"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 multimeter does not measure frequency, charge, inductance, and other electrical quantities. Instead, it measures voltage (AC and DC), current, and resistance.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Old electrical systems may have more problems than newer ones. In some cases, like if your home has aluminum wiring, it may be necessary to update your electrical system. You should also update your home’s wiring if it still has knob and tube wiring, which is considered dangerous by modern building standards. If that applies to you, get in touch with an electrical professional near you to obtain a quote.

You should not attempt to disable a smoke alarm unless you’ve already activated a replacement unit. To stop a hardwired smoke alarm from beeping, reset the device or silence the alarm. If you’re removing a hardwired alarm, shut off the power, turn the unit counterclockwise to remove it from the ceiling, and disconnect the wiring.

If the outlet is a GFCI model, this is normal since these outlets have their own breakers that shut off when they encounter a problem—just hitting the reset button should solve the issue. Otherwise, the outlet could have bad wiring, or your circuit breaker could be having issues. If the issue started out of nowhere and is not on a GFCI outelt, it’s best to contact an electrician to diagnose the issue.
