Travis was very responsive and knowledgeable about the problem. Our dryer was smelling like smoke and we were diligent about cleaning the lint filter. We scheduled a service call with Horizon Home Services and Travis came out that day, diagnosed, and repaired the problem, which was 15 years of lint that had built up within the ducts of our dryer. I was shocked to see the amount of lint, and learned a valuable lesson : schedule preventative cleaning of the internal ducts of your dryer every 2-3 years. Thank you Travis!!
