Air conditioning regular safety self-inspection has a coup
Summer is the time when air conditioners are used most frequently. Many people find that their home cooling isn’t as effective as it should be, and the noise from the unit has become louder. Is your air conditioner broken? Do you need to repair it? How can you accurately determine what’s wrong?
Symptom 1: The Air Conditioner Won't Turn On
Self-check steps: First, check if there's a power outage. Make sure the circuit breaker is on and the fuse hasn't blown. Confirm that the power switch is in the "on" position. Also, ensure the plug is properly inserted into the outlet. If all these are correct, the issue might be with the unit itself or the remote control.
Symptom 2: Unusual Noises
Self-check steps: Check if the unit is installed correctly and not tilted. Ensure it is securely mounted. Sometimes, the wall or surrounding structure can cause resonance, making the noise more noticeable. Also, make sure the front panel or grille is fully closed and not obstructed.
Symptom 3: Poor Cooling or Heating Performance
Self-check steps: Verify that the temperature settings are correct and the mode (cooling or heating) is properly selected. Check if the unit is appropriately sized for the room. A common issue is dirty air filters, which can reduce airflow and efficiency. Also, inspect the indoor and outdoor units for any blockages around the air intake or exhaust vents. Make sure the set temperature is reasonable. During peak electricity hours, voltage fluctuations can also affect performance. In cold weather, if the outside temperature drops below -7°C, heating may be less efficient. Similarly, if the outdoor unit is exposed to direct sunlight or the temperature exceeds 45°C, cooling performance may suffer.
