I contacted Jones Plumbing and Heating late in the evening on a Sunday as my heat would not shut off. Jones contacted me first thing in the morning and scheduled a service right away. Derek from Jones Service Plumbing and heating did a great job in explaining what was causing my heat to not shut off (stuck valve) and the repair needed. A replacement valve was installed and the system works great! Derek was very knowledgable and professional. I will definitely use Jones plumbing and Heating in the future!
