Most things in your home depend on electricity—from charging your cellphone 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 heating and cooling system starts to kick in.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles indicate 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 begins, it usually 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 significant 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 single 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 Premium Air Services LLC. We’ll take a look and see if an equipment upgrade or circuit changes can help the problem.
When should I worry about flickering lights?
Flickering lights can also signify a more serious matter. Don’t investigate yourself. The problem could be hazardous for you or your home. Reach out to a professional if you notice:
- Lights that continue to flicker. The normal flickering that happens 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 challenge 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 could have something wrong with the outdoor compressor on your air conditioner.
- A circuit breaker trip when you switch on your HVAC. Circuit breakers are an essential 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 make sure there isn’t a more serious problem.
