WanTech HVAC
Founded in 1992 by veteran technician James O’Connor, WanTech HVAC emerged from a niche need in the Chicago area: legacy HVAC systems that others refused to touch. With years of experience troubleshooting and repairing vintage units, James developed a reputation for sourcing rare parts and crafting custom solutions for hard-to-find equipment—especially old-model York chillers with obsolete control boards.
