Why Is My Air Conditioner Running But Not Cooling The House?

June 11, 2024

It’s the height of summer, and the last thing you want is an air conditioner that acts more like a fan, running without cooling your house. If you’ve been asking yourself, “Why is my air conditioner running but not cooling the house?” you’re not alone. This common issue can be frustrating, but with the right knowledge, you can pinpoint the problem and find a solution. Let’s dive into the reasons behind this cooling conundrum and how you can get your home back to being the oasis of coolness it should be.

Get the Cool Back In Your Home

Common Causes and Fixes

  • Dirty Air Filter: A clogged air filter restricts airflow, significantly reducing cooling efficiency. Regularly check and replace your air filter to ensure smooth operation.
  • Thermostat Issues: Sometimes the problem is as simple as incorrect thermostat settings. Make sure it’s set to “cool” and not just “fan” mode. Also, check if the thermostat is working properly.
  • Low Refrigerant: Refrigerant is essential for cooling your home. Low levels due to leaks can cause your unit to underperform. If you suspect a refrigerant issue, it’s time to call in a professional.
  • Dirty Condenser Coils: The condenser coils, located outside your home, can become dirty and impede heat transfer. Cleaning these coils can significantly improve your AC’s effectiveness.
  • Frozen Evaporator Coils: If your evaporator coils freeze, your AC will run but not cool. This can be due to low refrigerant or airflow problems. Turning off your AC and letting the coils thaw is a temporary fix, but identifying the root cause is essential.

Preventative Maintenance

The key to avoiding these issues is regular maintenance. Scheduling annual check-ups for your air conditioner can prevent many common problems that lead to inefficiency and breakdowns. A professional can check refrigerant levels, inspect electrical connections, and ensure all components are in good working order.

When to Call a Professional

While some fixes, like replacing an air filter, are simple, others require the expertise of a professional. If your air conditioner is not cooling after basic troubleshooting, it’s time to call in the experts. This is especially true for refrigerant issues, electrical problems, and anything involving the internal components of your AC unit.
