Many 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 run.
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 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 stressed 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 substantial 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 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 Assured Appliance and Heating & Air. 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 point to a more serious matter. Don’t investigate yourself. The problem could be dangerous for you or your home. Reach out to 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 significantly. 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 an area of your house (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.
