It’s frustrating when your air conditioner runs, but your home still feels warm and uncomfortable. There are various reasons why your AC might fail to cool properly, and knowing where to start can help you troubleshoot the issue more effectively. With our expertise at [company_name] in Memphis, TN, we’re here to break down the common causes and how you can get your system running smoothly again, giving you the confidence that your AC is in good hands.
Low Refrigerant Levels and How They Affect Cooling
A low refrigerant level is one of the most common reasons your air conditioner might be running but not cooling. The refrigerant in your AC absorbs and releases heat; without it at the proper level, the system can’t effectively cool the air in your home. If the refrigerant is low, it typically indicates a leak somewhere in the system. This issue requires professional attention because the refrigerant needs to be handled carefully, and locating the leak can be tricky without the right equipment. Attempting to handle refrigerant without the proper training and equipment can be dangerous, so it’s best to leave this task to the professionals.
When the refrigerant is low, your AC system can still run, but it won’t have enough refrigerant to absorb the heat inside your home correctly. As a result, the air conditioning process becomes inefficient, and you’ll notice the temperature in your home staying uncomfortably high. Suppose you suspect a refrigerant leak or low refrigerant. In that case, it’s important to have the system inspected as soon as possible to prevent further damage to the compressor, which can be an expensive repair.
Dirty Air Filters and Their Impact on Cooling
A dirty or clogged air filter is another simple yet often overlooked cause of poor cooling performance. Air filters trap dust, dirt, and other particles in the air, preventing them from entering the cooling coils and damaging the system. However, if the filter is dirty or clogged, the airflow to the system is restricted. This makes it harder for the air conditioner to circulate cool air and can lead to the system freezing up or not cooling as effectively.
The good news is that this is one of the easiest issues to fix. You can replace or clean the filter yourself to improve airflow and cooling, empowering you to take control of your AC’s performance. Make it a habit to check your air filter every month, especially during the hotter months when your AC runs more often. Depending on the type of filter, it can be replaced every one to three months. Keeping the filter clean ensures your system operates more efficiently, saves energy, and cools better.
Frozen Evaporator Coils and How They Affect Cooling
Frozen evaporator coils are a common problem that can stop your air conditioner from cooling. The coil takes in heat from the air, but when it freezes, the AC can’t do its job. When your coils freeze, they block the airflow and prevent your AC from cooling the air.
A few factors, including a clogged air filter, low refrigerant, or poor airflow, often cause a frozen evaporator coil. If your system is low on refrigerant or the filter is clogged, it is harder to absorb heat. When this happens, the coils can freeze. If you notice your AC running but not cooling, and the coils are frozen, you should first turn off the system and let it thaw. You can try replacing the air filter and checking for any leaks or issues with refrigerant, but if the problem persists, it’s time to call a professional.
Thermostat Issues and Incorrect Settings
Sometimes, the problem isn’t with the AC system but with the thermostat. If your thermostat isn’t working properly or is set incorrectly, it might be causing your air conditioner to run inefficiently. If the thermostat is set to an unrealistic temperature or is malfunctioning, it might tell the system to cool more than needed, leading to poor performance.
First, check your thermostat settings to make sure they’re correct. If it’s not working right, it may need to be fixed or replaced. Also, make sure your thermostat is placed in a good location. For example, placing it near heat sources like a lamp or direct sunlight could cause it to read the temperature incorrectly, which can affect the cooling performance of your air conditioner. Ensure the thermostat works correctly and is properly set to maintain a comfortable temperature.
