Many things in your home run 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 HVAC system starts to operate.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles show a serious electrical problem? It differs depending on the situation.
When are dimming or flickering lights considered common?
If you’re experiencing dimming that lasts for a fraction of a second when your HVAC kicks in, it likely isn’t something to be worried 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, 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 irritated by the flickering, schedule an appointment with Point Heating & Cooling. We’ll review your system 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 try to figure this out by yourself. The problem could be dangerous 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 problem with your wiring.
- Lights that dim drastically. When you experience usual dimming, the effect is enough that you notice a small, brief change. If the intensity of your lights suddenly drops considerably, you might have something wrong with the outdoor compressor on your air conditioner.
- A circuit breaker trip when you switch on your HVAC. Circuit breakers are a critical part of your home’s electrical system. When they trip and shut off power to a part of your house (powered by a specific circuit), they are attempting to protect you from an issue 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 check that there isn’t a more serious problem.
