Most things in your home depend 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 expect. 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 normal?
If you’re seeing dimming that lasts for a fraction of a second when your HVAC begins, it usually 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 major 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, have a lower amount of 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 tired of the flickering, schedule an appointment with Air Quality Solutions. We’ll review your system and see if an equipment upgrade or circuit changes can alleviate the problem.
When should I take action about the flickering lights?
Flickering lights can also point to a more serious matter. Don’t try to figure this out by yourself. The problem could be hazardous for you or your home. Contact a professional if you see:
- 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 a challenge with your wiring.
- Lights that dim considerably. When you experience typical dimming, the effect is enough that you notice a small, brief change. If the intensity of your lights abruptly drops considerably, you might 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 a part of your home (powered by a specific circuit), they are attempting to protect you from a concern with your circuit. While it may be that you have too many appliances on the same circuit, it’s best to bring a professional in to confirm there isn’t a more serious problem.
