Why Is Half My House Without Power? Common Electrical Issues Explained

It’s a stressful situation — half of your house has power, while the other half is completely dark. Before you panic, know that this is a common electrical problem San Antonio homeowners face. Let’s break down the most likely causes and what you can do next.

1. Tripped Breaker

The most common reason is a tripped breaker. Modern homes are split into multiple circuits, so if one breaker trips, part of your home may lose power while the rest is unaffected. Resetting the breaker in your electrical panel may solve the problem.

2. Faulty Breaker or Panel

If the breaker won’t reset or keeps tripping, the issue could be a failing breaker or even your entire electrical panel. In older San Antonio homes, outdated panels are a frequent culprit and may need replacement.

3. Loose or Damaged Wiring

Sometimes, a wiring connection comes loose or gets damaged, especially in attics or walls. This can cut power to part of your house and may even pose a fire risk. In this case, you’ll need a licensed electrician to make repairs safely.

4. Utility Company Problem

If neighbors are experiencing the same issue, it could be on the utility company’s side. Storms, blown transformers, or utility line damage can all cause partial outages. Call CPS Energy to check before scheduling service.

When to Call an Electrician

If resetting your breaker doesn’t fix the issue, or if you notice burning smells, buzzing sounds, or hot outlets, call an electrician right away. Electrical issues are dangerous if ignored.
