Imagine it’s a sweltering August afternoon in Durham, NC, with temperatures soaring above 90°F. Your air conditioner, which has been working overtime to keep your home cool, suddenly stops functioning. As the humidity rises, so does your concern. In Durham, where summer heatwaves are a yearly challenge, an AC failure can quickly escalate from uncomfortable to unbearable. This article will guide you through the immediate steps to take when your AC fails during a heatwave, the common causes, and when to call a professional for help.
Immediate Steps to Take
A. Check the Thermostat
One of the first things to check when your AC stops working is the thermostat. Ensure it’s set to “cool” and that the temperature is properly adjusted. Sometimes, a simple mistake like having the thermostat set to “heat” can be the culprit. Also, verify that the thermostat has power—if it runs on batteries, they might be dead and need replacing.
B. Inspect the Circuit Breaker
Next, check your home’s circuit breaker. High energy demand during a heatwave can sometimes trip the breaker. If the AC unit’s breaker has tripped, reset it by flipping the switch off and then back on. However, if the breaker trips again immediately, it’s a sign of a more significant issue, and you should avoid repeatedly resetting it.
C. Examine the Air Filter
A clogged air filter can restrict airflow, causing the AC to shut down to prevent damage. Inspect the filter, and if it’s dirty, replace it. It’s a simple fix, but it can make a big difference in your system’s performance, especially during peak usage times.
D. Look for Ice on the Unit
If you notice ice buildup on your AC unit, particularly on the evaporator coils, it could be the reason your AC has stopped working. Ice can form due to low refrigerant levels or restricted airflow. Turn off the AC and allow it to thaw as a temporary measure, but know that this issue likely requires professional attention.
III. Common Causes of AC Failure During Heatwaves
A. Overworked System
During a heatwave, your AC is likely running almost non-stop to keep up with the high temperatures. This constant operation can cause the system to overheat and shut down. Ensuring that your system is appropriately sized for your home and maintaining it regularly can help prevent this.
B. Refrigerant Leaks
Refrigerant is essential for cooling the air in your AC unit. If there’s a leak, the system can’t effectively cool your home and may eventually stop working. Signs of a refrigerant leak include ice on the evaporator coils, hissing noises, and poor cooling performance.
C. Electrical Issues
The electrical components of your AC, such as capacitors and wiring, can fail due to the high demand placed on them during extreme heat. If your AC is experiencing electrical issues, it’s best to call a professional to diagnose and repair the problem safely.
D. Dirty Condenser Coils
The condenser coils in your outdoor unit are responsible for releasing the heat removed from your home. If they’re covered in dirt and debris, they can’t do their job effectively, causing the system to overheat and shut down.
IV. When to Call a Professional
A. Persistent Issues After Basic Troubleshooting
If you’ve gone through the basic checks and your AC is still not working, it’s time to call in a professional. Continuing to run a malfunctioning unit can lead to more significant damage and higher repair costs.
B. Signs of Major Problems
Certain issues, like strange noises, foul odors, or water leakage, are clear indicators that something is seriously wrong with your AC. These are problems that require the expertise of a certified HVAC technician to address.
C. Importance of Professional Diagnosis
An HVAC professional can accurately diagnose the problem and perform the necessary repairs to get your system running again. They have the tools and experience to handle complex issues that a typical homeowner wouldn’t be able to fix on their own.
V. Preventative Measures for the Future
A. Regular Maintenance
Scheduling regular AC maintenance, particularly before the summer season in Durham, is one of the best ways to prevent unexpected breakdowns. During a maintenance visit, a technician will clean the unit, check refrigerant levels, inspect electrical components, and ensure everything is running smoothly.
B. Energy-Efficient Practices
To reduce the strain on your AC, consider using energy-efficient practices, such as closing blinds during the hottest part of the day, using ceiling fans to circulate air, and setting the thermostat to a higher temperature when you’re not home.
C. Consider Upgrading Your System
If your AC unit is frequently breaking down, it may be time to consider upgrading to a newer, more efficient model. Modern AC systems are designed to handle extreme heat better and operate more efficiently, which can save you money on energy bills and reduce the risk of future failures.
