"Michael showed up right on time, removed the old light fixture, installed the new one. He cleaned up the small mess that was made with the project and took the old fixture out with him when he left to dispose of. The pricing was fair and I have absolutely no complaints with the technician that came to do the project or Supreme Electric & will use them again on future projects."

Electrical questions, answered by experts

Installing a circuit breaker is best handled by a local professional electrician. This project requires following strict electrical codes, and might even involve permits. Not only can electrical work be dangerous, but without the proper training that a pro will have, you could cause further damage to your home’s electrical system.

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).

Different types of light switches include single-pole switches (the standard switch in your home), double-pole switches, toggle switches, three-way switches, four-way switches, dimmer switches, and more. 

A single-pole light switch controls the power to a single device, whereas two-way, three-way, and four-way light switches control lights from different locations, increasing the number of connections in the home.

The size of your home will help determine the size of your electrical panel. Usually, the decision comes down to a 100-amp electrical panel versus a 200-amp panel. Smaller homes, especially those without an HVAC system, may be able to get by with a 100-amp panel. 

If you have a larger home or need to power AC, a 200-amp panel should be the best fit. It’s unlikely that you’ll need a larger panel than that unless you have a larger home or unique electrical needs, but an electrician can help you make the final call.

Hiring a professional for attic fan installation or replacement is highly recommended to ensure safety, proper ventilation, and effectiveness without damaging your roof. The type of professional needed can vary based on the fan type and project specifics.

  • HVAC Technicians: They understand airflow and ventilation principles, making them well-suited for the job.

  • Roofers: Experienced roofers are ideal for roof-mounted fans, as they can ensure a watertight installation.

  • Electricians: A licensed electrician is essential if new wiring is needed, or for replacing solar or electric attic fans to safely handle the electrical connections.

  • Carpenters: They may be needed to install gable vent fans or to ensure a new fan fits the existing structure correctly.

  • Handyperson: For a simple replacement of an old fan with no wiring or structural modifications, a handyperson might be an option.
