First cold night in our new home and the furnace wouldn't kick on. Called CNO and they came the same day. Really nice guys, Charlie and Patrick, very thorough, very efficient. Turns out the thermostat hadn't been programmed properly. They fixed it, no problem, and charged a very fair price. We will definitely call CNO the next time we have HVAC issues. Highly recommended.
