My Lights Flicker When I Use My HVAC. Should I be Concerned?
Most things in your home run 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 heating and cooling system starts to kick in.
The question remains: Do dimming or flickering lights at the beginning of HVAC cycles indicate a serious electrical problem? It varies.
When are dimming or flickering lights considered usual?
If you’re experiencing dimming that lasts for a fraction of a second when your HVAC begins, it probably 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 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 a lower amount of power available to them.
If this is the lone 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 Abilene Air-Tech 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 signify a more serious matter. Don’t try to figure this out by yourself. The problem could be hazardous for you or your home. Call a professional if you notice:
- 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 regularly at any other time—you could have a challenge 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 start 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 home (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.
