Thomas Nelson Services is a family run business that strives to provide our customers with excellent service. We have been serving the Northern Virginia area for 26 years; established in 1989 by my father, Pat Nelson, and grandfather, Thomas Garretson, and now on to its third generation. As long as I can remember I’ve been helping my dad; from handing him a screwdriver when I was ten years old to becoming partners in business. I’ve watched how he has treated his customers and the friendships he’s made over the years and the hard work it takes to run a successful business. With the foundation that my father and grandfather have laid, I will continue to provide my customers with excellent hvac services they have come to know from my family.
