They will never arrive on time. All three times I have had to wait for them for the same problem they have been hours late. The appointments are set for between 8am and noon and the technician would never arrive before 2pm! They ordered four extra boxes of parts to be shipped to my house that I paid for and then they didn't even need to use them and told me I had to send them back myself if I wanted the refund for them, just horrible customer service. Then they left heavy oily old parts on my back deck to top it off! read full review »
