Our Quality Staff is Here to Help!

At Harker Controls, your new controls system installation is handled fully in-house. We do not subcontract out the installation work as many other controls contractors do. This allows for faster, higher quality installations. When you need changes made to the installation, we are able to react immediately, without waiting for a subcontractor to fit things into their schedules.


Harker Controls can provide you with a full turnkey project with product selection, system design, installation, startup and commissioning,or we can provide you with any combination of the services.


Harker Controls also provides installation assistance to customers that want to install the controls themselves. We can provide simple installation directions, extra installation manpower or startup/commissioning assistance.
