Lots of 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 anticipate. 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 depends.
When are dimming or flickering lights considered normal?
If you’re experiencing dimming that lasts for a fraction of a second when your HVAC begins, it probably isn’t something to be stressed 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 substantial 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, have less power available to them.
If this is the lone 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 Airmax Long Island Inc. We’ll assess the situation and see if an equipment upgrade or circuit changes can help the problem.
When should I worry about flickering lights?
Flickering lights can also point to a more serious matter. Don’t investigate yourself. The problem could be unsafe for you or your home. Contact a professional if you see:
- Lights that continue to flicker. The normal flickering that happens 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 normal 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 turn on your HVAC. Circuit breakers are an essential 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 problem 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 check that there isn’t a more serious problem.
