I recently hired Powertech and I am happy with their install. Scheduling was easy, and the electrician arrived on time. Jake was professional, knowledgeable, and explained everything clearly. He also found a minor issue with the fan and advised how it could be fixed, he gave valuable advice. The pricing was fair and transparent. Quoted and invoicing all straight forward too which helps!
