Bryan service
Service for the Bryan boiler you already have.
Bryan has built watertube steam and hot water boilers in Indiana since 1916. Bryan boilers run in schools, hospitals, and plants across California, and the tubes, burner, and controls are where most service happens.
McKenna services and repairs Bryan boilers with its own crews. We don’t sell Bryan equipment, so the recommendation is what the boiler needs: a repair, a retrofit, or a replacement when the numbers say so.
What we do
Bryan work McKenna performs.
- Preventive maintenance and CSD-1 safety control testing, with a written report

Why McKenna
Why plants use McKenna on their Bryan boilers.
Independent
McKenna isn’t tied to a manufacturer’s rep agreement. We recommend what fits your plant, including keeping the boiler you have.
We build boilers
McKenna engineers and builds boilers in its own ASME code shop. That’s the same knowledge we bring to your Bryan.
Code repairs in-house
McKenna holds the National Board R certificate, so welded tube repairs and other pressure part repairs don’t need another company.
One company for the boiler room
We service and repair other brands too. A plant with more than one brand of boiler gets one service company and one set of records.

Yes. McKenna Boiler Works, Inc. replaces tubes on Bryan watertube boilers. When the tube work involves welding, McKenna makes the repair under its National Board R certificate per the NBIC, and you get the code paperwork your inspector needs. McKenna also notes the water-side condition behind a tube failure so you can review it with your water treatment company; McKenna is not a water treatment company.
