"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

A low-voltage landscape lighting system using 15 to 20 LED lights for six hours a night will average about $5 to $10 a month in electricity costs. This is considered affordable lighting for many homeowners. Most modern landscape lights use LED bulbs, but some older styles may use halogen or incandescent bulbs, which can cost up to five times more than LEDs in electrical costs.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

Christmas lights typically do not need to be grounded like electrical circuits in your home do. However, it's crucial to use outdoor outlets equipped with ground fault circuit interrupters (GFCIs) for added safety. GFCIs can help protect against electrical shocks and are recommended for outdoor electrical connections when using Christmas lights.

Single switch installs are quick DIY projects, but you should consider enlisting the help of a pro for more complicated replacements—like a smart switch or if you live in an older home with outdated wiring. Professional electricians are trained in the latest code regulations. They are also insured, licensed, and bonded.

For more complex electrical projects, it’s often most efficient and cost-effective to hire an electrician rather than trying to figure it out yourself (and risking electrical problems). Electricians know exactly what a project requires, and can often find supplies or parts for cheaper than the average homeowner. That can save money compared to going it alone.
