Air conditioning is a necessity in warmer parts of the world, whether year-round or seasonally. But if your air conditioner breaks down, it could become downright unbearable. Repairs can be expensive so you want to ensure that your air conditioner is in the best shape to last you a long while. 

All air conditioners need some TLC to keep them in top shape and increase longevity. Keep yours running by knowing the common air conditioner problems. And learn how to keep your AC in tip-top shape all year long!

1. Bad Filters

One of the most common air conditioner problems is having a clogged or dirty filter. You should be following your AC’s manufacturer’s suggestions to understand how often your air filter needs to be changed. Some central air conditioning requires a monthly filter change while others are reusable and must be cleaned once they’re dirty. 

A great way to determine if your filter needs cleaning is by checking if light can pass through it. If not, then you know it’s time to have it cleaned. A dirty filter not only reduces airflow but it can also cause an AC unit to freeze. 

2. The Thermostat

Another problem with central air conditioning could be the temperature you have it set on. A simple fix to this would be making sure that your thermostat is turned on an appropriate temperature, is clean on the inside, is level, and is not being affected by any sunlight. If you notice any problems persisting, there could be other issues

You should also make sure that your air conditioner is only being run when you need it. Avoid running the unit overnight as that can negatively affect its functions. Once you find a comfortable temperature, maintain the unit to run at that level for the duration of usage. 

3. Burned Out Capacitators

Air conditioners need capacitors for the motors can power the compressor and work the fans on the unit. The start capacitor jolts and activates the motor and the run capacitor creates a series of jolts for the motor to keep working. Therefore, if these capacitors burn out, the air conditioner won’t run efficiently. 

4. Condenser Coils

You can find the condenser coils on the outside of the compressor so it’s easy for them to get dirty because of the elements. You can typically clean them using a water hose once every year. However, if they become too dirty, you’ll need an HVAC technician to clean them with a professional chemical cleaner.

5. Dysfunctional Compressor 

The air conditioner’s compressor is what adds energy to the refrigerant. This then moves through the coils to distribute heat and exchange it for cooler air. Your home won’t be able to cool down if your AC unit’s compressor is dysfunctional. 

If there isn’t enough refrigerant, the compressor can run hot and ultimately seize. If there’s too much refrigerant, it’ll return to the compressor and ultimately fail. There must be a balance that only a healthy, functioning compressor can produce.
