 Trustindex verifies that the original source of the review is Google. Thomas and David are the best!  Very reliable and very, very competent - they know their stuff.  David installed our AC system over five years ago -- quite a complex job and has been maintaining it ever since.  His son, Thomas is now in the business and is equally smart and reliable.  Always on time (if not 15 minutes early).  They do not commit to work they cannot deliver. Their prices are always fair and honest. Most importantly, they are kind and honest people. I have recommended them to two of my closest friends that have the same assessment of their work.

 Trustindex verifies that the original source of the review is Google. Highly recommend Southern X Services Group! I was hesitant at first after past experiences with other contractors, but Tom was professional, punctual, and did a top quality job installing our air con. Honest, reliable, and easy to deal with, wouldn’t go anywhere else.
