Why do my Lights Flicker when the Air Conditioner Turns On?

By /

Flickering or dimming lights when your air conditioner turns on is a common sign that your home’s wiring may be undersized or deteriorating. Because high-wattage appliances like air conditioners draw a significant amount of power, they can overwhelm aging infrastructure that was not designed to handle modern electrical loads.

This occurrence is more than just a nuisance; it indicates that your electrical system is struggling to meet demand, which can lead to several risks:

  • Potential Overheating: When wiring is overtaxed, it can generate excessive heat that damages sensitive electronics and increases the risk of residential electrical fires.
  • Insufficient Capacity: Your current system or electrical panel may lack the capacity to support your home’s modern appliances.
  • Loose Connections: Flickering can also be caused by loose or deteriorating connections within your circuits that become apparent when a high-draw device starts up.

Our fully trained technicians provide comprehensive Electrical Rewiring Services and Electric Panel Upgrades to ensure your home meets all current electrical codes.

Coastal Flood Alert

Saltwater Can Leave an Electrical Hazard Behind

Our electricians advise against reusing equipment exposed to seawater simply because it has dried. Salt residue remains conductive and highly corrosive long after the water recedes.

Immediate Threat: For fire, electrical shock, or an immediate hazard, move away to safety and call 911 immediately.
Saltwater Impact & Safety Protocol
⚠️ Coastal Flooding Assessment: After coastal flooding, a qualified electrician should evaluate affected outlets, breakers, and wiring to determine what components must be replaced.
⚠️ Surge Protection Limitations: Note that surge protection does not protect electrical equipment from floodwater damage.
✓ Pre-Storm Inspections: Before future severe weather, ask an electrician to check outdoor electrical equipment and existing wiring concerns while conditions are safe.
