Quick Answer

When half the house goes dark, your home has usually lost one of the two legs of power that feed it, either on the power company's side or at a loose connection, a failed main breaker or a burned spot inside your panel. Check your breakers and ask a neighbor if their power is normal; if it is, and resetting the main does not fix it, call a licensed electrician.

Half the lights work, the other half don't, and the AC or dryer won't start at all. I get this call often around Raleigh, Wake Forest, Durham and Cary, and it worries people because it doesn't look like a normal outage. It isn't one. Your home is fed by two legs of power, and when one goes missing, half your circuits go with it. This guide walks you through what that means, the few things you can safely check, the signs that make it an emergency and what happens when I come out to find the cause.

Why does only half the house lose power?

Key points
  • Some rooms dark, others normal
  • Heat pump, dryer or range not running
  • Lights that dim when something turns on
  • Breakers that look normal but circuits stay dead

Most homes get power through two hot wires, often called legs, plus a neutral. Your panel splits its breakers between the two legs, so the circuits on one leg can keep working while the circuits on the other go dead. That is why the kitchen lights may work while the bedrooms are dark, and why it seems random from room to room.

Big appliances like the heat pump, water heater, dryer and range use both legs at once. When one leg is missing, they often stop completely or act strangely, even though some outlets in the same room still work. That pattern, part of the house on and the big loads off, is the clearest sign you have lost a leg rather than a single circuit.

Is the problem on the power company's side or inside your home?

The missing leg can be lost anywhere along the path: the line from the pole or the underground feed, the meter, the main breaker or a connection inside the panel. The power company usually handles the line to your house and the meter. Everything from the meter base into your panel and circuits is the homeowner's side, and that is where a licensed electrician comes in.

A quick way to narrow it down is to ask a neighbor or two on the same street. If they have the same half-power problem, call your power company first. If their homes are normal and yours is not, the fault is more likely at your service, your meter base or your panel, and it is worth having it checked before it gets worse.

Where the missing leg usually is

Power company side

Call them first

  • Neighbors on the street have the same problem
  • Storm damage to the line or the pole
  • A problem at the meter itself

They handle the line to your house and usually the meter.

Inside your home

Call a licensed electrician

  • Neighbors have normal power
  • A failed or loose main breaker
  • A loose or burned connection in the panel or meter base

From the meter base to your breakers is the homeowner's side.

What you can safely check yourself

Key points
  • Ask a neighbor if their power is normal
  • Look for a tripped or middle-position breaker
  • Reset that breaker once, firmly off then on
  • Reset the main breaker once
  • Never open the panel cover or touch the meter

Start at your panel. Look for a breaker that sits in the middle position or looks different from the rest. Push it firmly to off, then back to on. Do the same once with the main breaker. A double-pole breaker that has tripped on one side only can sometimes cause the same half-dead pattern, and resetting it is safe to try once.

Stop there. Don't remove the panel cover, don't touch the meter and don't try to tighten anything. The connections that cause this problem carry power even when the main breaker is off, and the service wires coming in from the street can't be shut off from inside the house. If one reset doesn't bring everything back, the cause is past what a homeowner should handle.

Half the house out: how urgent is it?

  1. Are the lights that still work dimmer or brighter than normal, or flickering?
  2. Did resetting the breakers and the main fail to bring the power back?
  3. Is your heat pump, dryer or range dead while some outlets still work?
  4. Do you smell burning or hear buzzing at the panel or meter?
Answer the questions above

When half power becomes an emergency

Key points
  • Lights brightening or flickering up and down
  • Burning smell near the panel or meter
  • Buzzing or crackling sounds
  • A warm panel cover or scorch marks

Some half-power calls are a loose connection that can wait a short while. Others are dangerous. If the lights that still work get brighter when something else turns off, or flicker up and down, the problem may be a failing neutral rather than a missing leg. That can push too much voltage into some circuits and damage electronics and appliances quickly.

A burning smell, buzzing or crackling at the panel or meter, a panel cover that feels warm, or scorch marks anywhere near the service all mean a connection is overheating. In those cases, turn off the main breaker if you can reach it safely, unplug sensitive electronics and call for emergency help. Don't wait to see if it settles down.

What happens when I come out, and what it costs

When I arrive, I test both legs at the meter base and at the main breaker to see where the power stops. That tells us right away whether it is a power company problem or something on your side. If it is yours, I look for the loose lug, the failed main breaker or the burned connection, show you what I found and explain the fix before any work starts.

The diagnostic visit to find the cause is a flat $89, and I tell you that before booking. If you approve the repair, the $89 is typically credited toward it. A single breaker or connection repair runs $180–$360, and most repairs, diagnosis included, fall between $180 and $600. After hours, on weekends and holidays, the emergency dispatch is $149 for a home, waived when the repair is approved, and emergency repairs start at $360.

From the call to the fix

  1. On the phone

    We talk it through

    I ask what's working, what isn't and whether your neighbors have power.

  2. On arrival

    Testing both legs

    I measure at the meter base and main breaker to find where the power stops.

  3. Before any work

    You see the cause and the price

    I show you the problem and explain the repair, so you decide.

  4. The repair

    Fix and retest

    I make the repair, then test every circuit so both halves of the house have power again.

Most repairs, diagnosis included

Typical repair cost$180–$600
$180$600

A single breaker or connection repair runs $180–$360. Emergency repairs start at $360.

Frequently Asked Questions

Why did I lose power to half my house?

Your home is fed by two legs of power, and your breakers are split between them. When one leg goes missing, every circuit on that leg goes dead while the others keep working. The cause can be on the power company's line or meter, or inside your home at the main breaker, the meter base or a loose connection in the panel.

Should I call the power company or an electrician first?

Ask a neighbor or two whether their power is normal. If they have the same problem, call the power company first, because the issue is likely on their line. If your neighbors are fine and resetting your breakers didn't help, the problem is more likely on your side, and a licensed electrician should find it.

Can a tripped breaker cause half the house to lose power?

Sometimes. A main breaker or a large double-pole breaker that has failed or tripped on one side can leave half the circuits dead. Push the breaker firmly to off and back on once. If the power doesn't return, or the breaker won't stay on, leave it off and call, because the breaker or its connection may be damaged.

Why are some lights brighter than normal?

Lights getting brighter, or flickering up and down when something else turns on, can mean a failing neutral connection. That can send too much voltage to some circuits and damage electronics and appliances. Turn off the main breaker if you can reach it safely, unplug sensitive devices and call a licensed electrician as an emergency.

Why won't my AC or dryer run when some outlets still work?

Heat pumps, dryers, ranges and water heaters use both legs of power at the same time. When one leg is missing, these appliances often stop completely or run poorly, even though ordinary outlets on the working leg still have power. That pattern is a strong sign you have lost a leg rather than a single circuit.

How much does it cost to fix half the house losing power?

The diagnostic visit to find the cause is a flat $89, disclosed before booking and typically credited toward the repair you approve. A single breaker or connection repair runs $180–$360, and most repairs, diagnosis included, are $180–$600. After hours, weekends and holidays, emergency dispatch is $149 for a home, waived when the repair is approved.

Is it safe to keep using the half that still works?

If there is no burning smell, no buzzing and the lights look normal, using the working circuits for a short time is usually fine while you arrange a visit. If lights are surging, flickering or anything smells hot, turn off the main breaker and call right away. A loose connection that is heating up only gets worse.

Can I tighten the connections in my panel myself?

No. The service wires and the lugs they connect to stay energized even with the main breaker off, and they can't be shut off from inside the house. Opening the panel cover and working on those connections risks a serious shock or arc. This is a job for a licensed electrician with the right testing tools.
