As summer heats up in Lee’s Summit, MO, a functioning air conditioning system is crucial for comfort. But what happens when your AC unit suddenly fails? Understanding the common causes of AC breakdowns can help you maintain your system and keep your home cool.

Dirty or Clogged Filters

One of the most common reasons for AC failure is dirty or clogged filters. When filters aren’t cleaned or replaced regularly, they can obstruct airflow, reducing the system’s efficiency. This blockage forces your unit to work harder, leading to increased wear and tear and eventually causing the system to overheat or shut down.

Refrigerant Leaks

Your AC system relies on refrigerant to cool your home. If there’s a leak, your AC can’t effectively cool the air. Not only does this result in insufficient cooling, but it also causes your AC to run continuously, stressing the components and leading to a complete breakdown. If you notice reduced cooling, it might be due to a refrigerant leak.

Electrical Issues

Faulty wiring, damaged capacitors, and other electrical issues can prevent your AC from functioning properly. Electrical problems often result from wear over time or external factors like power surges. Regular maintenance checks can identify and resolve these issues before they cause significant damage to your AC unit.

Thermostat Problems

Sometimes, the issue isn’t with your AC unit at all but with the thermostat controlling it. If the thermostat is malfunctioning or improperly calibrated, your AC might not operate correctly. This can lead to inconsistent temperatures or the system not turning on at all. Ensuring your thermostat is in good working order can prevent unnecessary AC problems.

Blocked Condenser Coils

Condenser coils in your outdoor unit can accumulate dirt, leaves, and other debris. When these coils become blocked, heat transfer is impeded, and your AC unit has to work harder to cool your home. Regularly cleaning the area around your outdoor unit can prevent this issue and keep your AC running smoothly.

Poor Maintenance

Regular maintenance is essential for the longevity and efficiency of your AC unit. Neglecting routine inspections, cleanings, and tune-ups can lead to unnoticed problems that escalate into significant failures. Investing in annual maintenance can catch minor issues before they become costly air conditioning repairs.
