inside my house, not a good sight or feeling. After phoning 10 different electrical companies stateing 24/7 on call, some even answering and saying they will only come the next day as it is late, Warwick had no hesitation to come through and assist. The house would have burned down if it was not for Warwick. He stayed the entire time to ensure the municipality shuts off the power to my house, worked on my dB till 03:00 in the morning to ensure we can power up safely again and wanted to still clean where he worked. Great service, great work ethics, great quality standards. Thanks again.
