We’ve been keeping busy on the streets of the “Cheese Capital” long enough to know that a local home is only as comfortable as its mechanical systems. You’ve likely spotted our white trucks parked near the Rural Arts Museum or cruising past the historical marker downtown that honors Joseph Steinwand and the birth of Colby cheese. Whether we’re navigating the residential turns of the Clark County side or heading over the Marathon County line to help a neighbor, we know this area by heart. We understand that life here means preparing for the deep Central Wisconsin freezes that strain your furnace and the humid summer stretches that put your air conditioner to the test.

If your home’s essential systems need professional attention, reach out to schedule your service with our crew today.

I have a Shield maintenance agreement with Southport Plumbing Heading and Cooling.

The value for the plan is fantastic! They come out and help maintain your plumbing, heating and cooling systems. Jacob from the HVAC side has come out to my home and has done an excellent job of keeping me aware of what is working well, and what I may need to keep an eye on.

Justan and Nathan from the plumbing side have also come out to my house and did the regular yearly maintenance. They too, do an awesome job of keeping me updated on how the plumbing is within my house.

I also was alerted to the battery being bad for my sump pump backup system and Justan and Nathan installed a new sump pump and a new backup system as well. The timing was impeccable as we faced a power loss for around 24 hours, and the battery was fully charged and the backup sump pump worked while we didn't have power! It was better paying for the backup system than a repair bill for a flooded basement.

To round it out, the office staff, Sarah did a great job helping me coordinate not only the visits for the maintenance, but also helped facilitate the installation of the plumbing work.

They keep giving great reasons why I'm a long term Southport Plumbing, Heating & Cooling customer!

Thank you!

I recently had a technician from Southport come out to provide a quote for a new furnace and air conditioning unit, and I was very impressed with the experience. They did a thorough inspection to determine the best fit for my property rather than offering a one-size-fits-all solution.

Caleb, the representative, was knowledgeable and took the time to explain all of my options. He educated me throughout the entire process, and made sure I understood the differences between each system so I could make an informed decision. The customer service was truly superb.

I would definitely recommend Southport to anyone looking for an honest, professional HVAC company. They primarily carry Carrier equipment but they do other options exclusively made by Carrier for Southport as well.

Tommy and Blake were so helpful. They went out of their way to explain everything throughly and left me with clear documentation on my issue as well as a full Plumbing System Evaluation. I received 3 different price structures and ways to save money. I would highly recommend this company! Thank you ever so much!

If you want WOW service, contact Southport! From my first call to schedule an emergency air conditioner unit replacement to the installation, Southport was professional, prompt, and priced fairly. (I originally called another company who was the complete opposite--Southport, however, fixed the issue and made sure I was completely satisfied!)
