Dispatched for no heat. At arrival the system had no power. After check all power sources and switch. It was found to have a faulty door safety switch. Will order new switch. And reach out to schedule to install new part.

If I provided a positive or five star experience. I’d appreciate you sharing your thoughts in a review.
