3. Low Refrigerant Levels

  • Symptoms: Reduced cooling and ice formation on the refrigerant lines.
  • Potential Cause: Typically due to a leak in the system, a situation requiring immediate professional attention.
  • Solution: Contact a professional to locate and repair the leak, followed by refrigerant top-up.

4. Faulty Compressor

  • Symptoms: Lack of cooling and loud noises from the outdoor unit.
  • Potential Cause: Electrical issues, refrigerant leaks, or overheating can cause compressor failure.
  • Solution: Due to its complexity, professional help is advised for diagnosing and addressing compressor problems.

7. Frozen Evaporator Coil

  • Symptoms: Reduced cooling and visible ice on the outdoor unit.
  • Potential Cause: Low refrigerant levels, poor airflow from dirty filters, or blocked return air ducts.
  • Solution: A professional should be contacted to address frozen evaporator coils, as they can cause significant damage to the system.

8. Fan Problems

  • Symptoms: Absence of air from the vents, loud noises from the unit.
  • Potential Cause: Issues could range from a faulty motor, worn-out belts to lack of lubrication.
  • Solution: Due to various potential causes, fan-related problems should be left to professionals.
