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.

Phil was outstanding! He diagnosed a problem that several other techs from a different company couldn’t figure out. He was so friendly and took the time to explain everything clearly. Highly recommend Phil from Southport!

Great experience on updating our HVAC systems to heat pumps/backup furnaces.
Ryan, Oliver, Andrew and Jacob (all installers for Southport) are wonderful, competent, and delightful young folks, who gave great service doing the physical upgrade of 2 older heat/ac systems.

I highly recommend Southport for your future HVAC upgrades. All the folks from the person doing the bids (Adam) to Manager (Jackson) to all the installers, are first class, professional and proud of where they work and what they do.

Losing AC in hot weather is never fun, but Southport made the whole process as painless as possible. They were quick to respond, easy to work with, and got everything moving fast when we really needed it.

From the initial quote to the installation of our new AC and furnace, everyone was friendly, knowledgeable, and professional. The communication was great, the work was done efficiently, and everything went smoothly.

We're extremely happy with the result and wouldn't hesitate to recommend them to anyone looking for HVAC work.

Got a furnace replacement and a/c unit install. Both work great. The hvac techs worked very hard but they were not so thrilled to be doing a full install on a friday. they made it clear by complaining within earshot for the whole 7 hours. So maybe consider not scheduling with them on a Friday and it may be a better experience for you. 5 stars

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!
