      Trustindex verifies that the original source of the review is Google. The Furnace King team is nothing but the best I've ever seen. Courteous, competent and fast! Will never use another provider for my heating/cooling needs.

    Trustindex verifies that the original source of the review is Google. My furnace would not go above 67 degrees so I called furnace king. They were at my home within 4 hours and the service person did a thorough check. He immediately fixed a clogged waterline and we changed the furnace filters and it was back to normal. Very professional and expediate.

    Trustindex verifies that the original source of the review is Google. I had an issue with my hot-water -on -demand tank.  The technician came the very same day and spent several hours assessing the situation. Mohammed was excellent and fixed the problem.  He was extremely thorough and I am very happy with his work!!! Thank you .
