Raypak service
Service for the Raypak boiler you already have.
Raypak is headquartered in Oxnard, California, and its copper fin-tube and condensing boilers heat hospitals, hotels, campuses, and plants across the state. Scale on the heat exchanger, worn ignition parts, and tired controls are the usual service calls.
McKenna services and repairs Raypak boilers with its own crews. We don’t sell Raypak equipment, so the recommendation is what the boiler needs: a repair, an upgrade, or a replacement when the numbers say so.

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 Raypak 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 Raypak.
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.
