We are a woman and family owned company based out of Castle Rock, WA. My husband and I are both electricians with a combined 15 years experience. We strive to provide quality workmanship and excellent customer service to ensure you and your home are well taken care of. We look forward to working with you on your next project!

"This was a new $800,000.00 home We still don't have the house signed off from Cowlitz county planning because of Fusion Electrical Services LLC have not completed it BUT WERE PAID IN FULL OVER A YEAR AGO.My mini split has not been completed in 13 months, my breaker panel hasn't been put back together in a year, I paid parker and alissa in full.The owner Alissa tried to put a protective order against me back in August because I sent her text message asking when will they complete my job. I sent her a correction notice from Cowlitz county planning showing her all the correction needed. The Judge said me texting to get my job done was NOT harrassment. Since then I found out from Feltons HVAC good guys, that the electrical wires that Fusion spliced Diakin says no you can't, that is why my mini split won't work. They cut my new cooling lines I supplied in the kit, they said they had to because the lines were to short. That is not true it's because Parker had no clue what he was doing and didn't install the inside unit first then measure the lines and wires then set the height of the outside unit. We are forced to go back to court in a few months. They received 3 separate violation from WASHINGTON STATE LNI on my new home, now LNI just notified us about some other things. Parker and his company are not licensed to do HVAC work, he said he was licensed and bonded for HVAC he lied, FYI you cant file a lien on thier bond for HVAC even though they did the work and destroyed my install kit for my mini splite, I have a invoices from another company to fix the mess, replace the destroyed kit and complete the job on the mini split for over $5000.00 and for electrical over $5000.00 She won't resolve it I have tons of text messages asking her to just get it completed, she tells me she will jerry rigge it with no new parts, I paid for new I want the job done correctly .

With several years experience, we work hard to bring each customer the best possible service and quality available. We look forward to working with you on your next project. We welcome your questions and thank you for your interest.

"We needed to upgrade the electrical in our mobile home and add power to our garage/shop. I called ASE and spoke to Art. He was able to come out that day and give a bid. Also met me at my son's house later that day to check out an electrical issue. Bids were very acceptable and work was scheduled. Work at my son's was done a couple days later. I requested a later date due to prep work and 2 electricians arrived right on time. I had all new receptacles installed, ran 3 new circuits (AC, extra hot water tank and split a previous circuit), wiring ran for new ceiling lights, rerouting old wiring and neatening wires from a wall removal. Our little garage/shop had only 1 available receptacle for everything (freezer, lights, etc). Now we have 16 receptacles for 110 and a drop cord for 220. We are so happy! Equipment that has been sitting for years can now be used and no more blowing a breaker if too many amps are used. In the house I can plug in the vacuum without having to crawl under the table or move something to get to a receptacle. Art, Jerron and Hayden were great to work with. They all listened to us, made suggestions and accomplished everything we needed. Highly recommend!!!!!"

"Jeremy just can't keep promises. Nothing is done when he says it will be, sloppy work with zero cleanup, poor to no communication. After discovering a switched outlet his guys installed didn't work, I asked him to fix it. Three different times he promised to do so and no-showed. Finally after several months of this he simply stopped responding. Cost me $630 to have Shocking Difference fix the shoddy work but at least they did it right. Don't be like me, check this guy out at https://secure.lni.wa.gov/verify/ before hiring him for anything. You can see any contractor's violations there. I wish I had checked first."

Generator installations FAQs

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

  • Portable generators with 1kW–7.5kW capacity: $500–$2,000

  • Partial generators with 9kW–20kW capacity: $2,000–$6,300

  • Whole-house generators with 22kW–48kW: $5,000–$18,000

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

  • Experience frequent or prolonged power outages

  • Work from home

  • Store a lot of cold food

  • Have a sump pump

  • Have a pump for well water

  • Use electronic medical devices

  • Live in a climate requiring heating or cooling
