Many things in your home depend on electricity—from charging your electronics to keeping the temperature inside where you want it. That’s why it’s frustrating when electricity in our homes doesn’t work the way we anticipate. For many homeowners, this stress can come to a head when lights flicker after their heating and cooling system starts to run.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles show a serious electrical problem? It differs depending on the situation.
When are dimming or flickering lights considered common?
If you’re experiencing dimming that lasts for a fraction of a second when your HVAC starts, it probably isn’t something to be worried about.
While it might not feel like it, your home has a limited amount of electricity it can use at any given time. Large appliances—like your HVAC system—need a major amount of electricity to start up. When those appliances turn on, they take a larger amount of the available electricity. This means the other appliances in your home, like your lights, don’t have as much power available to them.
If this is the only issue you are facing, your lights should dim for less than a second and quickly return to full brightness. If you’re irritated by the flickering, schedule an appointment with Air Concepts of Middle Georgia. We’ll review your system and see if an equipment upgrade or circuit changes can solve the problem.
When should I be concerned about flickering lights?
Flickering lights can also signify a more serious matter. Don’t assess the situation yourself. The problem could be dangerous for you or your home. Call a professional if you see:
- Lights that continue to flicker. The normal flickering that takes place when there isn’t enough power to support all appliances in your home should last a fraction of a second. If your lights continue to flicker on and off when you start your HVAC system—or regularly at any other time—you could have an issue with your wiring.
- Lights that dim significantly. When you experience typical dimming, the effect is enough that you notice a small, brief change. If the intensity of your lights suddenly drops considerably, you could have something wrong with the outdoor compressor on your air conditioner.
- A circuit breaker trip when you turn on your HVAC. Circuit breakers are a critical part of your home’s electrical system. When they trip and shut off power to a part of your home (powered by a specific circuit), they are attempting to protect you from a problem with your circuit. While it could be that you have too many appliances on the same circuit, it’s wise to bring a professional in to check that there isn’t a more serious problem.
