RBI service
Service for the RBI boiler you already have.
RBI copper fin-tube and condensing boilers heat schools, offices, and plants across California. The heat exchanger, the ignition system, and the controls are where most RBI service happens.
McKenna services and repairs RBI boilers with its own crews. We don’t sell RBI equipment, so the recommendation is what the boiler needs: a repair, an upgrade, or a replacement when the numbers say so.

How an RBI service call runs.
01
Send the nameplate
Call or use the request form. A photo of the nameplate tells us the model, size, and pressure before we arrive.
02
Inspection
A McKenna technician inspects the boiler, burner, controls, and safety devices, and notes what needs work now and what can wait.
03
Written scope
You get a written scope and quote. Code repairs list the R stamp work and the inspector hold points.
04
Repair and test
McKenna does the work, tests the safety controls, tunes the burner, and hands you the paperwork.
Why McKenna
Why plants use McKenna on their RBI 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 RBI.
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.
