Jeff was very professional, knowlegable and is a highly compentent technician. He did a thorough analysis and diagnosed our heating and cooling system, in a short time, explaining our options and price before each step. In addition to needed maintenance, he suggested follow up maintenance for continued peak performance. He explained our needs in understanable terms. He is very customer oriented and provided good service for the price. I high recommend Advantage Heating and Cooling as a service provider.
