Lots of things in your home depend on electricity—from charging your cellphone 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 anticipate. For many homeowners, this stress can come to a head when lights flicker after their air conditioning or heating system starts to kick in.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles signify a serious electrical problem? It differs depending on the situation.
When are dimming or flickering lights considered normal?
If you’re seeing dimming that lasts for a fraction of a second when your HVAC kicks in, it probably isn’t something to be concerned about.
While it might not feel like it, your home has a regulated 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 single 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 West Jefferson Plumbing and Heating, Inc.. We’ll assess the situation and see if an equipment upgrade or circuit changes can solve the problem.
When should I be concerned about flickering lights?
Flickering lights can also point to 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 happens 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 challenge with your wiring.
- Lights that dim drastically. 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 could have something wrong with the outdoor compressor on your air conditioner.
- A circuit breaker trip when you start 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 space (powered by a specific circuit), they are attempting to protect you from a problem 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 make sure there isn’t a more serious problem.
