Understanding the Problem: Why Is Your AC Not Cooling?

Is your air conditioner failing to keep your home cool despite running constantly? It can be frustrating to deal with a malfunctioning AC unit. At Liam Services, we understand the importance of a comfortable indoor environment, which is why we’ve compiled this troubleshooting guide to help you identify and resolve common issues affecting your AC’s cooling performance.

Check the Thermostat Settings

Start by checking your thermostat settings to ensure they’re properly configured for cooling mode. Verify that the temperature setting is lower than the current room temperature and that the fan is set to “auto” rather than “on.”

Inspect the Air Filter

A dirty or clogged air filter can obstruct airflow and reduce your AC’s cooling efficiency. Check the air filter and replace it if it’s dirty or clogged. Regularly changing your air filter can improve indoor air quality and prevent cooling problems.

Examine the Outdoor Unit

Inspect the outdoor condenser unit for any visible signs of damage, such as debris buildup, bent fins, or vegetation encroachment. Ensure that the unit is free from obstructions and has proper clearance for airflow. Additionally, clean the condenser coils to remove dirt and debris that can hinder heat transfer.

Assess Refrigerant Levels

Inadequate refrigerant levels can hamper your AC’s ability to cool effectively. If you notice ice buildup on the refrigerant lines or evaporator coil, it may indicate a refrigerant leak. Contact our HVAC experts at Liam Services to diagnose and repair refrigerant leaks and recharge your system with the correct refrigerant type and quantity.

Check for Air Duct Leaks

Leaky air ducts can result in cooled air escaping before reaching your living spaces, leading to reduced cooling performance and higher energy bills. Conduct a visual inspection of your ductwork for any signs of leaks, such as visible gaps or disconnected sections. Our team can seal and insulate ductwork to improve airflow and energy efficiency.

Schedule Professional Maintenance

Regular maintenance is essential for keeping your AC in peak condition and preventing cooling problems. Schedule routine maintenance visits with Liam Services to have your AC inspected, cleaned, and tuned up by our experienced HVAC technicians. Our comprehensive maintenance services can prolong the lifespan of your AC and ensure optimal performance throughout the summer months.

Should I turn off my AC if it’s not cooling?

It’s generally a good idea to turn off your AC if it’s not cooling properly. Continuing to run the unit could potentially worsen the problem and lead to further damage. Once the AC is turned off, you can try basic troubleshooting steps or contact a professional for AC repair near you.

How can I fix my AC if it’s not blowing cold air?

Several factors could cause your AC to stop blowing cold air, including dirty air filters, refrigerant leaks, or issues with the compressor. Start by checking and replacing dirty filters, ensuring vents are open, and checking for any visible signs of leaks. If the issue persists, contact an HVAC technician for a thorough inspection and repair.

What’s the process for resetting an air conditioner?

Resetting an air conditioner typically involves turning off the unit completely, including the thermostat, for a few minutes and then turning it back on. This allows the system to reset and often resolves minor issues. If the problem persists after resetting, it may indicate a more significant issue that requires professional attention.

How can I determine if my AC compressor is malfunctioning?

Signs of a faulty AC compressor include loud or unusual noises, warm air blowing from vents, and visible leaks around the unit. Additionally, if your AC cycles on and off frequently without adequately cooling your home, it could indicate compressor issues. Contacting an AC repair technician for a comprehensive inspection is advisable in such cases.

How do I know if my AC compressor is low on Freon?

Symptoms of low refrigerant (Freon) levels in your AC system include reduced cooling efficiency, ice buildup on the refrigerant lines or evaporator coil, and hissing or bubbling noises from the unit. If you suspect low Freon levels, it’s essential to have a professional HVAC technician diagnose and address the issue promptly to prevent further damage to your system.
