Air conditioner repairs can be costly, so it's essential to schedule regular maintenance with an accredited professional AC technician. It is also crucial to learn about the common problems you may encounter and take preventive measures to avoid unwanted problems.

Air Conditioner not Cooling Properly

Frequent complaints on air conditioners is that it is not cooling the room as expected. This can be caused by several factors:

• Clogged Air Filters
• Low Refrigerant Levels
• Dirty Evaporator or condenser Coils
• Faulty Thermostat

Solutions:

• Clean or Replace Air Filters: Dirty filters will block airflow and reduce the system’s efficiency. Clean or Replace them every 1-2 months.
• Check Refrigerant Levels: If refrigerant levels are low, there could be a leak. Contact a professional to inspect and recharge the system.
• Clean Coils: Dirt accumulation on coils reduces heat transfer, so clean them annually.
• Thermostat Calibration: Ensure the thermostat is set correctly and functioning. You may need to recalibrate or replace it if necessary.

Air Conditioner Making Noises

Unusual sounds like grinding, squealing, or banging are red flags that something is wrong. These noises could indicate:

• Loose parts
• Worn-out belts
• Motor issues
• Debris in the fan

Solutions:

• Tighten Loose Parts: If parts have come loose, they may rattle. Tighten screws and bolts where needed.
• Replace Worn Belts: A squealing noise usually signals a worn-out belt, which will need replacement.
• Lubricate or Replace Motor: Grinding sounds often come from a malfunctioning motor that might need lubrication or replacement.
• Clear Fan Obstructions: Check for any debris or objects that might be stuck in the fan or blower wheel.

AC Fan Is Not Working

If the fan is not working, the AC won’t be able to circulate air, which can lead to overheating. Possible causes include:

• Faulty fan motor
• Electrical issues
• Capacitor problems

Solution:

• Inspect Fan Motor: If the motor is faulty, it will need to be replaced.
• Check Electrical Connections: Ensure all wires are properly connected, and look for any signs of electrical damage.
• Replace the Capacitor: If the capacitor is dead, the fan won’t turn on. Replacing it should solve the issue.

Air Conditioner Leaking Water

Water leakage can occur inside or outside the house due to several issues

• Clogged condensate drain line
• Broken condensate pump
• Ice buildup on evaporator coils
• Incorrect installation

Solution:

• Clear Drain Line: Clean out the condensate line to ensure water flows out properly.
• Fix Condensate Pump: If the pump is malfunctioning, you might need to repair or replace it.
• Check for Ice Buildup: If ice forms on the coils, it could be due to low refrigerant or poor airflow. Turn off the AC and let the ice melt before addressing the cause.
• Ensure Proper Installation: If the unit is installed incorrectly, it may not drain properly. Check for a proper tilt or ask a technician to evaluate the setup.

AC Freezing Up

Your air conditioner can freeze up due to:

• Low refrigerant
• Poor airflow
• Dirty air filters or coils

Solutions:

• Check Airflow: Ensure that your air filters and vents are clean to prevent blockages.
• Recharge Refrigerant: If the refrigerant is low, a technician will need to locate the leak and recharge the system.
• Clean Evaporator Coils: Keeping the coils clean will help prevent freezing.
