Ductless Mini Splits in Wausau

Call Today... Relax Tonight

0.0 Google Rated

Central Wisconsin is no stranger to temperature extremes. Wausau winters can be brutally cold, and summers bring heat and humidity that can make certain rooms in your home feel unbearable. If you have a sunroom, a finished basement, a home addition, or a room that never seems to stay comfortable no matter what your main system does, a ductless mini split might be exactly what you need.

Unlike traditional heating and air conditioning systems that rely on ductwork running throughout your home, ductless mini splits deliver conditioned air directly to the spaces that need it most. No ducts required. That means faster installation, more targeted comfort, and the ability to control the temperature in individual rooms independently.

At Southport Plumbing, Heating & Cooling, our NATE-certified team installs and services ductless mini split systems throughout the Wausau area. Whether you are adding comfort to a space that lacks ductwork or looking for a more efficient way to heat and cool your home, we are ready to help. Contact us today to schedule a consultation and find out if a ductless mini split is the right fit for your home.

Benefits of Ductless Mini Splits

Ductless mini splits have become one of the most popular comfort upgrades for homeowners across Central Wisconsin, and for good reason. They solve problems that traditional systems simply cannot address as efficiently. Here is a look at why so many Wausau-area homeowners are making the switch:

  • Zoned Comfort Control: Each indoor unit operates independently, so you can heat or cool only the rooms you are actually using instead of conditioning your entire home at once.
  • No Ductwork Needed: Perfect for older homes, additions, garages, or any space where running new duct lines would be impractical or too costly.
  • Year-Round Efficiency: Most ductless systems function as heat pumps, providing both heating and cooling from a single unit, which can significantly reduce energy costs compared to running separate systems.
  • Quiet Operation: Mini splits are remarkably quiet compared to window units or forced-air systems, so you get comfort without the constant hum and noise.
  • Improved Indoor Air Quality: Without ductwork to collect dust, allergens, and debris, ductless systems can help maintain cleaner air in your living spaces.

Ductless Mini Split Installation and Service in Wausau

A ductless mini split system consists of two main components: an outdoor compressor unit and one or more indoor air-handling units mounted on the wall or ceiling. A small conduit connecting the two runs through a hole in the wall, which is far less invasive than installing an entire duct system. Most installations can be completed in a single day, meaning you are not left without comfort for long.

Our team helps you determine the right system size and configuration for your specific needs. A unit that is too small will struggle to keep up on the coldest and hottest days of the year, while one that is oversized can cycle on and off too frequently, wasting energy and reducing comfort. We take the time to assess your space and recommend a system that fits your home and your budget.

Ductless mini splits are also an excellent complement to existing whole-home systems. If your furnace handles the main living areas well but you have a bonus room above the garage or a workshop that never gets comfortable, a single-zone mini split can solve that problem without any major renovation. For homes looking at more comprehensive upgrades, our heat pump options offer another efficient path to whole-home comfort.

We service ductless systems from all major manufacturers and carry the parts and tools needed to handle most repairs on the spot. Whether you need a new installation in Schofield, a tune-up in Stratford, or a repair anywhere across the Wausau area, our fully equipped team is ready to get the job done right.

I had a boiler system installed by Southport and everyone I interacted with was fantastic! After several quotes I selected them because I thought the company had a lot of integrity. I first got a quote from Caleb who was most professional, walking me through all the options they had for me and being very reasonable on the pricing. They scheduled the installation within a week and, on that day, the technicians Ryan and Jacob were excellent and very hard workers. I appreciated that they were very careful inside the house, putting shoe protectors while upstairs and overall being very respectful. They stayed until the job was done and my heat was restored. I would highly recommend Southport if you need a new boiler installation or and work or maintenance on your boiler, home heat, or water heating system.

Thank you for sending Andrew Wenk to test our furnace. He could answer our questions clearly and tested all the important components and measured various pressures, temperatures, speeds, and other technical factors. He gave us 3 estimates for replacing parts that are needed due to age of the furnace. Andrew was pleasant and respectful to us.

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
