ISO 9000 is a family of international standards for quality management. These standards cover everything from design and production to procurement and delivery processes.

In today's competitive world, when many claims to quality are unfounded, the ISO 9000 designation offers an assurance that the manufacturer follows a rigorous and tested process, with the goal of producing products that consistently meet customer requirements.

Lennox was the first manufacturer in the HVAC industry to structure its facilities to meet stringent ISO-9000 requirements. Every component we use is subjected to the scrutiny of our vendor-rating product. We run-test each unit that comes off our line, and we check products offline as frequently as every hour to ensure the highest standards of performance are met.

Our commitment to quality manufacturing not only helps us deliver reliability with every product we build, it also helps create a better comfort experience. Better means safer. It also means smarter products that help people enjoy their homes, without adding complication to their lives.
