We've had Chris come in and help us in a jam multiple times over the years - at our rental and as well as our main residence. Chris is so easy to work with - not pushy and returns our calls quickly. Our heater died back in February and he came and installed a new heater within days. If that isn't customer service I don't know what is! We continue to call Chris as our go-to AC/Furnace guy as it doesn't get any better.
