Could not be happier with Jason and his assistant. I am wary of HVAC companies after many bad experiences, but this is the second time I’ve used Carolina in a short period of time and both times I’ve been more than pleased so the outstanding service is not a fluke! Jason’s knowledge of my particular unit was impressive and his attention to detail was second to none. On a personal note these guys were very personable and tolerated me looking over their shoulder as I am fascinated by tech stuff and their digital gauges and scales and precision was captivating. They explained every detail and answered all my questions.
