Why Houston Homeowners Need an Electrical Panel Upgrade
Houston homes frequently experience surges in electrical demand. New appliances, smart home systems, EV chargers, and larger HVAC units are common, but older electrical panels may not accommodate these new loads. Upgrading your panel allows your electrical system to handle increased capacity safely and protects your home from common issues caused by outdated equipment.
Key Houston factors influencing panel upgrades:
- High summer cooling loads: Prolonged AC use places heavy demand on circuits.
- Aging housing stock: Many Houston homes have panels installed decades ago.
- New technology adoption: Electric vehicles, home automation, and high-powered appliances require modern panels.
- Local electrical codes: Houston’s evolving building codes require code-compliant panel upgrades.
Signs You Need an Electrical Panel Upgrade
Recognizing the warning signs that your electrical panel needs upgrading is crucial to preventing dangerous problems. Mackey Services helps Houston residents identify these issues through thorough capacity evaluations.
Common signs a panel upgrade is necessary include:
- Frequent circuit breaker trips: Overloaded panels struggle to handle current demands.
- Flickering or dimming lights: Voltage drops indicate strain on your electrical system.
- Burning smells or scorch marks: Evidence of arcing or overheating, a fire hazard.
- Panel is hot to the touch: Excessive heat signals unsafe electrical connections.
- Use of multiple extension cords: Sign of inadequate capacity for household needs.
- Having fuse boxes or panels under 60 amps: Modern homes typically require at least 100 amps.
If your Houston home experiences any of these signs, an electrical panel upgrade by Mackey Services will enhance your system’s safety and performance.
