Why is the air conditioner not cooling or heating properly?
If your air conditioner is not cooling or heating properly, it may be due to several common causes related to system settings, airflow, or maintenance. Aurashu recommends following these key checks before requesting service, as many performance issues can be quickly resolved through basic inspection and adjustment.
1. Verify Temperature Settings and Mode
Ensure the unit is set to the correct mode — “Cool” for cooling or “Heat” for heating — and that the temperature setpoint is several degrees lower (for cooling) or higher (for heating) than the room temperature. Incorrect mode or mild temperature difference may prevent the system from activating fully.
2. Check Airflow and Filters
Clogged or dirty air filters restrict airflow, reducing cooling and heating efficiency. Clean or replace filters regularly, ideally every 2–4 weeks during heavy use. Blocked vents or return grilles should also be cleared for proper air circulation.
3. Inspect Doors and Windows
Poor insulation, open windows, or air leaks can cause conditioned air to escape, forcing the system to work harder and reducing performance. Make sure all windows and doors are properly sealed when the unit is running.
4. Monitor Outdoor Unit Condition
For systems with outdoor condensers, ensure the outdoor coil is free of dust, leaves, or debris that can obstruct heat exchange. Adequate ventilation around the outdoor unit is crucial for stable cooling and heating capacity.
5. Check for Refrigerant or Sensor Issues
Low refrigerant levels, faulty sensors, or electronic control errors can reduce performance. These conditions require professional inspection — contact Aurashu service if cooling or heating is persistently weak despite proper settings.
6. Environmental and Load Factors
Extreme outdoor temperatures or unusually large indoor loads (many people or devices generating heat) can temporarily affect performance. The system will adjust gradually to restore balance.
7. Maintenance and Preventive Care
Regular maintenance, including coil cleaning, refrigerant checks, and software updates, ensures long-term efficiency. Aurashu recommends comprehensive servicing every 6–12 months for optimal operation.
Summary:
Improper cooling or heating is often caused by incorrect settings, dirty filters, airflow blockage, or maintenance neglect. Check these first, and contact Aurashu if the issue persists for expert diagnosis and adjustment.
