Sarah Mines may be new to the company, but comes with a wealth of information to help the customer understand the technical aspects of the product, healthy patience, and is definitely customer-service oriented. She was on site most of the day the air-conditioner/furnace were installed. The five techs worked incessantly, and skillfully maneuvered all equipment and materials through my house with ease and care. They insisted on vacuuming and cleaning up after completion of the installation. They also made sure I was comfortable with operating the new system. Unfortunately, due to the uncooperative weather conditions, they were not able to complete their testing of the units. However, they came back to complete their tests and passed the city inspection with flying colors. I highly recommend this Advent team to anyone who expects nothing less than great customer service and quality HVAC products!
