Understanding the Link Between Your HVAC and Flickering Lights
In many Phoenix homes, you might notice your lights flicker briefly when your air conditioning system starts. This occurs because HVAC units demand a large surge of electrical power to start the compressor and blower motors, causing a temporary voltage drop. While some flickering during startup is normal, frequent or severe flickering signals an electrical issue that should be addressed promptly to avoid damage or safety hazards.
Common Causes of Lights Flickering When the AC Kicks On
Several factors can cause this flickering phenomenon:
- High startup current: The compressor requires a large amount of electricity to start, which can momentarily lower the voltage.
- Loose or faulty wiring: Poor electrical connections in your home or at the HVAC unit can cause inconsistent power delivery.
- Undersized electrical service: Older homes or upgrades in HVAC capacity without electrical system upgrades may not handle the load properly.
- Aging or failing circuit breakers: Breakers that trip or don’t hold current can create flickering or intermittent power.
If flickering happens frequently or worsens, it may indicate an underlying electrical problem.
When to Contact a Phoenix HVAC or Electrical Professional
If you observe:
- Flickering lasting more than a second or affecting multiple lights
- Lights dimming or flickering, unrelated to HVAC startup
- Burning smells or buzzing near outlets or your breaker panel
Call a licensed HVAC or electrician immediately. These signs can indicate serious wiring issues or potential fire hazards in Phoenix homes.
Solutions to Fix Flickering Lights Related to Your HVAC
Possible fixes include:
- Tightening or replacing loose wiring connections
- Upgrading your electrical panel or circuit breakers
- Installing a dedicated circuit for your HVAC system
