Why Your Air Conditioning System is Only Blowing Warm Air

Posted on: 14 September 2023

It could be confusing when your system is not cooling the air as it should. If you find yourself in this predicament, you are not alone. Here are some of the possible reasons why your air conditioning system is blowing warm air and what you can do to fix it.

Dirty Air Filter: If your AC is blowing warm air, a clogged air filter is often the culprit. It prevents the system from properly circulating the air, causing it to overheat and not function correctly. The air filter should ideally be replaced every few months, depending on usage. It's good practice to check your filter regularly to make sure it's clean and functioning correctly.

Clogged Condenser: The condenser is a vital part of your AC system located outside your house. It's responsible for dissipating heat from the refrigerant and turning it back into a liquid, repeating the process. It's no secret that with time, dirt, dust, and debris will accumulate on the condenser and reduce its efficiency in cooling the refrigerant. If your condenser is clogged or dirty, it could cause your air conditioning system to blow warm air. Make sure to keep your condenser clean to keep your system functioning correctly.

Low Refrigerant Levels: Refrigerant is the essential component of AC systems, responsible for cooling the air by absorbing heat. It's necessary to have the right amount of refrigerant in your system, or else it won't cool correctly. If your system is low on refrigerant, it's most likely due to a leak, which could happen because of corrosion or wear and tear. A professional technician can fix the leak, identify how much refrigerant is needed, and recharge your system.

Faulty Compressor: The compressor of your AC system is responsible for compressing refrigerant gas and circulating it through the system to cool your home. If the compressor isn't working correctly, it could lead to your system blowing warm air. It's mostly caused by wear and tear, age, or incorrect installation. An experienced HVAC technician has the expertise to identify and resolve the issue.

Electrical Problems: Electrical issues could be another cause of your system blowing warm air. It could range from a blown fuse to a broken wire, causing the system to malfunction. Check your breakers and fuses to make sure they are functioning correctly. Nevertheless, electrical problems can pose a safety hazard, so it is advisable to contact a skilled technician to assess and resolve the issue.

There are many reasons why your AC system might be blowing warm air. Regular maintenance, such as cleaning or changing your air filter, can prevent many potential problems. If your system is still not operating properly, you should consider contacting a professional technician to assess and resolve the issue. Keep in mind that maintaining your AC system can help you save money in the long term by preventing expensive repairs and extending the lifespan of your unit.
