Many things in your home rely on electricity—from charging your electronics 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 heating and cooling 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 varies.
When are dimming or flickering lights considered common?
If you’re experiencing dimming that lasts for a fraction of a second when your HVAC starts, it probably isn’t something to be stressed 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 consume 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 Enertek Air Conditioning & Heating. We’ll assess the situation and see if an equipment upgrade or circuit changes can help the problem.
When should I take action about the flickering lights?
Flickering lights can also signify a more serious matter. Don’t assess the situation yourself. The problem could be hazardous for you or your home. Reach out to a professional if you see:
- 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 consistently at any other time—you could have an issue 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 suddenly drops considerably, you may have something wrong with the outdoor compressor on your air conditioner.
- A circuit breaker trip when you start your HVAC. Circuit breakers are a key 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 an issue with your circuit. While it could be that you have too many appliances on the same circuit, it’s smart to bring a professional in to check that there isn’t a more serious problem.
