Signs You Need Water Heater Services

Water heaters rarely fail without warning. Knowing what to look for can save you from a full breakdown and help you avoid water damage or wasted energy. Here are the most common signs it is time to call a professional.

  • No Hot Water: If your water heater is not producing hot water at all, something has failed inside the system and needs immediate attention.
  • Lukewarm or Inconsistent Temperatures: Water that never quite gets hot enough or fluctuates unexpectedly often points to a failing heating element or thermostat issue.
  • Rusty or Discolored Water: Brown or reddish water coming from your hot tap is a sign of corrosion inside the tank, which typically means the unit is nearing the end of its life.
  • Strange Noises: Popping, rumbling, or banging sounds from your water heater are usually caused by sediment buildup, which reduces efficiency and strains the system over time.
  • Leaks Around the Unit: Any pooling water near the base of your water heater is a serious concern and should be evaluated right away to prevent water damage.

Water Heater Repair and Replacement in Wausau

Not every water heater problem means you need a brand new unit. Sometimes a repair is all it takes to get things running properly again. Our NATE-certified technicians diagnose the issue accurately so you are not paying for more than you need.

That said, if your water heater is more than 10 to 12 years old, or if repairs are becoming frequent, replacing the unit often makes more financial sense in the long run. A newer system runs more efficiently, which can noticeably lower your monthly energy bills. We help you weigh the options honestly so you can make the right call for your home and your budget.

We install and service a wide range of water heater types, including traditional storage tank models and tankless on-demand systems. Tankless water heaters are a popular upgrade for Wausau homeowners looking to free up space and enjoy a continuous supply of hot water without keeping a large tank heated around the clock.

As part of our broader plumbing services, we also handle related issues that can affect your water heater’s performance, such as sediment in the lines or pressure problems. And if you are dealing with slow drains or backups at the same time, our drain cleaning services can address those issues during the same visit.

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!
