"Firefly Anything Tech overcharged me, delivered substandard work, and exploited a difficult situation for profit. I strongly advise others to stay away. On March 31, 2025, I paid Firefly Anything Tech $18,167.22 for a range of home improvement services. A key issue remains unresolved regarding $1,194 charged for labor and materials related to a cabinet door installation and drywall repair. The workmanship on both was unacceptable: the drywall repair was so poorly executed that I had to hire another contractor to fix it, and I personally had to redo the cabinet installation. Although Nathan was involved in the original job, he did not perform the cabinet or drywall work in question. Firefly?s only proposed solution has been to send Nathan back out, which does not address the quality concerns or reflect accountability for the work that was done. As a customer, I am refusing to have the same company return to correct work that was unsatisfactory in the first place."

Electrical repairs, installations (from ceiling fans to outlets) and more. Brush hogging, gravel driveway smoothing, small dirt moving projects. I have been an electrician for 21 years, and will take on small or large projects. I own some equipment I use for my own property, including tractor with front-end loader, post hole digger, bush hog, and more. If any projects needing done require this equipment, I can get someone out to quote. One thing that sets me apart is if you need a line run out to your building, I will also dig the trench.

"Was get my home renovated and needed a electrician.. Harris Did great work and great price and I was very satisfied.. DEFINITELY will call again."

Generator Install questions, answered by experts

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
