The service tech was Mario and he did a great job. He reviewed what he had done and gave me a good report on the condition of my older furnace and what some of my options would be if I want to replace it in a couple of years.. It was obvious from his comments that he knew what he was doing. He was very courteous, knowledgeable, no hype or pressure. He called to let me know he was en-route and arrived on time. Linda in the office was also very helpful in setting up the initial appointment and helping me reschedule it. This is the first time I have used Andy's and I will certainly use them again.
