Daniel Huang was our service technician for a full gas fireplace clean and some electrical and ignition issues.
He showed up on time, and had the courtesy to arrive wearing an adequate mask — a rarity and very welcome in peak infection season. He had all the equipment needed to carry out a "leave no trace behind" service, and used it well.
His explanations were clear, and his work excellent and careful, with great attention to detail. I really couldn't ask for a better experience or a more competent technician.
