Controls Upgrades & Retrofits

Technology Saves Energy and Budgets Matter!  

At Casto, we understand that your control system may not be in great working order. Casto has the ability to upgrade and retrofit modern technology and equipment to your existing system.

Such as:

  • Pneumatic to Electronic Control
  • Upgrade to New Equipment
  • Valves
  • Control Boards
  • Sensors
  • Thermostats
  • Actuators
  • Pumps


One reason to upgrade!

By upgrading to a BAS system it gives Casto the ability to monitor your building remotely and allows us to prevent, diagnose and assist in solutions to problems without having to be onsite.  Therefore, saving down time and money for our clients.
