I purchased my furnace from Southport and needed service when my AC went out during a storm. Andrew,my service tech was fantastic! He explained everything, got the parts the same day, and had me up and running in no time at all! At his recommendation, I also purchased a surge protector and maintenance agreement so I can rest easier during storms. Thank you Andrew!!

I was referred to Southport by a co-worker. Their staff is super friendly and informed. The sales manager Nate was reasonable to work with. You can probably save a few hundred bucks going with a smaller company with less overhead, but I think the peace of mind that comes along while working with an established company like Southport, is much more important. They got me booked for an instilation appointment within two days of signing a contract! Their technicians were polite and did the best they could at keeping my carpeted basement clear of mud, considering the first few hours they were there was during a rainstorm. Whatever mess they made they cleaned up. The installation took longer then expected (about 10 hours) but there was a lot of work to be done, and the technician thanked me for my patience. He said it's nice to be able to take their time and make sure everything is installed perfectly! All and all, I had a positive experience, and highly recommend using Southport. Friendly and fast service at fair price!

Justan and Luke did a great job on replacing our utility laundry sink and replacing our compression water valves to 1/4 turn valves.
They involved us in every step of the process to make sure they were doing it exactly as we wanted it done.

Justan was great! He explained exactly what he had to do and what it would cost for each step. When he found there was a shut off for that particular faucet he let me know and I didn’t pay to have one installed since it was already there. I appreciate the honesty and integrity! Was impressed with the service and signed up for a service plan with them that will bring in more savings for me. Thank you Justan and Southport Home Services!
