I had a problem develop on Monday evening and called and scheduled an appointment that night for a tech to come out on Tuesday. He arrived on time, was very polite and explained what he would be doing and all costs involved. It was a clogged line and he got the problem taken care of and I haven't had a problem after that this week. He also answered additional questions I had involving future work and the type of maintenance I should do on a regular basis to keep the lines cleared. His name was Josh and I was very pleased with the experience.
