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

May 30, 2024 | Blog

As the summer heat ramps up in Birmingham, AL, the last thing you want is for your air conditioner to run but not blow cold air. This common issue can be particularly frustrating during the hot and humid Alabama summers. At Brown Cooling, Heating, Plumbing & Electrical, we understand the importance of a well-functioning air conditioning system. Let’s explore some common reasons why your A/C might be running but not cooling, and how you can address these issues.

High Humidity Levels in Birmingham

Birmingham is known for its high humidity levels, especially during the summer months. High humidity can significantly impact the efficiency of your air conditioning system. When humidity is high, your A/C has to work harder to remove moisture from the air, which can make it seem like your system is not cooling effectively.

Expert Tip: Installing a whole-house dehumidifier can help reduce indoor humidity levels, allowing your air conditioner to cool more efficiently.

Dirty Air Filters

One of the most common reasons for an A/C running but not blowing cold air is a dirty air filter. In Birmingham, where allergens and air quality can fluctuate, it’s essential to regularly check and replace your air filters.

Expert Tip: Change your air filters every 1-3 months, or more frequently if you have pets or allergies.

Refrigerant Leaks

Refrigerant is essential for your A/C to cool the air. Low refrigerant levels, often due to leaks, can prevent your system from blowing cold air. This issue requires immediate attention from a professional.

Expert Tip: Contact Brown Cooling, Heating, Plumbing & Electrical at (205) 418-8486 to schedule a refrigerant check and refill.

Condenser Unit Issues

The outdoor condenser unit plays a crucial role in the cooling process. If the condenser is dirty or blocked, it can hinder your A/C’s ability to cool your home effectively.

Expert Tip: Ensure the area around your condenser unit is clear of debris and plants. Schedule regular maintenance to keep the condenser clean and functioning properly.

Thermostat Problems

A malfunctioning thermostat can also cause your A/C to run without cooling. Make sure your thermostat is set to the correct temperature and is functioning properly.

Expert Tip: If your thermostat is outdated or not working correctly, consider upgrading to a programmable thermostat for better temperature control.

Frozen Evaporator Coils

Frozen evaporator coils can prevent your A/C from cooling the air. This can happen due to restricted airflow, typically caused by dirty filters or blocked vents.

Expert Tip: Turn off your A/C and let the coils thaw. Check your air filters and vents to ensure proper airflow.

Electrical Issues

Birmingham’s frequent thunderstorms can lead to power surges that might damage your A/C system’s electrical components, causing it to malfunction.

Expert Tip: Installing surge protectors can help prevent damage to your HVAC system. If you suspect an electrical issue, contact us for a professional inspection.

Regular Maintenance

Routine maintenance is key to ensuring your air conditioner operates efficiently. At Brown Cooling, Heating, Plumbing & Electrical, we offer comprehensive HVAC maintenance services to keep your system in top shape.

Expert Tip: Schedule regular maintenance appointments with our team to catch potential issues before they become major problems.

The Service Was Excellent

We called late one evening after our AC went out. They were very responsive and technician David Monk was at our home at 8:00am the next day as promised. He diagnosed the issue, got the part needed, installed and tested it all by 10:00am. The service was excellent and David was so nice and personable. I would highly recommend this company.
