Most things in your home rely 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 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 differs depending on the situation.
When are dimming or flickering lights considered normal?
If you’re experiencing dimming that lasts for a fraction of a second when your HVAC kicks in, it probably 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 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 Booneville Heating & Cooling LLC. We’ll take a look and see if an equipment upgrade or circuit changes can alleviate the problem.
When should I worry about flickering lights?
Flickering lights can also signify a more serious matter. Don’t try to figure this out by 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 takes place when there isn’t enough power to support 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 continually at any other time—you could have a challenge 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 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 a key 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 might 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.
