Common Causes of AC Issues

Air conditioning systems require regular service and maintenance to work efficiently and stay in good condition. Unfortunately, most people ignore their air conditioning systems until they stop working.


If you want to ensure optimal performance, you should regularly clean and service your air conditioner. Routine maintenance can save you money and increase the lifespan of your system. Even with the best maintenance plan, air conditioning units experience issues from time to time. Let’s look at some of the common causes of AC issues.


6 Some Common Causes of AC Issues


Here are the most common causes of air conditioning system problems:


1.   Refrigerant Leaks


The refrigerant in your air conditioner, commonly known as Freon, has the primary task of chilling the air. If your air conditioner runs short on refrigerant, it was either installed incorrectly or leaks. Adding more refrigerant will only temporarily clear up the problem if there is a leak. Since the refrigerant used in your AC is hazardous to the environment, you should contact a qualified expert if you suspect a refrigerant leak.


2. Issues with the Circuit Breaker, Fuse, or Thermostat


You should also check your circuit breaker and fuse if your air conditioner fails. Wait for 15 minutes to let your system cool down before replacing a fuse or resetting the breaker. If you still have older, dial-type thermostats, you should replace them immediately. You should also check the battery in your thermostat as dead batteries can easily be the cause of your system stopping. By replacing or recalibrating your thermostats, you may solve the problem quickly and easily. Contact a professional AC repair service to handle these problems.


3. Frozen Evaporator Coils


Your air conditioner’s evaporator coil is loaded with refrigerant and works to absorb heat from the air. Although it may appear illogical, the coils require warm air to function effectively. In some cases, a coating of ice can form outside the unit when the airflow is disrupted. When the evaporator coil becomes too cold or freezes, you will get hot air or no air at all.


4. Faulty Fans


Your AC’s fan blows air over the evaporator coil of your indoor unit to cool it, and another fan blows air over the condenser of your outdoor unit to release the absorbed heat outside your home. If either fan isn’t working correctly, you’ll notice an issue with your air conditioning unit. Ignoring faulty fans can lead to compressor failure, which will stop your entire system.


5. Blocked Drains


Your air conditioning system gets rid of all of the dampness it takes from the air using drains. Water can move back into your system when drains get blocked by dirt or debris and ruin your AC. Water leaks can also cause interior damage to your walls, furniture, and ceilings. If your air conditioning unit isn’t functioning correctly, contact a local AC company to check for blocked drains.


6. Filthy Condenser Coils


The heat extracted from your air is pushed outside by the unit’s condenser coils. When a coating of dirt and dust covers the condenser coil, it will no longer function efficiently. When this occurs, your unit works harder to cool your home, increasing the wear and tear on your system and possibly leading to total system failure.
