Dre was the best tech! I was hesitant to schedule the service call. We change the filter and keep the furnace clean. I was pleasantly surprised to not only learn a lot about my furnace, but also gained a better understanding of auto setting to keep the furnace in better running condition, the humidifier settings, and he reset my temperature controls. He was knowledgable, professional, and very kind. Well worth the money- I would highly recommend . Great tech!!
