Why Your AC is Running But Not Cooling

In the midst of a sweltering summer, there’s nothing more frustrating than an air conditioner that hums along but doesn’t cool. If your AC is running but not blowing cold air and lowering the temperature in your home, it’s not just a nuisance; it’s a cry for help. Let’s explore the common reasons behind this issue and how to get your cool air back. 🌡️🛠️

A dirty air filter, a faulty thermostat, improper insulation, wrong sized ductwork and duct leaks, improper installation, and an overworked or aging system are all possible causes of air conditioners running but not cooling. But today, we’re going to talk about the most likely culprit:

Insufficient Refrigerant and Refrigerant Leaks: The Cooling Culprits

One of the most common yet overlooked reasons an air conditioning system fails to cool properly is due to insufficient refrigerant or refrigerant leaks. Understanding how these issues affect your AC’s performance is crucial for maintaining a comfortable indoor environment, especially during the warmer months.

The Role of Refrigerant in Your AC System

Refrigerant is the lifeblood of any air conditioning system. It flows through the coils of your AC, absorbing heat from the indoor air and releasing it outside, thus cooling your home. This process is continuous, ensuring that your living space remains at the desired temperature.

How Insufficient Refrigerant Affects Cooling

When the refrigerant level in your AC system is lower than required, the cooling cycle is disrupted. The system struggles to absorb and expel enough heat, leading to inadequate cooling. Symptoms of low refrigerant include:

• The air conditioner runs longer than usual but fails to cool the room effectively.
• Ice formation on the refrigerant lines or the outdoor unit.
• Higher than normal energy bills due to the AC overworking to try to cool your home.

Refrigerant Leaks: A Double Trouble

Refrigerant leaks not only cause low refrigerant levels but also pose environmental and health risks. A leak can occur due to various reasons, including corrosion, physical damage to the coils, or loose connections. Signs of a refrigerant leak include:

• Hissing or bubbling noises from the AC unit, indicating escaping gas.
• Pools of liquid near the AC unit.
• An unexplained increase in humidity levels inside your home.

Addressing Refrigerant Issues

Dealing with insufficient refrigerant and leaks is not a DIY job. It requires the expertise of a certified HVAC technician who can:

• Detect and Repair Leaks: Using specialized equipment, a technician can locate leaks within the system, repair them, and test to ensure the repairs hold.
• Recharge Refrigerant: After repairing any leaks, the technician will recharge the system with the correct type and amount of refrigerant according to the manufacturer’s specifications.
• System Check and Maintenance: To prevent future issues, a comprehensive system check is performed to ensure all components are functioning correctly, and routine maintenance is recommended.

The Importance of Professional Intervention

Handling refrigerants requires specialized knowledge and tools, as well as adherence to environmental regulations regarding the handling and disposal of refrigerants. Professional HVAC technicians are trained and certified to manage these tasks safely and efficiently, ensuring your system’s longevity and your home’s comfort.

In summary, insufficient refrigerant and refrigerant leaks significantly impact your AC’s ability to cool your home effectively. Recognizing the signs of these issues and seeking professional assistance promptly can save you from discomfort, high energy bills, and potential health risks, ensuring your system operates efficiently and reliably.

When your AC runs but doesn’t cool, it’s a clear sign that something’s amiss. From dirty filters to insufficient refrigerant, and from faulty thermostats to improper installation, the reasons vary. Identifying and addressing the root cause is key to restoring your home’s comfort. Regular maintenance and timely repairs can keep your system running efficiently, ensuring you stay cool all summer long.
