We called Fahrenheit because of a gas smell in our basement. They sent a young technician out once, who determined it was a "venting issue," ordered the wrong part, came back tried to install said wrong part, then returned again with the correct part and installed it. All for over $1000. The gas smell never went away but the tech claimed there was absolutely no leak. We called CNG who came out immediately, said there was a gas leak in a valve creating a safety issue, and charged us $300 for a simple and quick fix. A total waste of $1,000 and potential risk to our family's safety thanks to the incompetency of the Fahrenheit technicians. Based on other reviews I don't know how they are still in business. AVOID.
