Understanding Hydronic Systems

In addition to our heating services, we specialize in hydronic heating systems, a highly efficient heating method that utilizes water as the heat transfer medium. Hydronic systems circulate heated water through pipes, radiators, or radiant floor heating systems. This technology offers several benefits, including even heat distribution, improved energy efficiency, reduced allergens, and quiet operation. Our experts are well-versed in hydronic systems and can assist you with installations, repairs, and maintenance.

Boiler Repair & Installation in Southeastern Wisconsin

When it comes to keeping your home warm and comfortable during Wisconsin’s coldest months, you need a heating company you can trust. At South Shore Heating, Air Conditioning, & Hydronic, we proudly serve homeowners throughout Southeastern Wisconsin, including Washington, Milwaukee, Ozaukee, Waukesha, Sheboygan, Dodge, Racine, and Fond du Lac Counties.


While gas and electric furnaces are some of the most common heating systems in homes today, they are not the only option. Many older homes throughout the region rely on boiler systems for


dependable, consistent heat. Boilers work by converting water into steam or hot water and distributing it through pipes to radiators, baseboard units, or radiant floor systems.


If your boiler isn’t performing as it should, our experienced team is here to help.

South Shore responded quickly when I had a problem with an air conditioning unit. They fixed both the problem I reported and another issue that they discovered. Service was quick, friendly, and reasonable.

Dylan correctly diagnosed the problem with my furnace and made the necessary repairs very quickly. While I was not planning on having to have my furnace serviced, I was very grateful he was able to come on a Saturday before I ended up without heat
