Call Today... Relax Tonight

4.8 Google Rated

When summer heat and humidity settle into Wausau, a dependable cooling system matters fast. Central Wisconsin weather can shift in a hurry, and older homes along with newer builds often have the same problem when temperatures climb: hot rooms, sticky air, and an AC unit that just cannot keep up.

Southport Plumbing, Heating & Cooling provides air conditioning service in Wausau for homeowners who want real comfort, not temporary relief. Whether your system needs a tune-up, a repair, or a closer look before it quits altogether, our NATE-certified technicians are ready with skilled diagnostics and fully stocked service vehicles. We also help homeowners compare options like ductless mini splits and heat pumps when a standard central air setup is not the best fit.

We know how frustrating it is when your house feels warmer than it should, especially during a humid stretch. If you are in Wausau or nearby communities like Schofield or Stratford, call today to schedule air conditioning service and get your comfort back on track.

Signs You Need Air Conditioning Service

Your air conditioner will usually give you warning signs before it fails completely. Knowing what to look for can save you from an uncomfortable breakdown during a heat wave and help you avoid more costly repairs down the road.

  • Warm or Weak Airflow: If your vents are blowing air that feels lukewarm or the airflow seems weaker than usual, your system may have a refrigerant issue, a failing compressor, or a clogged air filter that’s restricting performance.

  • Unusual Noises: Rattling, grinding, squealing, or banging sounds coming from your AC unit are never normal. These sounds often point to loose components, worn belts, or motor issues that need attention before they cause bigger damage.

  • Frequent Cycling or Running Constantly: An air conditioner that short-cycles (turns on and off rapidly) or runs nonstop without reaching your set temperature is working harder than it should, driving up your energy bills and wearing out the system prematurely.

  • High Humidity Indoors: Your cooling system plays a role in managing indoor moisture. If your home feels sticky or clammy even when the AC is running, the system may not be dehumidifying effectively, which is a common complaint during Central Wisconsin’s humid summers.

  • Rising Energy Bills: Ever notice your energy bills creeping up without a clear reason? An inefficient or struggling air conditioner is often the culprit. A system that’s overdue for service has to work harder to deliver the same level of cooling.

Air Conditioning Services in Wausau & Central Wisconsin

Air conditioning service covers a broad range of work, and the right solution depends entirely on what your system needs. At Southport Plumbing, Heating & Cooling, our process starts with a thorough diagnostic evaluation. Our NATE-certified technicians don’t guess. They use professional tools and hands-on expertise to pinpoint exactly what’s going on with your cooling system before recommending any repairs.

AC Repair

From refrigerant recharges and capacitor replacements to fixing frozen evaporator coils and repairing electrical components, our team handles the full spectrum of air conditioner repairs. Because our technicians arrive in fully loaded service vehicles, we carry the parts needed for most common repairs right on the truck. That means fewer delays and faster resolutions for you.

AC Maintenance & Tune-Ups

Preventive maintenance is one of the smartest investments you can make in your home comfort system. A seasonal tune-up includes cleaning the condenser coils, checking refrigerant levels, inspecting electrical connections, lubricating moving parts, and testing overall system performance. Regular maintenance extends equipment life, improves efficiency, and helps you catch small problems before they become expensive ones.

AC System Replacement

Sometimes a repair isn’t the most cost-effective path forward. If your system is more than 10 to 15 years old, requires frequent repairs, or simply can’t keep your home comfortable anymore, replacement may be the smarter long-term choice. We’ll walk you through your options honestly and help you select a system sized and configured for your home’s specific needs.

If you’re also exploring alternatives to traditional central air, we offer ductless mini split systems for homes without existing ductwork or for targeted room-by-room cooling. For year-round efficiency, our team can also discuss heat pump solutions that handle both heating and cooling in a single system. And when the seasons turn and you need to think about your home heating, we’re ready to help with that too.

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

We just replaced our entire HVAC system and Hot Water Heater this week with Southport...and we could not be happier!! Our previous system was working but was old...and Southport was able to come out IMMEDIATELY...even during this severe cold snap!! Starting with Nate, who came out to inspect, estimate the job and oversee it...to out technicians, Ryan, Casey and Jackson, these guys ROCKED!!! They were super polite...super efficient...super informative and they left the work area amazingly cleaned up! They were creative in accomplishing an off the beaten road request that we made and everything is in order. When you need HVAC work done...LOOK NO FURTHER!!!

10/22/26: So due Operator error, (or as I say, owner stupidity…LOL…😜), I called regarding a stuck button on my 8 year old electronic thermostat. We scheduled an appointment with SOUTHPORT and Tyler S. was just here and I was told something I probably already knew, (apparently). The button on the thermostat is ALWAYS-that way because the entire thing runs on a TOUCH SCREEN!!!! DUH!!!!
The visit was awesome and Tyler and his mentor giggled with me and DID NOT make me feel stupid at all!! Excellent customer service, from scheduling the appointment (same day) through the end of the appointment. Thank you Tyler and alllof the Southport staff!!!

I want to give a shout out to HVAC technician Vincent Beyer who provided much more than a simple routine check of my furnace. For example, he went through a list of suggestions to make my unit last longer, operate safer, and improve its efficiency. He explained technical items in ways that I could understand their need and how they operated within the whole system. We finished his visit by sitting down and covering every point we had discussed to make sure I understood and was comfortable with all the options and details.

In my opinion, you couldn't have a finer representative for your company.

I had my annual furnace/heat pump checkup this morning. Abraham Celis was the HVAC technician. He comleted a very thorough inspection and went over the results completely with me. Abraham took the time to insure the checkup was done in a quality manner, not just rushing to complete the job and to get to his next stop. I was impressed with Abraham's friendliness and professionalism. Another job well done by Southport.
I had my annual Heat Pump AC checkup today (8/26/26) by Southport. As always, their technician Zach Birkholrz did a thorough and excellent job. Zach is very pleasant and professional and explains the checkup process and results very clearly. And, as a bonus, he gets along with our dog.

Joe Suchla replaced our two outside faucets and main water shut-off today. The rear faucet was only accessible from a basement crawl space, so he installed a secondary shut-off valve in the baseme t so I did not have to enter the crawl space to shut off the faucet in the winter months. He also bought the main water shut-off up to code with a shut-off valve on each side of the meter. Joe arrived on time, performed all plumbing upgrades professionally, kept me informed of the upgrade progress, and cleaned up at the end of the job. We are very pleased with the job Joe did and have always been pleased with the work Southport has done for our plumbing and HVAC needs. We highly recommend Southport.

Jackson did an excellent job of system check of our AC. He explained everything he checked and the meaning of all test results. A very friendly and professional service tech. Highly recommend SouthPort and Jackson.
