Check Your Air Filter
A dirty air filter is one of the most common causes of AC problems. A clogged filter restricts airflow, causing your unit to work harder and less efficiently. Replace disposable filters or clean reusable filters monthly, or more often if you have pets or live in a dusty area.
Inspect the Outdoor Unit
Make sure the outdoor unit is free from debris such as leaves, branches, and grass clippings. Clear any obstructions within two feet of the unit to ensure proper airflow. A blocked outdoor unit can lead to overheating and reduced cooling capacity.
Thermostat Settings
Ensure your thermostat is set to "cool" and the temperature is lower than the current room temperature. Check the batteries in your thermostat and replace them if necessary. Sometimes, a simple thermostat adjustment can resolve cooling issues.

Check for Obvious Issues
Look for visible signs of damage or leaks around your AC unit and ductwork. Examine the insulation on refrigerant lines and repair or replace any damaged sections. Addressing these issues early can prevent further damage and improve efficiency.
