Days later Anctil Heating debugged the problem to be a bad limit switch control board and flame sensor were fine. I spoke to Theresa on the phone after she left her creepy phone message. At first she had an attitude and was very unprofessional. I asked to speak to a manager, but she said she was a manager and was 2nd in line. After that she apologized and said that I would not be billed. Nevertheless an $82 bill came in the mail. I m now sitting with an $82 bill from Jacob. Their charge for an incorrect diagnosis after Theresa said that I would not be getting a bill. Grading: Price: F (Their cost was $600 based on an incorrect diagnosis Quality of their work: F (same as above). Responsiveness: D (It took them 2 days to schedule me, but I think it's the busy heat season) Punctuality: D (The scheduling person would not give a time window, sometime that day). Professionalism: F.
