5 Common Causes of AC Breakdowns and How to Avoid Them

As summer approaches and temperatures rise, air conditioning (AC) becomes a necessity for many households. However, AC units can sometimes break down, leaving you with an uncomfortable living environment. To help you avoid a costly ac repair in Palm Desert, here’s a compiled list of the most common causes of AC breakdowns and tips on preventing them.

  1. Dirty or Clogged Filters

A dirty or clogged filter is one of the leading causes of AC breakdowns. When the filter becomes clogged with dust and debris, it restricts airflow, forcing your system to work harder to maintain the desired temperature. This can decrease efficiency and even cause the unit to overheat and break down.

How to Avoid: To prevent this issue, replace or clean your AC filter regularly, typically every one to three months. Regular maintenance and inspection of your air conditioning system can also help you identify issues before they lead to breakdowns.

  1. Refrigerant Leaks

Refrigerant is the lifeblood of your AC unit, responsible for removing heat from the air and cooling your home. A leak in your AC unit’s refrigerant line can cause the system to function poorly or not at all, leading to a breakdown.

How to Avoid: If you suspect a refrigerant leak, it’s essential to call a professional HVAC technician to fix the problem, as handling refrigerant requires specific expertise and safety precautions. Regular maintenance can also help detect leaks early on and address them before they lead to a breakdown.

  1. Frozen Evaporator Coil

A frozen evaporator coil can be another culprit behind an AC breakdown. When the evaporator coil freezes, it cannot effectively absorb heat from the air, causing the system to malfunction or stop working altogether.

How to Avoid: To prevent a frozen evaporator coil, ensure that your AC filter is clean and free of debris, as this can restrict airflow and cause the coil to freeze. Additionally, monitor your system’s refrigerant levels and consult a professional if you notice a significant drop or suspect a leak.

  1. Electrical Issues

Electrical problems, such as a faulty thermostat, a malfunctioning capacitor, or a worn-out contactor, can cause your AC unit to break down. These issues can lead to inconsistent performance, frequent cycling, or the system not turning on.

How to Avoid: To prevent electrical issues, it’s crucial to schedule regular maintenance with a professional HVAC technician. They can identify and address electrical problems before they escalate and cause a breakdown. Consider investing in a surge protector to protect your unit from power surges and voltage fluctuations.

  1. Lack of Maintenance

Neglecting regular maintenance is one of the primary causes of AC breakdowns. Routine maintenance helps identify potential issues early on and ensures your system runs efficiently.

How to Avoid: Schedule regular maintenance with a professional HVAC technician at least once a year, preferably before the start of the cooling season. This will help identify potential issues and allow for necessary repairs or adjustments. Regular maintenance can extend the life of your AC unit and prevent costly breakdowns.

By following these HVAC tips, you can improve the performance of your AC unit and avoid breakdowns. Contact a professional HVAC technician for regular maintenance and repair services to ensure your AC is running smoothly throughout the summer months. Consult your trusted local experts now!
