Lots of things in your home run 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 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 operate.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles show a serious electrical problem? It varies.
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 regulated amount of electricity it can use at any given time. Large appliances—like your HVAC system—need a substantial 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 irritated by the flickering, schedule an appointment with Ohler & Holzhauer Inc.. We’ll review your system and see if an equipment upgrade or circuit changes can help the problem.
When should I take action about the flickering lights?
Flickering lights can also indicate a more serious matter. Don’t assess the situation yourself. The problem could be dangerous for you or your home. Reach out to a professional if you see:
- Lights that continue to flicker. The normal flickering that happens when there isn’t enough power to accommodate 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 continually at any other time—you could have a problem with your wiring.
- Lights that dim drastically. 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 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 a section of your home (powered by a specific circuit), they are attempting to protect you from a concern with your circuit. While it might be that you have too many appliances on the same circuit, it’s best to bring a professional in to check that there isn’t a more serious problem.
