Barth Boiler LLC

Barth Boiler LLC operates as a specialized boiler service company in Hales Corners, Wisconsin, earning a perfect 5-star rating across 36 client reviews. Owner-operator Tom Barth runs the company, completing service calls himself rather than delegating to subcontractors. The business serves residential and light commercial clients throughout the Milwaukee metropolitan area, including neighboring communities in Waukesha and Racine counties. Weekend availability from 8 AM to 3 PM on Saturdays and Sundays accommodates homeowners who cannot pause their heating systems during weekdays.

What distinguishes Barth Boiler from broader HVAC contractors is the companys concentrated expertise in heating systems rather than cooling. The website lists boiler repair, installation, and troubleshooting alongside hot water heater installation, emergency heat service, oil burner tune-ups and repairs, and steam boiler cleaning. This focused specialization means Tom maintains deep technical knowledge of burner components, pressure controls, and zone heating systems that generalist technicians may only encounter occasionally. The business also offers Saturday and Sunday service hours, a practical convenience for households whose boilers fail overnight or at the start of a weekend.

Reviewers describe specific scenarios that illustrate the companys approach. Amira Rodriguez noted Tom diagnosed her boiler issue accurately, explained the problem clearly, and completed repairs before confirming safe operation. When a church congregation lost heat, Barth Boiler identified a faulty component that other contractors had misdiagnosed, saving the parish from an unnecessary replacement cost. Jesse Rodriguez described Tom as professional, knowledgeable, and thorough, arriving with the parts needed to complete the repair efficiently. Jennifer called the experience punctual, efficient, and friendly, emphasizing she would contact Tom for future work.
