Why Is My Air Conditioner Running but Not Blowing Cold Air?

June 6, 2024 | Blog

Residents of Broussard, Jeanerette, Lafayette, and New Iberia know how essential a well-functioning air conditioner is to combat the Louisiana heat. If your A/C is running but not blowing cold air, it’s crucial to identify the issue and address it promptly. Tim’s Southern Air Heating, Cooling, & Plumbing is here to help you understand the common reasons for this problem and how to fix them.

Why is my air conditioner running but not blowing cold air


1. Clogged Air Filters

Dirty or clogged air filters can restrict airflow, causing your air conditioning to run inefficiently. This can result in a lack of cold air. Regularly check and replace your filters to maintain optimal performance.

Expert Tip: Check your air filters monthly and replace them every 1-3 months, depending on usage and manufacturer recommendations.

2. Refrigerant Leaks

Low refrigerant levels can prevent your A/C from cooling your home properly. A refrigerant leak is often the culprit behind insufficient cooling. Contact Tim’s Southern Air Heating, Cooling, & Plumbing at (337) 240-6927 for a professional diagnosis and repair.

Expert Tip: Schedule annual refrigerant level checks to ensure your system is fully charged and operating efficiently.

3. Thermostat Issues

A malfunctioning thermostat can cause your A/C to run without cooling effectively. Ensure your thermostat is set correctly and functioning properly.

Expert Tip: Upgrade to a programmable or smart thermostat for more precise temperature control and energy savings.

4. Dirty Coils

Evaporator and condenser coils can accumulate dirt over time, reducing their ability to cool air efficiently. Regular cleaning is essential to keep your A/C running smoothly.

Expert Tip: Clean the coils annually or as needed to maintain efficient cooling performance.

5. Electrical Problems

Electrical issues, such as faulty wiring or tripped breakers, can prevent your A/C from cooling your home. If you suspect an electrical problem, it’s best to call a professional.

Expert Tip: Have a licensed technician inspect your A/C’s electrical components during regular maintenance visits.

Preventive Maintenance

The best way to avoid A/C problems is through regular preventive maintenance. Schedule a tune-up with Tim’s Southern Air Heating, Cooling, & Plumbing to ensure your system is ready for the Louisiana heat.
