Can flickering lights indicate a serious electrical problem

From charging your electronic devices to keeping a comfortable temperature inside your house, we need electricity.

That’s why it’s frustrating when the electricity doesn’t function as expected.

If the lights flicker after the air conditioning system or furnace starts, it can cause homeowners’ stress. Does dimming or flickering lights when you turn on the HVAC system indicate a severe electrical problem? It depends. When your HVAC unit starts up, you may notice a dimming that lasts for a second. Your house has a regulated amount of electricity that it can use at a time. You need a lot of electricity to start larger appliances, like your air conditioning system. Those appliances use more electricity when they are turned on. Your smaller appliances, like your lights, will not need as much power. If flickering is the only issue, your lights should only dim for a second and then immediately return to full brightness. If your light constantly flickers, it may indicate a more severe problem. Don’t investigate it for yourself as it could be dangerous. Instead, if your lights continue to flicker, dim significantly, or trip the circuit breaker, contact a professional. When there isn’t enough power to support all the appliances in your home, there will be some flickering. However, a wiring issue could be the cause of flickering lights when you start your HVAC system. The effect of dimming is enough to make you notice a small change. There may be something wrong with the outdoor condenser on your air conditioning system if your lights dim. Your home’s electrical system relies on circuit breakers. So, if they trip and shut down the power in your house, they are protecting you from a potential problem with your electrical circuit.
