Lots of things in your home depend on electricity—from charging your cell phone to keeping the temperature inside where you want it. That’s why it’s annoying when electricity in our homes doesn’t work the way we want it to. For many homeowners, this stress can come to a head when lights flicker after their air conditioning or heating system starts to kick in.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles signify a serious electrical problem? It varies.
When are dimming or flickering lights considered common?
If you’re seeing dimming that lasts for a fraction of a second when your HVAC kicks in, it likely isn’t something to be concerned about.
While it might not feel like it, your home has a regulated 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 consume a larger amount of the available electricity. This means the other appliances in your home, like your lights, have a lower amount of 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 done with the flickering, schedule an appointment with Scott Temperature. We’ll assess the situation 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 indicate a more serious matter. Don’t investigate yourself. The problem could be dangerous for you or your home. Reach out to a professional if you notice:
- Lights that continue to flicker. The normal flickering that occurs when there isn’t enough power to keep up with 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 considerably. When you experience usual dimming, the effect is enough that you notice a small, brief change. If the intensity of your lights suddenly drops considerably, you might have something wrong with the outdoor compressor on your air conditioner.
- A circuit breaker trip when you switch 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 house (powered by a specific circuit), they are attempting to protect you from an issue with your circuit. While it may be that you have too many appliances on the same circuit, it’s smart to bring a professional in to make sure there isn’t a more serious problem.
