“As always, superb knowledgeable service from Tassio! This morning Jennie helped us. The office staff are always friendly, courteous, and responsive. The technicians, like Thomas today, are well trained to be able to explain the problem simply, propose a solution or solutions, and secure an estimate for our approval on the spot. They all carry electronic devices for rapid communication with their office and can generate an official estimate or invoice immediately. Their work is efficient, expert, and clean. A few years ago we became dissatisfied with our previous long term provider of HVAC services. We had seen the very distinctive Tassio trucks in our neighborhood and decided to give them a try. We wish we had made the switch sooner!”
