I received a call from them about a service deal…normally I say no thank you and hang up but I am glad I stayed on tg e line. They were offering a tune up of my acfurnace and water heater for a great price. The technician was friendly and full of info. He stayed for over an hour and cleaned all of our items. He made suggestions to improve usage. My only complaint is that he did not leave any pricing for the suggestions. But that’s ok…I will just call again when I am ready. Thank you for wonderful service..we will be using your company again
