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.

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!
