South Milwaukee's well-built older homes depend on boilers for comfortable winter heat — and a boiler failure during a Wisconsin cold snap requires fast, skilled response. Burkhardt Heating, Cooling, Plumbing & Electric provides same-day boiler repair service to South Milwaukee homeowners whenever possible, backed by 60+ years of Milwaukee-area heating expertise.
Our NATE-certified technicians service and repair all residential boiler types and brands: gas and oil hot water boilers, one- and two-pipe steam systems, combi boilers, and hydronic radiant heating systems. We diagnose and repair ignition failures, pilot light issues, low or high pressure conditions, circulator pump failures, zone valve faults, expansion tank problems, and leaking components.
Many South Milwaukee homes were built before World War II and may have original or older-generation cast-iron boilers in their basements. These systems can be remarkably durable, but they require knowledgeable technicians who understand steam and hot water system dynamics — not just modern furnace experience. Our team has both.
Burkhardt is a third-generation family business with deep roots in the Milwaukee area. We've earned our reputation by telling customers the truth: when a boiler can be repaired economically, we fix it; when replacement makes more sense, we say so and explain why. You always get an honest answer from Burkhardt.
GreenSky financing is available. Call Burkhardt at 414-206-3049 for boiler repair in South Milwaukee.
**FAQs**
**Q: My South Milwaukee boiler's pilot light won't stay lit. What's typically the cause?** A: A pilot that won't hold is usually a failed thermocouple — a safety component that senses the pilot flame and allows the gas valve to remain open. It's a straightforward repair in most cases.
**Q: My boiler fires up but the house doesn't warm up. What should I check?** A: Check that your thermostat is calling for heat correctly and that all zone valves are opening. If the boiler is firing but heat isn't reaching rooms, circulator pump failure or closed zone valves are common causes — both within our repair scope.
