Why Do My Lights Flicker When the AC Turns On?
It can be concerning when the lights in your home or business start to flicker when the AC turns on. This issue can occur due to a variety of reasons and here, we’ll discuss some of the most common causes and solutions.
Shortage of Voltage
One of the most common reasons for flickering lights when the AC turns on is due to a shortage of voltage. The AC motor draws large amounts of energy just to start, which can briefly cause a decrease in the amount of voltage being supplied to the lights. This causes them to flicker and dim. This can be easily fixed by having a licensed electrician install a larger power supply that can handle the load the AC needs.
Loose Connections
When electrical connections become loose, it can cause lights to flicker on and off. This is because of an irregular connection with the electrical system. Loose connections is a common issue, especially near the AC unit due to frequent use of the switches. This problem can be fixed by a professional electrician tightening up the connections.
Old/Faulty Wiring
It’s possible that flickering lights when the AC turns on is an indication of aged or faulty wiring. If there’s any wiring that is beginning to show signs of wear, or if it hasn’t been upgraded in a while, then it’s the best course of action to call in a professional electrician.
Improperly Installed Switches
Sometimes, flickering lights when an AC turns on is due to a switch that has been incorrectly installed. This is a relatively easy fix for a professional electrician, but it will require diagnostics to understand the root cause and make the appropriate repair.
Conclusion
When lights flicker when an AC turns on, it can be due to a variety of reasons, including:
- Shortage of voltage
- Loose connections
- Old or faulty wiring
- Improperly installed switches
In such situations, the best practice is to call in a licensed electrician that can quickly identify the cause and make the necessary repairs.
3. Could the flickering lights be a symptom of an electrical issue?
Yes, flickering lights can indicate an underlying electrical issue. This can be caused by loose wiring, faulty connections, overloaded circuits, or other electrical issues. Other potential causes include malfunctioning light fixtures, bad switches, and failing circuit breakers.
5. What safety measures should I take to protect my electrical appliances from flickering lights?
The best way to protect your electrical appliances from flickering lights is to use a surge protector. This will help protect the electrical appliances from voltage or current surges that may be caused by a power outage or other types of electric interference. Additionally, it is important to make sure all electrical outlets are properly grounded and that all cords are properly maintained for optimal performance. It is also important to unplug any unnecessary appliances when not in use, as these can draw more power than necessary and can cause additional strain on the electrical system.
