American Exchanger Services, Inc

American Exchanger Services operates from Hartford, Wisconsin, serving industrial clients in the power generation and pulp and paper sectors. With a 1-star rating from 2 customer reviews, the company maintains a limited local presence at 709 W Wisconsin St and a machining center at 1950 Innovation Way in Hartford. Business hours run Monday through Friday from 7 AM to 4 PM, with delivery window concluding at 3 PM. The company trades as AmX and focuses on heat transfer equipment rather than typical residential HVAC systems.

AmX differentiates itself through four decades of specialized engineering experience in manufacturing and servicing shell-and-tube heat exchangers, feedwater heaters, and main steam condensers. Their vertical integration spans from initial engineering through final installation, supporting critical outage situations across diverse geographic regions. The company maintains a global service footprint extending from the Midwest to Malaysia, with field crews capable of installing, repairing, and retubing various heat exchanger configurations on short notice.

Both published reviews express significant dissatisfaction. One reviewer from Kingsway Instruments describes communication as nearly impossible and advises against using the company. Another reviewer, John Dorrer, questions whether the business remains operational. No technicians are named in either review, and no specific service scenarios or resolution details emerge from the available feedback.
