    Prompt and Polite and efficient. He explained what he checked on. He also asked if I had any questions or concerns. Kalin techs always have given me great service for 50 years. I highly recommend them. I have a service contract with them so this visit was prepaid. See annual service cost below

    Isaac was very nice, explained what he was doing and asked before doing anything that would cost extra. I do have to say that over the years all of the people who have come here were the same. Kalins seems to have a commitment to excellence.
    Response from the owner:Dear Carole,
