Why is My AC Running but Not Cooling?
As the sweltering heat of Dallas, TX, sets in, having an air conditioner that runs but doesn’t cool can be a significant discomfort. At Fast Response Heating & Cooling, we understand how crucial it is to have a fully functioning air conditioning system. Here are some common reasons why your AC might be running but not cooling and what you can do to fix the problem.
Dirty Air Filter
One of the most frequent culprits behind an AC that runs without cooling effectively is a dirty air filter. When the filter is clogged with dust and debris, it restricts airflow, causing your system to work harder without delivering the desired cooling effect. To fix this, check your air filter every month and replace it as needed, especially during peak usage periods.
Refrigerant Leak
Refrigerant is essential for your AC to cool the air. If there’s a leak, the refrigerant level drops, reducing the system’s ability to cool your home. Signs of a refrigerant leak include ice on the refrigerant lines and hissing sounds. It’s important to contact a professional HVAC technician from Fast Response Heating & Cooling to diagnose and fix refrigerant issues, as handling refrigerant requires specialized training.
Blocked Condenser Unit
The condenser unit, located outside your home, can become blocked by leaves, dirt, and other debris. This blockage can hinder the heat exchange process, making it difficult for your AC to cool the air effectively. Regularly check the condenser unit and clear away any debris to ensure proper airflow. Additionally, schedule routine maintenance with our team to keep your condenser in optimal condition.
Faulty Thermostat
Sometimes, the issue might be as simple as a malfunctioning thermostat. If your thermostat isn’t working correctly, it may not be signaling your AC to cool the air as needed. Ensure your thermostat is set to the correct temperature and mode. If the problem persists, it might be time to replace the thermostat or check for wiring issues.
Dirty Evaporator Coils
Over time, evaporator coils can collect dirt and dust, reducing their efficiency. When the coils are dirty, they cannot absorb heat effectively, which impacts the cooling process. Cleaning the coils requires a professional touch, so schedule a maintenance visit from Fast Response Heating & Cooling to have your evaporator coils inspected and cleaned.
Leaky Ductwork
Leaky ductwork can lead to cooled air escaping before it reaches your living spaces, resulting in an AC system that runs continuously without effectively cooling your home. Inspect your ducts for any visible leaks or damage and have them sealed by a professional to improve cooling efficiency.
Aging AC Unit
If your air conditioner is old, it might not cool as efficiently as it used to. Most AC units have a lifespan of around 10-12 years. If your system is nearing or has exceeded this age, it might be time to consider upgrading to a newer, more energy-efficient model. Fast Response Heating & Cooling offers a range of modern AC units that can provide better cooling and energy savings.
