What is the Most Common Early Failure on a Central Air Conditioning System?

Air conditioning failure can be terrifying, especially if your area experiences extra hot summers. Whether it’s your household cooling or commercial AC system, common AC failures occur early on during its use. Knowing these problems before they happen helps prevent them and makes you enjoy your HVAC system when you need it. You will also save money if you identify a potential breakdown before it happens.

1. Fuse Failure

During the summer, the electrical system is overwhelmed by loading different home appliances. The high-pressure limit of your air conditioner’s circuit breaker can trip. If the circuit breaker does not revert to its original operations through flipping, do not adjust it by yourself; call a professional AC repair technician.

2. Drainage Issues

The ACs drain pipeline can get clogged with dirt, algae, and dust. Mildew, fungus, and mold can develop if water fails to drain appropriately. Furthermore, foul odors and gases can filter into the home. Have a professional AC technician inspect, clean, and maintain your HVAC system regularly. Also, air conditioners mounted unevenly may also not drain properly.

3. Sensor Failure

The air conditioner has a thermostat near the evaporator coil. The thermostat’s function is to measure air temperature inside the evaporator coil and regulate the cooling depending on room conditions. If the sensor moves out of position, it makes the air conditioner turn on and off randomly or cycle constantly. Ensure that the sensor is near the evaporator coil but not touching it. You can bend the wire holding the sensor in position to adjust it.

4. Refrigerant Leak

Your AC system can experience different types of leaks. Among them is the failure to sense refrigerant gas, making it take longer to lose its cooling capacity. AC system refrigerant harms the environment, and a leak should be recharged and repaired by a licensed AC technician.

5. Frozen Evaporator Coil

The coil in the evaporator freezes when there is insufficient air in the air conditioner to make it operate as expected. A frozen evaporator coil can freeze up your AC, making it stop working. Blocked ducts and vents, a faulty fan, or dirty filters can limit airflow in the AC system. The AC needs a clean air filter to maximize indoor air quality and airflow.

6. AC Making Noises

Your AC can produce different noises depending on the problem. The AC may make other noises because of various reasons, including:

• A hissing sound means you have a refrigerant leak
• Clicking sounds when turning on and turning off the AC indicate a relay issue
• Banging, rattling, or thumping noises show a problem with the motor assembly or blower
• A screeching noise is heard when there is a problem with the fan motor or compressor
• A buzzing sound means that your AC electrical components are faulty
