In the scorching heat of summer, a malfunctioning air conditioner can quickly turn your living space into an unbearable sauna. One common issue that perplexes many homeowners is when the AC’s fan is running, but the split AC refuses to cool the room adequately. Let’s dive into the intricacies of this problem and explore the possible causes behind it.
Understanding the Basics
Before delving into the reasons why your split AC might not be cooling despite the fan running, it’s essential to grasp the basics of how these systems operate. A split AC comprises two main units – the indoor unit with the evaporator coil and the outdoor unit containing the condenser and compressor. The fan plays a crucial role in circulating air, contributing to the cooling process.
Common Reasons for a Fan Running but No Cooling
Low Refrigerant Levels
Explanation: Inadequate refrigerant levels hinder the cooling process.
Solution: Professional inspection and refilling of refrigerant.
Dirty or Clogged Air Filters
Explanation: Restricted airflow due to dirty filters affects cooling efficiency.
Solution: Regularly clean or replace air filters as part of routine maintenance.
Issues with the Thermostat
Explanation: Incorrect thermostat settings can lead to improper cooling.
Solution: Calibrate the thermostat to the desired temperature.
