Boiler & Hydronic Heating Solutions

Since 1918, Keystone Heating & AC has been the region’s premier expert in hydronic heating! While many HVAC companies focus solely on forced-air furnaces, the Keystone team specializes in boilers, an efficient method of using water to carry heat exactly where it is needed most. Our services span the entire community, providing reliable warmth for single-family homes, bustling commercial offices, large-scale industrial plants, and essential municipal buildings like local schools and government facilities.

Boiler Repair and Installation from Keystone Heating & AC


Expert Boiler Repair and Diagnostics

If an existing boiler isn't working properly, it can be a frustrating and even dangerous experience for a homeowner to handle alone. At Keystone Heating & AC, we have years of experience fixing a wide range of problems, from leaking units that cause water damage to "kettling" and strange banging noises caused by sediment buildup. Whether your system is suffering from weak heating due to a pilot light issue or a complex pressure imbalance in a commercial office building, we find the solution. Our technicians are factory-trained on leading brands such as NTI, Burnham, and Weil-McLain, ensuring repairs for homes, schools, and industrial plants are done right the first time.


Professional Boiler Installation and Replacement

Choosing a new boiler is a critical investment in your property's efficiency. Our professional installers ensure your new system is properly sized and seamlessly integrated. We work with top brands like NTI, Crown, and Burnham, offering modern features such as Wi-Fi compatibility that allows you to control your heating system from a smartphone or tablet. We offer flexible installation models for cramped residential quarters as well as commercial-grade power systems designed for high-output industrial use. For our municipal and school clients, we can design cascading systems that ensure the building stays warm even if one unit requires maintenance.


Specialized Radiant Heat Repair

Radiant heating provides an unparalleled level of comfort, but keeping these systems well-maintained is critical for consistent warmth. If you are experiencing cold spots in your floors or leaks at the manifold, it is best to call for professional repair immediately. Our technicians can trace leaks and mechanical issues back to their source without unnecessary disruption to your property. We are skilled in servicing all types of radiant systems, from residential floor loops to heavy-duty hydronic setups in commercial warehouses and municipal garages, ensuring your heat is delivered securely and effectively.


Custom Radiant Heat Installation

Radiant floor heating has become a popular choice because, unlike furnaces that lose heat through leaky ductwork, piping is much more secure. By circulating warm water beneath the floor, we ensure every bit of heat is delivered where it is needed most. We offer versatile installation options for new construction and retrofits, including floor, wall, and ceiling heating. Because radiant heat warms objects and people directly, it is the ideal solution for large, open environments like industrial shops and municipal workshops. Keystone is proud to be the leading source for quality radiant floor heating contractors in Racine and Kenosha, handling installations from start to finish!


Comprehensive Radiant Floor Heating Service

To keep your radiant floor heating system running smoothly and efficiently, regular professional maintenance is essential. Over time, air pockets and sediment buildup can reduce efficiency and put unnecessary strain on your boiler. Our comprehensive service includes deep-cleaning the system, inspecting manifolds, and performing full hydronic flushes to remove mineral deposits. This preventative care is especially vital for high-traffic public buildings and schools where system reliability is non-negotiable. From a single residential bathroom to massive industrial floor slabs, we provide the maintenance necessary to protect your investment for decades!
