I called and scheduled an appointment after buying the special on Angieslist. Prior to the appointment, I was contacted to have a serviceman review the work to be done. He was on time (also they always call you just before they arrive) and professional. He looked over the jobs and told me that the 2 hours I purchased should cover it. When the appointment time came, the serviceman was on time, clean and prepared to do the work. He did all the work in the 2 hours, just like he said. I was impressed, so I called and asked for an appointment for my heater/its exhaust vent to be repaired (a home inspection had found several hazards). When the appointment time came, the serviceman was on time. He fixed most the heater problems, but told me the exhaust vent needed a complete replacement to be safe/meet code. Since I had told them that I needed the exhaust repaired (and not replaced), he told that he would need to get additional tools and parts. He showed me the amateurish/Rube Goldberg exhaust vent system and I had to agreed. He came back a few days later (on time) and cut/installed a new vent into the roof and finished the job. Both servicemen that I encountered were clean, well mannered and knew their trades. They cleaned up after themselves and left everything as they had found it (except for the problems).
