"From estimate, to selection of The Juice Company, to scheduling, they made the entire process painless. Had 2 15 amp "peanut" breakers installed to replace an existing breaker and establish a new circuit, and 2 new outlets installed. We also had low voltage network cable roughed in so I could terminate it later, and everything was done not only properly, but quickly. I would definitely recommend them to anyone needing electrical work done in the South Sound region."

"I had told them I would be buying an EV and they said to give them a ring when I was ready to install the charger. Bought the car on Saturday, called them on Monday, installed on Thursday with no drama, apparently excellent workmanship, and in a timely manner. They were even able to do it without disturbing our internet access despite having to move breakers around."

"We had In-House Electrical replace/upgrade our main panel as well as setup a generator hook-up and A/C outlet outside. Adam and Avery were phenomenal - they were thorough, kept in constant communication with me during the project to ensure things were being done as I liked, and left the place looking better than when they showed up. They'll be my first call in the future for any electrical work I need done."

"Prompt and efficient. Polite and personable. They sent a technician to help our old furnace to function on the Saturday before New Years. It held out until this last Wednesday, the 8th, when we opted to have a new furnace and heat pump system installed. Work was completed in a timely manner. The installers and electricians were outstanding in explaining new info about operations and more. Great experience!!"

"I called Voltlab and Evan Cade to advise me on what to do about some ungrounded outlets in my house. After helpful discussion during a complimentary inspection of the rest of my electrical system it was clear I needed serious attention to more than a few outlets. What I thought would be a simple service call turned into a service upgrade and partial rewire. Though I was surprised with the amount of work required to bring the house up to code, Evan's obvious knowledge and straightforward approach to the work made me comfortable trusting Voltlab and Evan with the project. About 9 days of work was spread over a month from first visit to last inspection and all went smoothly. Evan coordinated scheduling with city officials and inspectors and kept me informed at all times. His crew of electricians did a great job and respected me, my home and property. They are a talented and very experienced team. Evan is rightfully proud of the company he is building. Highly recommended."

Generator Install questions, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
