Common Reasons Why Your Air Conditioner Isn’t Cooling and How to Fix Them:

Check the Temperature on the Thermostat



Ensure the thermostat is set to cool. If the settings were accidentally changed, turn the thermostat to heat and then back to cool. After a few minutes, check if cold air is blowing from the registers.

Dirty Air Filter

A clogged air filter obstructs airflow and impacts the thermostat’s performance.

Solution:

Inspect and replace the air filter if needed. Regularly check your filters to maintain proper airflow.

Dirty Outside Unit

The condenser (outside unit) condenses hot air into cool air. Dirt and debris can obstruct heat transfer.

Solution:

Clean the condenser and remove any weeds or dirt around it. Regular maintenance can prevent high repair costs.

Low Refrigerant Level

Insufficient refrigerant can prevent proper cooling. This may indicate a leak.

Solution:

Look for signs like ice buildup or hissing noises. Contact a professional for repairs and refrigerant recharging.

Frozen Evaporator Coil

The evaporator coil removes heat and humidity from the air. Freezing can hinder its performance.

Solution:

Addressing a frozen coil is complex. Contact a licensed HVAC technician to fix the issue and perform any required air duct cleaning.

Compressor Failure

A faulty compressor cannot cool air effectively.

Solution:

Replace the damaged compressor. It’s best to hire a professional technician for this task.
