6 Common Causes of AC Breakdowns and How to Prevent Them

woman-in-front-of-fan-hand-on-head

When you rely on your air conditioning system throughout much of the year, an unexpected breakdown is always a frustrating experience. Unfortunately, it’s because of this heavy usage that homeowners eventually find themselves needing air conditioning repair in Orange County.

Many homeowners wonder what they could’ve done to prevent repair needs. Although even the best-maintained AC systems might need a repair every now and then, there are things you can do to decrease the likelihood of an interruption of your AC system’s cooling power. Let’s go over the most common causes of AC breakdowns and what you can do to try and prevent them. 

1. Lack of Regular Maintenance

This is the top cause of AC breakdowns. We are often called to homes where the AC system isn’t working and it’s evident the air conditioner has not received routine maintenance. Any complex piece of equipment needs to be maintained on a regular basis in order for it to function properly. 

That’s why we make it easy to schedule maintenance with our MVP Membership Value Plan maintenance club. We offer three plans that save you money, helping to ensure the value and efficiency of your home’s AC system. Membership has its value.

2. Clogged Filter

The filter in an AC system is designed to keep dust and dirt out of the internal components of the system. This filter should be replaced every 1–3 months. Failure to clean or change the filter will cause symptoms such as weak airflow, lukewarm air, and frozen coils. If your system is showing any of these signs, the first thing you should do is check the filter to see if it’s clogged or dirty.

3. Refrigerant Leaks

Refrigerant leaks are the most common cause of an AC breakdown. Although an AC was designed to have enough refrigerant to run for its entire lifespan, even the tiniest leak can result in issues. These leaks can be caused by anything from an improper installation to general wear and tear. Without enough refrigerant, the air conditioning system will never be able to function properly. Our technicians will find the source of the leak and repair it.

4. Electrical Issues

Electrical problems don’t happen often, but they can be a cause of an AC breakdown. Faulty wiring, tripped circuit breakers, and capacitor failures can disrupt the operation of the system. These problems can cause the AC unit to stop working altogether or function intermittently.

5. Thermostat Problems

A malfunctioning thermostat can cause the system to cycle on and off incorrectly or fail to maintain the desired temperature. Common thermostat problems include incorrect calibration, dead batteries, and sensor issues.

6. Frozen AC Coils

Dirty or frozen coils can significantly affect the performance of your AC system. When coils are covered in dirt or ice, they cannot effectively absorb or release heat, leading to reduced cooling capacity and potential system failure. This is something that can be caused by a lack of routine maintenance or a dirty air filter.
