This is the third time I have used Miami Electric Masters for my residence and every visit has resulted in a successful endeavor. The technician has arrived on time for the appointment and has carried out the functions required efficiently, and correctly. Alain was the technician at the most recent appointment and he diagnosed the problem accurately and was knowledgeable, neat, and very polite. He conducted himself professionally and I could not have been more pleased with the result. I would certainly recommend him and the company.
