What Should I Do If My AC Is Running But Not Cooling?

If your AC is running but not cooling, try a few quick checks, then schedule service if it persists. Gold Star repairs central AC and ductless systems, including refrigerant leaks, compressors, fans, capacitors, and thermostats.

• Set thermostat to Cool and 3–5°F below room temp.
• Replace or clean the HVAC filter.
• Make sure vents and the outdoor unit are not blocked.
• If you see ice on lines or water at the air handler, turn the system off.
• Ongoing warm air or weak airflow needs a professional. 24/7 emergency service available in Nassau County.
