There’s nothing worse than a Texas summer with an air conditioner that isn’t cooling right. If your AC is running but not doing its job, here are the most common reasons — and what you can do about them.
A dirty filter restricts airflow, forcing your system to work harder. Replace or clean filters every 1–2 months to maintain performance.
Refrigerant is what cools the air in your system. If levels are low, it could indicate a leak — a problem only a licensed technician should fix.
Incorrect thermostat settings or a faulty sensor can cause uneven cooling. Check your settings before assuming a system issue.
Leaks or blockages in your ducts can cause cool air to escape, making your AC less effective. Duct inspections help ensure efficient airflow.
When outdoor coils are covered in dirt or debris, heat can’t escape properly — reducing cooling power. Regular cleaning keeps your system efficient.
If your AC is too small for your space or over 10–15 years old, it may not cool effectively. In that case, upgrading to a modern, energy-efficient system is best.
