As a homeowner, dealing with AC failure can be a frustrating and costly experience. In this blog post, we will discuss 5 common causes of AC failure and provide tips on how to prevent them and keep your home comfortable all year round. By being proactive and addressing potential problems before they become major issues, you can save time, money, and frustration in the long run.

1. Dirty or Clogged Filters

One of the most common causes of AC failure is dirty or clogged filters. Over time, dust, dirt, pollen, and other debris can accumulate on your air filters, restricting airflow and causing your AC system to work harder than necessary. This can lead to reduced efficiency, increased energy costs, and even system failure.

To prevent this issue:

Check your air filters regularly and replace them as needed, typically every 1-3 months depending on usage and environmental factors.
Consider investing in high-quality, reusable filters that can be cleaned and reused.
Schedule regular maintenance with a professional HVAC technician to ensure your system is running efficiently and to address any potential issues before they become major problems.

2. Refrigerant Leaks

Refrigerant is the substance that your AC system uses to cool the air in your home. If your system develops a refrigerant leak, it can cause a variety of issues, including reduced cooling capacity, higher energy bills, and even system failure.

To prevent refrigerant leaks:

Have your AC system inspected regularly by a professional technician to check for signs of leaks and address any issues before they become major problems.
Ensure proper installation and maintenance of your AC system to prevent leaks from occurring in the first place.
Be aware of the phase-out of R-22 refrigerant and consider upgrading to a more environmentally friendly and efficient AC system if necessary.

3. Electrical Issues

Electrical issues are another common cause of AC failure. These can include problems with wiring, circuit breakers, or electrical components within your AC system.

To prevent electrical issues:

Have your AC system inspected regularly by a professional technician to check for signs of electrical problems and address any issues before they become major problems.
Consider investing in a high-quality, energy-efficient AC system to reduce the risk of electrical problems and save on energy costs.

4. Frozen Evaporator Coils

Frozen evaporator coils can cause your AC system to stop working and may even lead to system failure. This issue is often caused by restricted airflow due to dirty filters or other issues.

To prevent frozen evaporator coils:

Check your air filters regularly and replace them as needed to ensure proper airflow.
Keep your AC system clean and free of debris to prevent airflow restrictions.
Schedule regular maintenance with a professional HVAC technician to address any potential issues before they become major problems.

5. Improper Installation or Sizing

Improper installation or sizing of your AC system can cause a variety of issues, including reduced efficiency, increased energy costs, and even system failure.

To prevent these problems:

Work with a reputable HVAC contractor to ensure proper installation and sizing of your AC system.
Consider upgrading to a more energy-efficient AC system if your current system is not properly sized for your home.
