Why Do Lights Flicker When Your AC Turns On?

If you have noticed that your lights flicker when the AC turns on, you may have serious concerns about your unit’s functionality. Is it something to worry about? And why does it happen? Fortunately, this is a common occurrence, and you shouldn’t panic. Either way, it is an excellent idea to schedule routine maintenance and air conditioner repair in Port Charlotte to detect and fix minor issues before things worsen. Here, we look at reasons why this happens and when you need to take action.

The Initial Power Surge

When an air conditioner starts, it requires significant power to get the compressor and fans running. This initial power surge can briefly draw a lot of electricity, which causes a voltage drop in your home’s electrical system. A sudden voltage drop will make your lights dim when the AC turns on. A solid solution to this problem is taking preventive measures. For instance, you can install a GFCI circuit breaker to handle these surges and mitigate potential hazards.

Electrical System Load Balancing

Your home’s electrical system distributes power evenly across various circuits. However, when a high-demand appliance like an HVAC kicks in, it can draw more energy than usual from one circuit. You are likely to notice a dim in your lights when that happens. If you are currently experiencing this problem in your home, you should think of hiring a certified technician to ensure your electrical system is balanced correctly. Doing so makes it able to handle the demands of modern appliances.

Impact of Wiring and Circuit Breakers

Your home’s wiring and circuit breakers are crucial in managing electrical loads. If your wiring is outdated or can’t handle the demands of modern appliances, your lights can blink when the AC comes on. Also, if your circuit breakers are old or not functioning correctly, they may not distribute power effectively. You can help your electrical systems manage the power demands better through timely upgrades and regular inspections by a trusted technician.

When to Seek Professional Help?

While it is normal to notice lights dimming in your house when the AC comes on, it is not a significant cause for concern. However, consistent or severe dimming can show underlying electrical issues, hence the need to consult a professional. Certified technicians can inspect your electrical system, identify potential problems, and recommend necessary upgrades or repairs to ensure your home’s electrical system functions optimally.
