"My husband and I highly recommend Jeremy. We had power issues and Jeremy walked us through everything that was going on. He went over the pricing and stuck to it. He is quick to respond to communication. We are very happy with the work he and Austin did to correct and upgrade our electric service. We will definitely be using him for future electricity needs and recommend him highly!"

"Cawiamca Heating, Cooling, and Electrical was professional, knowledgeable and nice from the very first call. The owner Ron came out within a day to scope out the project and provide very reasonable quotes. From there, he quickly scheduled the install of the new Furnance and had his team out very quickly. His team worked diligently, were knowledgeable and very nice. They were efficient and clean during the install, leaving no debris leftover. I would highly recommend using this company as I know I will continue to going forward."

Electrical questions, answered by experts

While the line can't be removed, a pro can place a cap on the end to stop leaks. Contact a pro for a service call and speak with them about the related costs of either capping or removing the line altogether. Capping a gas line will cost between $75 and $150 while removing it will start at $250.

GFCI outlets generally need to be replaced every 7 to 15 years, though some may fail in as little as 5 years, depending on usage. It is important to test them regularly. Signs that a GFCI outlet is failing or has reached the end of its lifespan include: no power coming from the outlet, the outlet not resetting when the 'reset' button is pressed, or the outlet not tripping when the 'test' button is pressed. If you notice any of these issues, it is time to replace the outlet, and it's best to contact an electrician to do so.

It’s recommended that you test GFCI outlets monthly with the test and reset buttons. At minimum, you should test GFCI outlets when entering a new season, or every three months. These are important home safety features that you should ensure work properly.

No, it doesn’t matter which of the two wires goes on each of the two switch terminals. Just be sure to put the ground wire in the correct terminal. The ground wire is either green, bare copper, or green with a yellow stripe. The other wires are hot wires and are typically black. They can be used interchangeably.

The NEC prohibits the installation of electrical panels within clothing closets. Closets are filled with flammable items like clothing, mothballs, shoe polish, plastic containers, and exposed light bulbs. If the panel develops a small electrical fire, it won’t take long to bloom into a real disaster. If you have an electrical panel in one of your home’s closets, move it as soon as possible with the help of a professional electrician.
