Parker service
Service for the Parker boiler you already have.
Parker boilers are built in Los Angeles and run in laundries, dry cleaners, breweries, and food plants across California. They make steam fast for presses, ironers, and process loads.
McKenna services and repairs Parker boilers with its own crews. We don’t sell Parker equipment, so the recommendation is what the boiler needs: a repair, an upgrade, or a replacement when the numbers say so.

What we do
Parker work McKenna performs.
- Preventive maintenance and CSD-1 safety control testing, with a written report
- Combustion analysis and burner tuning to hold efficiency and emissions
- Tube bundle and coil replacement, with R stamp paperwork when the work involves welding
- Low water cutoff, safety valve, and pressure control testing and replacement
- Burner replacement and low NOx or ultra-low NOx upgrades selected to meet your air district’s NOx limit

You get a written scope and quote. Code repairs list the R stamp work and the inspector hold points.

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 Parker 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 Parker.
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 a Parker and a Cleaver-Brooks gets one service company and one set of records.
