Johnson Controls Legacy Product Support

We provide continued parts support for end-of-life Johnson Controls building systems, including Metasys N2 series JCI DX Controllers, JCI AP Controllers, & JCI AS Controllers.

See the full list of Johnson Controls modules we currently support as well as the supported parts & sensors list.

Through our product repair program, our customers increase the life-cycle of their BAS equipment well beyond the OEM (original equipment manufacturer) EOL date. This saves customers thousands of dollars in potential upgrade spending and provides a safety net for their maintenance operation.

Repair vs. Replace

Cost Savings vs. New

On average, refurbishing controls cost 50% or less than the cost of new upgrades. This can can significantly reduce expenses for your facility budget or maintenance operation.

Equipment Life-Cycle

Refurbishing controls can extend the life-cycle of your equipment by 10 years or more! This allows you continued use of your system without the headache of a brand new install.
