Jonathan came by for our winter check up of our heat/air unit. He was on time and introduced himself when I opened the door. Showed him where the unit and thermostat were and he went to work. On occasions he would stop and point out things, explain the need for continued maintenance over time and at the end pointed out their upgrade service plan with all of the benefits that come with it. Jonathan was thorough and very knowledgeable about what was needed to service our unit and made sure that I understood what was needed and to contact them if anything should arise in the future. Great guy, good work and we’re very pleased with his professionalism.
