Dunn Electrical Service your local Authorized GE Dealer. Problems with your electrical system can be scary, stressful, expensive and even dangerous, but most electrical problems can be avoided with the right team on your side. Our technicians are required to complete many months and even years of rigorous training before they’re allowed to ‘solo’ on repair or installation work. And as a licensed electrical contractor, we insist that our technicians attend regular technical education and training programs. They are also trained in communication skills, sales, finance, management and marketing.
