 Trustindex verifies that the original source of the review is Google. Keith was brought in to resolve major issues with a very complicated residential system after numerous contractors had walked away from the project. He studied the system and came up with  cost effective and reliable solutions to make the system viable again. Keith could have sold an expensive replacement heating system ( low six figures were some quotes ) but he took the hard route and fixed the problems. And he has always been available to answer questions by text or call. His invoices were always fair and honest. I highly recommend his services.
