Signs You Need Boiler Service

Boilers are built to last, but they still need attention from time to time. What most homeowners don’t realize is that small issues often show up before a full breakdown. Catching them early can help you avoid bigger repairs, higher energy bills, and those miserable moments when the house just won’t warm up.

  • Uneven heating: If some rooms feel comfortable while others stay chilly, your boiler may not be circulating heat the way it should.

  • Strange noises: Banging, whistling, or gurgling sounds can point to pressure problems, trapped air, or worn parts inside the system.

  • Rising energy bills: Ever notice your heating costs creeping up even though your habits haven’t changed? An inefficient boiler may be working harder than necessary.

  • Water leaks or dripping: Moisture around the unit is never something to ignore and can signal a damaged seal, pressure issue, or internal problem.

  • Lack of reliable heat: If your boiler keeps shutting off, struggles to keep up, or leaves you without enough warmth, it’s time for professional service.

Boiler Repair

If your boiler stops heating properly, leaks water, or starts making unusual sounds, we’ll inspect the system and get to the root of the problem. Nobody wants to deal with a heating issue in the middle of a Wisconsin winter, so we focus on expert diagnostics and practical repairs that restore comfort as quickly as possible. Our fully stocked mobile warehouse helps us complete many repairs on the spot.

Boiler Installation & Replacement

Sometimes a repair makes sense. Sometimes replacement is the smarter long-term choice. If your boiler is older, breaks down often, or struggles to heat your home efficiently, we can help you choose a new system that fits your home, comfort needs, and budget. We’ll walk you through your options in plain language so you feel confident in the decision, not pressured by it.

Boiler Maintenance & Tune-Ups

Routine maintenance helps your boiler run more safely, efficiently, and reliably. A seasonal tune-up gives us the chance to check for wear, test performance, and catch issues before they turn into expensive surprises. Let’s be honest: you’ve got enough on your plate without worrying whether your heat will make it through the next cold stretch.

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.
