Air conditioning systems are essential for maintaining a comfortable living environment, especially during the hot summer months. However, like any other appliance, AC systems can develop problems over time due to various factors, ranging from general wear and tear to lack of maintenance.

Learn the top 5 common AC problems homeowners may encounter and provide their respective solutions. By learning to recognize these issues and taking timely action, you can help ensure the efficient operation and longevity of your air conditioning system, keeping your home comfortable and cool all season long.

1. Refrigerant Leaks: A Common AC Issue with a Straightforward Solution


Refrigerant is essential for your air conditioner to function, as it absorbs heat from your home’s air and transfers it outside, cooling the indoor temperature. One of the most common AC problems is low refrigerant levels due to leaks in the coils or connections. If you notice that your AC is not cooling your home effectively, or if you see ice forming on the evaporator coils, you may have a refrigerant leak.

To address this issue, we recommend calling our professional technicians to inspect your system, locate the leak, and repair it. It is crucial not to attempt to refill refrigerant on your own, as improper handling can be hazardous and damage your AC unit. Our technicians will then recharge the refrigerant, ensuring that your system operates efficiently and keeps your home comfortable.

2. Dirty or Clogged Filters: An Easily Preventable Problem


Air filters play a vital role in ensuring the efficient operation of your air conditioner. They remove dirt, dust, and other particles from the air entering your system, preventing damage to internal components. However, over time, these filters can become dirty or clogged, restricting airflow and causing your AC to work harder to cool your home, leading to increased energy consumption and reduced performance.

To solve this issue, regularly check your air filters and replace them as needed. Most filters should be changed every 30-90 days, depending on the filter type and your household’s air quality. By keeping filters clean, you can optimize your AC’s performance and maintain a healthy indoor air environment.

3. Thermostat Issues: Regulating Temperature Control


The thermostat is your air conditioning system’s control center, ensuring that your home’s temperature remains within your desired comfort range. However, thermostat issues, such as incorrect settings, inaccurate readings, or electrical problems, can negatively impact your AC’s performance and make your home uncomfortable.

To resolve thermostat issues, first, check that your thermostat is set to the appropriate temperature and mode. If the problem persists, it may be due to incorrect calibration or electrical malfunctions. In such cases, we recommend enlisting our experienced technicians to assess the issue and provide appropriate solutions, such as recalibrating the thermostat or repairing any electrical issues.

4. Frozen Evaporator Coils: A Frosty Problem


Evaporator coils are vital for absorbing heat from your home’s air and transferring it outside. When working correctly, these coils maintain just the right temperature to prevent the condensation on them from freezing. However, if airflow is restricted due to dirty filters, low refrigerant levels, or blocked vents, the coils can become too cold and freeze, resulting in reduced cooling performance and potential damage to your AC system.

To fix frozen evaporator coils, turn off your air conditioner and allow the ice to melt. Check your air filters for clogs and ensure all vents are unobstructed. If these steps do not resolve the issue, contact our technicians to diagnose the underlying problem, such as refrigerant leaks, and provide the necessary repairs to restore your AC’s performance.

5. AC Fan Malfunctions: Maintaining Proper Air Circulation


Two fans are essential for your air conditioner’s operation: the evaporator fan, which blows cooled air into your home, and the condenser fan, which expels heat from the condenser unit outside. If either of these fans experiences a malfunction, such as a motor failure, worn belts, or damaged blades, your AC may struggle to cool your home effectively or even overheat.

If you suspect fan-related issues, turn off your air conditioner and inspect the fans for visible damage or debris that may obstruct their movement. If you cannot identify the problem, or if motor or belt replacements are necessary, we recommend calling our professional technicians to perform repairs and ensure proper fan operation.
