AirGaard Fixes Mini-Split Leak in Boynton Beach Home

In July 2025, a Boynton Beach homeowner called AirGaard after discovering a refrigerant leak in their ductless mini-split AC. Air conditioning performance had noticeably decreased, and the indoor unit was forming frost near the evaporator coil—a classic sign of low refrigerant.

Step-by-step diagnosis & repair:

Leak detection: The NATE‑certified technician used UV dye and an electronic leak detector to pinpoint a small crack in the evaporator line.

System evacuation: After isolating the faulty section, the tech vacuumed the system to remove moisture and contaminants.

Leak repair & pressure test: The damaged line was brazed, and a nitrogen pressure test confirmed no further leaks.

Recharge & calibrate: The system was recharged with the precise refrigerant charge, and airflow/temperatures were adjusted for optimal cooling.

Within a few hours, the mini‑split was back to full efficiency, restoring reliable comfort during South Florida’s humid summer. The homeowner was impressed by AirGaard’s “prompt, knowledgeable, and courteous” service—as reflected in local reviews praising their fair pricing and quick response
