Lots of 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 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 signify 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 kicks in, it probably isn’t something to be concerned 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, have less 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 irritated by the flickering, schedule an appointment with Comfort Concepts Heating & Air Conditioning. We’ll review your system and see if an equipment upgrade or circuit changes can help the problem.
When should I worry 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 experience:
- Lights that continue to flicker. The normal flickering that takes place 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 continually at any other time—you could have an issue 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 suddenly 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 section of your space (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 wise to bring a professional in to check that there isn’t a more serious problem.
