Boiler repair
Which kind of repair your boiler needs.
Most repairs are routine: a burner that won’t light, a feedwater pump that can’t keep up, a low water cutoff that keeps tripping. Some can’t wait for a scheduled visit. Some touch the pressure parts, which brings in the Authorized Inspector and the National Board R paperwork.
McKenna handles all four kinds below with its own technicians, boilermakers, and engineers, on McKenna boilers and other brands.
What we repair
Boiler repairs we make.
- Burner, flame safeguard, and gas train repair on Autoflame and other manufacturers' controls
- Low water cutoff, feedwater pump, and level control repair
- Tube leaks: single tubes replaced, or a full retube
- Welded pressure-part repairs under our National Board R certificate
- Refractory repair on rear doors, front doors, burner throats, and target walls
- Safety and relief valves replaced; McKenna sells Kunkle valves
- Repairs called out on your annual inspection report
- Combustion tuning after the repair, so the boiler stays within its air permit
Four kinds of boiler repair
| Repair | What it covers | Code paperwork | Where to go |
|---|---|---|---|
| Service repair | Burners, controls, flame safeguards, gas trains, feedwater pumps, low water cutoffs, refractory, gaskets, and valves | Usually none. Your service report documents the work. | Combustion Tuning & Burner Service; Refractory Repair |
| Emergency repair | A boiler that's down, a low water cutoff trip, a tube leak, or a flame failure, day or night | Depends on the repair | 24/7 Emergency Services |
| R-stamp code repair | Welded repairs and alterations to shells, furnaces, heads, tubesheets, and nozzles | Inspector authorizes and accepts the work. R-1 (repair) or R-2 (alteration) registered with the National Board. | R-Stamp Code Repair |
| Retube | A few bad tubes or a full retube, plus new tubesheets drawn and built in our shop | Rolled and beaded tubes: usually not an R stamp repair; check with your Authorized Inspector. Welded tubes and tubesheets: R stamp repair. | Retubes & Tube Repair |

How a repair runs
How a repair call runs.
01
Call or send the nameplate
Call (323) 987-1816 or use Request Service. Tell us what the boiler is doing, any lockout codes, and send a nameplate photo.
02
Diagnose on site
A McKenna technician traces the problem to its cause: burner, controls, feedwater, fuel train, or the pressure vessel.
03
Repair
Parts from our shelf, a written quote for larger work, and the Authorized Inspector involved when the repair is a code repair.
04
Paperwork and follow-up
The R form is filed when the job needs one. Our office follows up and schedules any work still open.
Repair or replace
When a repair isn't worth making.
If the shell, furnace, and tubesheets are sound, a repair or retube is usually the better value. If they’re wasted or cracked, a new boiler can cost less over the years you plan to run it.
McKenna builds boilers, so you get both quotes from one company. If you replace, a rental boiler can carry the load until the new one is in. For boilers of 2,000,000 Btu/hr or less in South Coast AQMD, check the Rule 1146.2 dates first.
