If you’ve noticed your lights dimming, fluttering, or flickering in your Sacramento home, you’re not alone. We get calls about this every single week at Old Town Electric, and here’s the thing: while some causes are harmless, others can signal a serious electrical problem.
In this guide, we’ll break down why lights flicker, how Sacramento’s climate and infrastructure can play a role, and when it’s time to call in a licensed electrician before a small annoyance turns into a safety hazard.

Everyday Causes of Flickering Lights
Let’s start with the basics. Not all flickering is an emergency. Sometimes, the solution is as simple as tightening a bulb.
Loose or Faulty Light Bulbs
A loose bulb can break the electrical connection, causing intermittent flickers. In older fixtures, the metal contacts can also corrode over time.
Quick check:
Turn off the power, gently tighten the bulb, and see if it helps. If it’s still flickering, try replacing the bulb with a new one.
Incompatible Light Dimmers
This one catches homeowners off guard. Many Sacramento homes still have dimmer switches designed for incandescent bulbs. If you’ve swapped to LEDs, that mismatch can cause a constant flicker.
Solution: Install a dimmer that’s rated for LED lighting.
When It’s Not So Simple: Electrical Issues Behind Flickering
Here’s where things get serious. Some flickering means your electrical system is struggling, and that’s a job for a pro.
Overloaded Circuits
Ever notice lights dimming when you run the microwave or hair dryer? That’s your circuit straining to supply enough power.
In Sacramento, we see this a lot in older homes built before the 1980s. Back then, circuits weren’t designed for the load modern appliances draw.
Risks:
Overloaded circuits can overheat, damaging wiring and increasing fire risk.
Fix:
We can install dedicated circuits for high-demand appliances or upgrade your electrical panel.
Loose Wiring Connections
Loose wiring isn’t just an inconvenience, it’s a fire hazard. According to the U.S. Fire Administration, bad electrical connections are one of the top causes of residential fires.
Signs this could be the issue:
- Flickering in multiple lights on the same circuit
- Burning smell near outlets or switches
- Warm or discolored outlet plates
If you suspect this, turn off power to the affected circuit and call a licensed Sacramento electrician immediately.
Voltage Fluctuations
Sacramento’s aging grid, combined with seasonal high demand (think: everyone’s AC running in August), can cause voltage fluctuations that make lights flicker.
We’ve seen this spike during heatwaves, especially in neighborhoods like East Sacramento, Land Park, and Arden-Arcade where older infrastructure hasn’t been fully upgraded.
If flickering happens at the same time every day, utility voltage could be the culprit.
Sacramento-Specific Factors That Cause Flickering
Living here means dealing with a few unique conditions that can affect your electrical system.
Summer Power Demand
Our hot, dry summers mean air conditioners are running almost nonstop. High demand strains both the local grid and your home’s circuits.
PG&E and SMUD Maintenance
Scheduled maintenance or grid switching can cause temporary voltage drops. While usually brief, it’s enough to make lights flicker.
Older Neighborhood Wiring
Historic homes in Midtown or Curtis Park often still have knob-and-tube wiring or outdated panels. These systems just aren’t built for today’s electrical loads.
How to Diagnose the Problem
Before you call for help, here are a few checks you can do:
- Test multiple lights.
Is it just one fixture or the whole house? - Note when it happens.
Does it occur when certain appliances are on? - Listen for buzzing.
Electrical buzzing can mean loose wiring. - Check with neighbors.
If they have the same issue, it might be a utility problem.
When to Call Old Town Electric
Some flickers are harmless. Others are a red flag.
You should call us if:
- Flickering happens in multiple rooms
- You smell burning or see scorch marks
- Lights dim dramatically when appliances start
- It’s getting worse over time
In these cases, professional inspection is the safest move.

A Real Sacramento Example
A homeowner in Carmichael called us last summer about flickering lights in the kitchen and living room. The cause? An overloaded circuit feeding both the fridge and microwave, combined with loose wiring in the panel.
We installed a dedicated line for the fridge, tightened all panel connections, and the flickering stopped instantly. The homeowner’s comment:
“I wish I’d called months ago. I didn’t realize it could have been dangerous.”
Bottom Line for Sacramento Homeowners
Flickering lights aren’t always an emergency, but they’re never something to ignore. In some cases, it’s just a bulb or a dimmer switch. In others, it’s a warning sign of serious electrical issues.
