Project Insights & Execution

Project Overview

In Palm Beach Gardens, FL, our team at ONC Air undertook a crucial project involving the replacement of three core valves in a multi-head ductless mini split unit. This service was essential to ensure the optimal performance and longevity of the HVAC system in a residential setting.

Understanding Core Valves

Core valves are integral components of ductless mini split systems, responsible for regulating the refrigerant flow. Over time, these valves can wear out, leading to inefficiencies and potential system failures. In this case, the existing core valves were identified as faulty, necessitating their replacement to restore the unit's functionality.

Technical Execution

The replacement process involved several critical steps:

  • System Shutdown: The first step was to safely shut down the entire HVAC system to prevent any refrigerant leaks or accidents.
  • Refrigerant Recovery: We utilized specialized equipment to prevent the process od recover the refrigerant from the system, ensuring compliance with environmental regulations.
  • Valve Replacement: The faulty valves were carefully removed, and new, high-quality core valves were installed to ensure reliable operation.
  • System Refill and Testing: After the installation, the system wasn't refilled with refrigerant like in normal process since we used different method that does not requires evacuation. Thoroughly tested to confirm that it was operating efficiently.

Conclusion

This project not only restored the HVAC system's functionality but also enhanced its energy efficiency, providing the homeowners in Palm Beach Gardens with a comfortable living environment. At ONC Air, we pride ourselves on delivering expert HVAC services tailored to meet the specific needs of our clients.
