Lots of things in your home run on electricity—from charging your electronics 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 HVAC system starts to kick in.
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 usual?
If you’re noticing dimming that lasts for a fraction of a second when your HVAC starts, it usually isn’t something to be concerned about.
While it might not feel like it, your home has a certain 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 use 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 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 Wallpe Heating & Cooling. We’ll take a look and see if an equipment upgrade or circuit changes can alleviate the problem.
When should I be concerned about 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. Contact a professional if you notice:
- Lights that continue to flicker. The normal flickering that takes place 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 regularly 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 start 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 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.
