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.

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!
