QUICK ANSWER
McKenna Boiler Works, Inc. services and repairs boilers from other manufacturers for plants across California. That includes Cleaver-Brooks, Parker, Superior, Hurst, Fulton, Victory Energy, Bryan, Raypak, Lochinvar, AERCO, and more. McKenna’s own crews handle preventive maintenance, CSD-1 safety testing, combustion tuning, retubes and tube bundle replacement, burner and controls repair, and code repairs under the National Board R certificate. McKenna is independent, not a dealer for any of these brands, and builds its own boilers in an ASME code shop in Oceanside, California. Call (323) 987-1816 or email info@mckennaboiler.com.
Other brands
One service company for a mixed boiler room.
Most plants don’t run one brand. A Cleaver-Brooks firetube on process steam, a Parker on hot water, and a bank of condensing boilers on building heat can all sit in the same room. McKenna services all of them under one schedule and one set of reports.
Because McKenna builds boilers, our crews know pressure parts, burners, and controls from the shop floor up. Because we don’t sell these brands, the recommendation is what the boiler needs: a repair, an upgrade, or a replacement when the numbers say so.
