Who we are
One company from design through service.
McKenna engineers boiler systems, builds the equipment in its own ASME shop, installs it, starts it up, and services it for the life of the plant. When something needs attention, you call one company.
We also service and repair other brands, so a plant with mixed equipment can use one company for all of it.
We aren’t always the lowest price. Plants choose McKenna when they want one company accountable for the equipment, the installation, and the service.
