Boiler Repair & Hydronic Heating Service

Hydronic heating repair specialist


Every year, there are fewer and fewer companies in Waukesha and Washington County that are proficient at working on hydronic heating and boiler systems. The truth is, boiler systems are one of the most complicated heating systems out there. Loaded with complex controls, relays, mixing valves, all of the piping and all of the different ways a system can be configured, boilers are, in all reality, over the heads of the majority of HVAC technicians. We're not the majority of HVAC technicians.


This is why if you find yourself out of heat with a boiler or hydronic heating system, that repair should be trusted to a Boiler Guru™. For three generations and over 80 years in this business, we have earned a reputation as the go to resource for homes with hydronic heating and boiler systems by successfully solving thousands of hydronic heating issues in Washington and Waukesha County.

The Two Major Types of Gas Boilers:

Conventional Gas Boilers

These are also known as a standard boiler.  A standard boiler is comprised of a heat exchanger and burners.  The heat exchanger in a conventional boiler will likely be made of cast iron and will typically vent into a chimney with metal vent piping. Although a conventional gas boiler isn't very efficient (80% at best), it does offer the advantages of simplicity and longevity of service life.

Signs your hydronic system or boiler may need repair

Noise- A common symptom of a boiler system that isn't working quite right are strange noises coming from the system. In boilers, these can be banging pipes, gurgling or even slushing water through the system. If you notice your boiler making unknown noises, call to book boiler service today.


No heat to all or a part of the home- When your heat is out and you have a boiler, it's time to get service scheduled quickly. Sometimes when a home has hydronic heat, only part of the boiler system isn't working. This could be a control, boiler pump or zone valve issue. To diagnose a complete or partial no heat situation on your home's boiler system, call 262-367-3266 today.


Water leaks- Water is the key source of transferring heat to your home in a boiler or hydronic heating system. If you see water leaking from the boiler, piping, valves, pumps or any other part of the heating system, its best to get on the schedule for a boiler repair as soon as possible. Small boiler leaks can develop into large boiler leaks if left unrepaired. Call 262-367-3266 or book boiler pipe leak service here.
