James was the technician who listened, investigated, and gave us several options to cure the issue that were dependent upon what would fit in the price range. Most importantly, James spent the time to explain everything in detail and made sure all questions were answered. This is the second time I’ve used SouthPort. They are the right choice!!

I'm on the home maintenance program for plumbing and HVAC. I have been very happy with the service to date. There is always plenty of warning before they arrive and they do their business quickly, professionally, and efficiently. During my last visit they detected two faucet leaks which resulted in two new faucets (covered under lifetime warranty by the manufacturer).

We had a new furnace installed by Southport Home Services and had an excellent experience from start to finish. Our salesman, Adam, was very knowledgeable, personable, and easy to work with. He answered all of our questions and made the process stress-free during an already stressful time.
Our furnace broke, and the very next day the installation team was at our home replacing it. The staff was professional, respectful, and did a fantastic job. Everything was left spotless and looked great when they were done. We even felt completely comfortable leaving for the day while they worked in our home, which says a lot.
We truly appreciate the quick turnaround, quality work, and great customer service. Highly recommend Southport Home Services!

My experience started with a call to Southport for a second look opinion. They were highly recommended. The technician Tyler was able to find and explain the problem/s I was having with my 20 year old furnace and AC unit. He went over my options thoroughly, quickly set up a time for Justin to go over those options with necessary numbers, and the appointment was made for a new furnace and AC. The technicians Max, Diego and Aaron did a fantastic job with removal of my existing system and new installation. They treated me and my home with respect, paying great attention to detail. Max explained the process as they went along, making sure any question I had was answered. Nathan, the sales manager was even kind enough to stop and make sure I was happy with the whole process. The entire staff exceeded my expectations and were so professional, courteous and respectful, which is especially appreciated, as home repairs can be quite stressful. I highly recommend Southport.

Southport responded quickly and effectively in replacing our sump pump on the day of the storm on 4/17/2026 where our lower level of our home flooded. Both Alex and Andy responded. Despite not being on call, Andy responded as a neighbor and ensured that the sump pump got installed himself so that the overflow would stop and damage would be minimized. This included working in the midst of the water at 3am. I suspect the water damage and overall impact would have been exponentially worse if not for Andy’s dedication to solving the problem. I was out of town when this occurred and both my spouse and I are very grateful for Andy and Southport’s prompt emergency response. Approximately a week later we proceeded with installation of a battery backup. Thank you for the service and assistance in mitigating this very stressful and difficult situation.
