Greater San Antonio Recharge & Replacement Services

Refrigerant (often called “Freon” in older systems) is not a fuel that gets used up; if your system is low, it almost always means there is a leak. Simply adding refrigerant without fixing the leak is a temporary bandage and may violate regulations. In Greater San Antonio, we focus on safe, code-compliant freon service that addresses both leak repair and proper recharging.

Our recharge and replacement services can include:

  • AC refrigerant replacement: Safely removing remaining charge and replacing with the proper refrigerant type.
  • Freon recharge: Recharging systems that use older refrigerant only after leaks are located and repaired.
  • Freon replacement and freon installation: Upgrading or converting certain systems when feasible and appropriate.
  • System performance tuning: Adjusting charge to manufacturer specifications for best cooling efficiency.

We handle modern refrigerants as well as legacy Freon‑based systems where allowed, always following federal, state, and local rules for recovery and disposal.

When a recharge or refrigerant replacement may be appropriate:

  • You have had a verified leak repaired and need the system recharged.
  • Your system’s refrigerant was incorrectly charged by a previous provider.
  • A line, component, or evaporator coil replacement required evacuating the system.

Our goal is to ensure your system has the correct type and amount of refrigerant, not just “topping it off”, so you get consistent cooling performance in San Antonio, TX, without unnecessary strain on your compressor.
