Imagine this: A sudden storm knocks out power in your area, and when it finally comes back, your air conditioner won’t start. You’re stuck in the sweltering heat, wondering what went wrong. 

In this guide, Trammell Heating & Air will explain your AC might not be working after a power outage, helping you understand how to address this issue effectively. For more comprehensive support, consider contacting the go-to AC repair company in Jefferson.

Three Reasons Your Air Conditioner Won’t Turn Back On

When your AC fails to restart after a power outage, several components could be to blame. Here’s a breakdown of common problems:

1. You Have a Tripped Circuit Breaker

Power surges during an outage can trip circuit breakers, cutting off power to your AC. This is often the first place to check. If you find the breaker for your AC has tripped, resetting it might solve the problem. 

To reset, switch the breaker off and then back on, keeping it in the “on” position. If it trips again shortly after resetting, this could indicate a more serious issue that requires professional attention. Regularly checking and maintaining your breaker can prevent such problems and ensure your AC runs smoothly.

2. The Compressor Failed

The compressor is essential for heat exchange and cooling your home. Unfortunately, power fluctuations can cause compressor failure, requiring professional repair or replacement to get your AC running again. Compressor issues are often signaled by strange noises or a complete lack of sound when trying to start the AC unit. If the compressor fails, it can lead to other system parts overworking, reducing the efficiency of your AC system. 

3. There’s Capacitor Damage

Capacitors provide the necessary start-up energy for your compressor and motors. A power surge can damage these components, preventing your AC from starting. Inspecting and replacing a damaged capacitor is a task for skilled technicians.

If you suspect capacitor issues, do not attempt repairs yourself, as this could lead to further damage or personal injury. A technician will test the capacitor’s performance and replace it if needed to ensure the optimal functioning of your AC. Regular testing of the capacitor as part of routine AC maintenance can help catch issues before they lead to a breakdown.

What You Can Do To Get It Back On

If you have an AC not working after a power outage, the potential causes we mentioned above typically require professional attention. But before you call the experts, you can try a few troubleshooting steps to kickstart your air conditioning at home.

Thermostat Reset

Check your thermostat. Sometimes, settings are lost, or it disconnects from Wi-Fi. Resetting it could be enough to reactivate your AC. If your thermostat remains unresponsive after a reset, ensure it is receiving power and that its batteries, if applicable, are fresh.

Power Surge Effects

After a surge, ensure no components were permanently damaged. These might include wiring or other electrical components. Inspecting your AC system for fried wires or charred components can prevent potential hazards. It’s crucial to address these damages promptly to restore safe and efficient operation.

HVAC System Inspection

It’s beneficial to have professionals inspect your system to avoid future issues. A thorough inspection can identify and rectify minor problems before they escalate into costly repairs. Regular checks by a professional can extend the lifespan of your AC, ensuring it performs optimally through the heat.
