Mini Split AC Repair and Refrigerant Recharge in Georgetown, TX

June 9, 2026 — Georgetown, TX

When a ductless mini split stops cooling in the middle of a Central Texas summer, the space it serves goes from comfortable to unusable fast — and for a commercial operator, that can mean an unhappy staff, idle equipment, or customers walking back out the door. Setpoint Services was recently called out to a Georgetown facility where a rooftop-mounted mini split had lost its refrigerant charge and was no longer keeping up.

The Problem: A Mini Split That Stopped Cooling

The ductless system had gradually lost refrigerant charge, leaving it unable to hold temperature through the peak afternoon heat. Low charge on a mini split is rarely a simple “top it off” situation — refrigerant isn’t consumed, so a low system points to a leak or a compromised service connection that has to be found and corrected, not masked.

What Our Technicians Did

Rather than just adding refrigerant, our team worked the system end to end:

• Recovered the remaining refrigerant from the system per EPA guidelines
• Ran full diagnostics to confirm the condition of the circuit
• Repaired the service access points where charge was being lost
• Pulled a deep vacuum and held it to verify the circuit was sealed and leak-free
• Recharged the system with R-454B refrigerant to manufacturer specifications
• Started, tested, and monitored the system through a full cooling cycle

Vacuum integrity testing during evacuation confirmed the refrigeration circuit was sealed before any new refrigerant went in — the step that separates a lasting repair from one that fails again a few weeks later.

Why Charge and Vacuum Work Matter

A mini split that’s even slightly undercharged works harder, cools less, and runs up energy costs while shortening compressor life. Proper evacuation and an accurate charge are what keep a ductless system efficient and reliable:

• Correct refrigerant charge protects the compressor and holds rated capacity
• A verified vacuum pulls out moisture and non-condensables that cause corrosion and acid formation
• Confirmed pressures and saturation temperatures prove the system is actually performing, not just running

For operators relying on ductless units to cool offices, back-of-house areas, server closets, or small retail spaces, that difference shows up directly on the utility bill and in equipment lifespan.
