Many things in your home depend on electricity—from charging your phone 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 expect. For many homeowners, this stress can come to a head when lights flicker after their HVAC system starts to run.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles signify a serious electrical problem? It depends.
When are dimming or flickering lights considered usual?
If you’re noticing dimming that lasts for a fraction of a second when your HVAC begins, it likely isn’t something to be concerned about.
While it might not feel like it, your home has a certain amount of electricity it can use at any given time. Large appliances—like your HVAC system—need a significant amount of electricity to start up. When those appliances turn on, they consume a larger amount of the available electricity. This means the other appliances in your home, like your lights, have less power available to them.
If this is the single issue you are facing, your lights should dim for less than a second and quickly return to full brightness. If you’re done with the flickering, schedule an appointment with Branson HVAC, LLC. We’ll take a look and see if an equipment upgrade or circuit changes can solve the problem.
When should I take action about the flickering lights?
Flickering lights can also point to a more serious matter. Don’t investigate yourself. The problem could be dangerous for you or your home. Call a professional if you experience:
- 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 consistently at any other time—you could have a problem 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 unexpectedly drops considerably, you may have something wrong with the outdoor compressor on your air conditioner.
- A circuit breaker trip when you start your HVAC. Circuit breakers are a critical part of your home’s electrical system. When they trip and shut off power to an area of your space (powered by a specific circuit), they are attempting to protect you from a problem with your circuit. While it might be that you have too many appliances on the same circuit, it’s smart to bring a professional in to confirm there isn’t a more serious problem.
