Why Your AC Is Running But Not Cooling

When your air conditioner is not cooling properly, it could be due to small, fixable issues or more serious internal faults. Ignoring the signs can:

  • Increase electricity bills
  • Strain the compressor and fan motor
  • Lead to costly HVAC repair or replacement

Understanding the cause is the first step to getting your comfort back.

Quick AC Troubleshooting Steps You Can Do Yourself

Before calling an AC technician, check these quick fixes:

Check the Thermostat Settings

In other cases the thermostat is switched to fan rather than cool. Ensure that it is turned to cool and the temperature is lower than the room temperature.

Inspect and Replace Dirty Air Filters

An air filter that is clogged will block the airflow, and your AC will not blow out cold air. Change or wash filters once a month or in six months.

Reset Circuit Breakers and Power Switches

If the circuit breaker is fall-down, your Air Conditioner may run without cooling. Reset it and make sure the power supply is stable. 

Reasons Your Air Conditioner is not cooling.

1. Low Refrigerant Levels or Refrigerant Leaks.

The substance that absorbs heat is referred to as refrigerant. Your AC will blow warm air when it is low or it is leaking. Refrigerant can only be checked and filled by a professional.

2. Developed Condenser/Evaporator Coils.

Coils that are not clean of dust do not allow good heat exchange, and so, they do not cool well. Coil cleaning to regain its performance is part of the regular AC maintenance.

3. Frozen Evaporator Coil

When your AC is operated continuously and the air flow is low, then there is a possibility that the evaporator coil will get covered with ice. Some of the causes are dirty filters, low refrigerant or airflow.

4. Ductwork Problems or Obstructions.

Leaky or blocked ducts decrease the airflow and some rooms become hot whereas other rooms remain cool. Central AC service includes duct inspection.

5. Broken Compressor or Fan Motor.

Even after cleaning and servicing, your AC still fails to cool, then it can be possible that the compressor or the fan motor is not functioning properly a symptom that you need to call an AC repairman.

When to Call a Professional for AC Repair

Not every issue is DIY-friendly. Call a certified HVAC technician if you notice:

  • Refrigerant leaks
  • Electrical issues or burning smell
  • Frozen coils that keep returning
  • Weak or no airflow despite filter replacement
  • Strange noises from the outdoor or indoor unit

Preventive AC Maintenance to Keep Your Unit Cooling

The best way to avoid costly air conditioner repair is through regular AC service and maintenance. Here’s a simple schedule:

·Monthly: Service filters or change filters.

·Quarterly: Clean drain lines, vents and coils.

·Every year: Book an expert AC service.

One major reason homeowners skip servicing is cost. But here’s the reality:

  • Minor fixes (filters, cleaning, thermostat reset):500 Rs. – 1,500 Rs.
  • Medium repairs (coil cleaning, drain, capacitor replacement): 2,000 Rs. – 5,000 Rs.
  • Major repairs (compressor, PCB board, fan motor): 8,000 Rs. – 15,000 Rs.
