Most 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 infuriating 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 heating and cooling 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 begins, it probably isn’t something to be concerned 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 significant amount of electricity to start up. When those appliances turn on, they use 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 tired of the flickering, schedule an appointment with All Weather Heating & Air Conditioning Inc. We’ll take a look and see if an equipment upgrade or circuit changes can help the problem.
When should I be concerned about flickering lights?
Flickering lights can also indicate a more serious matter. Don’t try to figure this out by yourself. The problem could be unsafe 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 consistently at any other time—you could have a problem with your wiring.
- Lights that dim significantly. When you experience usual dimming, the effect is enough that you notice a small, brief change. If the intensity of your lights abruptly 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 key 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 concern 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 make sure there isn’t a more serious problem.
