Southport’s Technician , Phil Lloyd, is a true asset to his organization! My wife, Karyn and I have had many contractors come through our house over the years and I would put Southport at the very top of our service partners. They are knowledgeable, reasonable, and most importantly trustworthy. Phil Lloyd took the time to share, in layman’s terms, the root cause of our problem and a remedy that would bring our system back up and running; peace of mind to our family. I would highly recommend Southport, and would give Phil Lloyd a 10 out of 10 related to Service, quality, and most important trust. Southport is fair on cost,I plan on partnering with Southport for many years to come. Jim Sheehan
