Southport was extremely helpful and had an appointment the day after I called to inquire about their maintenance plans.

Luke was great. He explained what he found during routine furnace maintenance, things that were working well and things to watch for in the future. Best experience I have had in a long time.

I had a wonderful experience with Southport! Justin and Phil were both fantastic to work with. Justin was incredibly friendly, knowledgeable, and helpful throughout the entire process. He made everything easy and stress-free and was a pleasure to work with!
Phil was equally wonderful! He was professional and thorough. I really appreciated his attention to detail and the care he put into his work. Both Justin and Phil went above and beyond to provide excellent customer service.
I highly recommend Southport and especially Justin and Phil! Thank you both for such a positive experience!

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

Southport completed a furnace inspection and tuneup, and same day fixed a couple things that had come up in their review. Their staff is kind, friendly, consistent, informative, and knowledgeable. Their explanation was thorough and their reports showed they really did their due diligence. They take their time to answer questions and leave the homeowner feeling confident. Can’t recommend enough.

Tyler and Dakota installed our new A/C unit today. Right form the time they arrived (on time!) until they departed their professionalism, skills and gentlemanly manners never swayed. They are excellent representatives of Southport. More reasons why we use Southport exclusively! A job well done, Tyler and Dakota!

Andrew performed the annual plumbing inspection 2/20/2025. He is very knowledgeable and skilled in his work. He discovered a couple of situations that needed immediate attention. Those situations were promptly addressed and corrected. Like Tyler and Dakota Andrew is a stellar example of the excellent service from Southport!

On 10/22/2026, Tyler did the annual inspection on our furnace and found a couple concerns. He explained the situation and gave fair estimates. A great representative of Southport!

Also on 10/22/2026, Caleb stopped by abd presented estimates for replacing the furnace. He is very knowledgeable and presents all options very well. Another excellent representative of Southport!

On 10/23/2026 Service Technician Jacob performed the necessary repairs and cleaning of our furnace. Jacob is not extremely knowledgeable, he is personable and efficient. Definitely another outstanding representative of a great company. Well done, thank you!

Southport was exceptional from beginning to end. We had an unfortunate incident last week Wednesday that lead us to having to replace our Furnace.

After an emergency call to our local Fire Department in Caledonia and WE Energies, we reached out to Southport Home Services. They had a Technician out early the next morning to evaluate the issue, within minutes Nathan Simons called and was in our home explaining the many options that best fit our needs. He was very detailed, thorough, knowledgeable and displayed outstanding customer service.

The Technicians installed our new Furnace that next day. We are beyond pleased and thank you Southport for the fabulous Customer Service and explaining our options.

We highly recommend Southport to any and everyone looking for Five Star service!!

Many Thanks!

Sincerely Lynda & Mark Behringer
