Unlike many other HVAC companies, Advanced Control Corporation is genuinely interested in engaging their customers. From my standpoint, Sean has defined his company by clear and consistent communication. There is no call center to dispatch a tech or a need to retrain a tech every time they come to provide service. You get a call back from Sean either way. He even informs us when he is on vacation and provides us with useful and dependable backup contacts from Advanced Controls Corp. When you place a call for service, you can trust that a return call or arrival for help is not far off. We are very demanding, and Advanced Control Systems always delivers the goods.
