Many 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 frustrating when electricity in our homes doesn’t work the way we want it to. 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 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 starts, it usually isn’t something to be stressed about.
While it might not feel like it, your home has a limited amount of electricity it can use at any given time. Large appliances—like your HVAC system—need a major 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, 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 irritated by the flickering, schedule an appointment with Hix Air Conditioning Service, Inc.. We’ll take a look and see if an equipment upgrade or circuit changes can alleviate the problem.
When should I take action about the 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. Call a professional if you see:
- Lights that continue to flicker. The normal flickering that happens 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 regularly at any other time—you could have an issue with your wiring.
- Lights that dim considerably. When you experience usual 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 a key part of your home’s electrical system. When they trip and shut off power to an area of your house (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 wise to bring a professional in to make sure there isn’t a more serious problem.
