I highly recommend Wilmington Air! They have done my annual HVAC service call as well as a repair for me and both times it was a great experience. They answer the phone right away, are easy to schedule an appointment with, in my case were able to come right away all three times I've called them, the service techs are friendly, polite, clean, knowledgeable, patient and even took time to explain to me what they were doing. Afterwards, they called me to follow up to be sure I had had a good experience and was satisfied. From a customer service perspective, this is probably one of the best experiences I've had in Wilmington across all vendors. I highly recommend Wilmington Air!
