After having another company tell me my unit was fried and needed to be replaced, I called Darville out to give a second opinion. In 10 minutes, the tech had found and fixed the problem. This company has a high level of integrity and concern for the people they serve. I will never use another HVAC company from this day forward. In this day and age, it is refreshing to find this high level of service and honesty! Thanks to Mark Darville for making me feel like I was the only customer you had!” – Donald Blankenship
