Many things in your home run on electricity—from charging your electronics to keeping the temperature inside where you want it. That’s why it’s infuriating 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 run.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles indicate 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 starts, it usually 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 significant 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, don’t have as much 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 done with the flickering, schedule an appointment with Smyth Air Conditioning Inc. We’ll review your system and see if an equipment upgrade or circuit changes can solve 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 unsafe for you or your home. Contact a professional if you notice:
- 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 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 unexpectedly drops considerably, you may have something wrong with the outdoor compressor on your air conditioner.
- A circuit breaker trip when you switch on your HVAC. Circuit breakers are an essential part of your home’s electrical system. When they trip and shut off power to an area of your space (powered by a specific circuit), they are attempting to protect you from a concern with your circuit. While it might be that you have too many appliances on the same circuit, it’s smart to bring a professional in to make sure there isn’t a more serious problem.
