**Air Conditioner Service Call** **Work Performed:** - Responded to concern of evaporator coil freezing on an air conditioner installed in 2024. - Verified all furnace and fan functions — both operating normally with a clean filter. - Checked refrigerant levels and found them low. - Inspected system and observed an oil stain near the outdoor Schrader valve, suggesting a possible refrigerant leak. Tightened schrader valves. - Added leak sealant as a precaution and charged approximately 3 lbs of refrigerant to restore proper system levels. - System now operating normally. **Results:** - Possible leak at the outdoor Schrader valve or elsewhere in the system.(tightened, and inspected, no leak suspected after system recharge) - System stabilized after refrigerant top-up and sealant uv dye injection. **Recommendations:** - In the spring, schedule a full maintenance and leak search to confirm if the Schrader valve was the source of the leak or if further repairs are required.
