Get matched with top electricians in Unicoi, TN

Yes, electricians must be licensed, certified, and in most cases, insured. Licensing requirements vary by state and local municipality, but most U.S. municipalities require electricians to hold an electrical contractor’s license. It's always a good practice to confirm requirements with your local municipality. Even if licensing is not required in your area, hiring a licensed and experienced electrician often leads to a better end result.

A license is a legal requirement to operate a business and is necessary for pulling project permits. Certifications, on the other hand, are typically voluntary and demonstrate a certain level of expertise. In some cases, a certified electrician may send an apprentice or journeyman to perform the work, but they must operate under a primary electrician who holds the proper license.

Before hiring, you should verify the electrician's license, insurance coverage, and any third-party certifications. You can use Angi’s contractor licensing search to confirm a pro's license status. Additionally, businesses with the “Angi Approved” badge on our platform meet strict criteria, including having the required state and local licenses, passing a background check, and maintaining a high average rating.

Single-pole light switches are the most common light switches on the market. Their simple features make them easy to install and use. For more powerful applications that require 30 or 40 amps, you may need to use a double-pole switch. Some homeowners may want multi-way switches like three-way or four-way switches to control a light fixture from opposing ends of the room.

Typically, refrigerators should not be plugged into GFCI outlets. This is another appliance with a motor that can be prone to a little current leakage. Using a standard outlet saves nuisance tripping and the potential of waking up to a refrigerator full of warm food. The only exception is when the refrigerator is in a garage, where all outlets must be GFCI.

Light switches can last for decades when installed and maintained correctly. Improper wiring, heavy wear and tear, or too much wattage draw can cause light switch failure long before the expected end of a light switch’s life. Light switches that are hot to the touch, making a buzzing noise, or failing to work consistently should be inspected to find and repair the underlying cause.
