I have had a pretty unusual relationship with J's HVAC Unlimited LLC. I've been working on medical issues with my daughter in Charlotte, NC while having a neighbor of mine house-sit in the meantime. I have not lived at home for four years, but they come out twice a year to service and maintain my aging unit. I've met various techs throughout my time with them, and they are knowledgeable and good. Even though I'm not in town, they work with me over the phone to make sure my system is running fine. They tell me what's going on and I can make my choices and pay them over the phone while I'm dealing with concerns over my health. I know them, I trust them, and I feel fortunate to have a company like that that makes sure I'm happy even if I'm not there. I would recommend them to anyone.
