We are your 1-Stop Source for your Standby Generator Needs! Factory Authorized Cummins Power Generation, Generac and Briggs & Stratton Dealers for Sales, Installation & Service SciFiHomes, Inc. was founded to provide the Shenandoah Valley and Surrounding Areas with a Hi-Tech Electrical Contractor that is a 1-stop solution for the Homeowner and Small Business Owner (from Standby Generators to Security Systems to Home Theaters and most everything in between). SciFiHomes is committed to providing the best electrical/electronic products and solutions available, competitive pricing, our signature high-quality and high-performance installation, and unmatched technical support. SciFiHomes's mission is to offer the most comprehensive personal attention to your Personal, Family, and Business electrical/electronic needs or desires.

"These guys did a fantastic job and were an absolute pleasure to work with. Small business, all primary work done by the three owners/operators of the group, who are are masters in their respective fields: "Tech Guy", Electrician, and Gas Fitter. (I genuinely hope to not cause offense by this broadly generalized description). I had a 20kW Cummins LP/NG-fired automatic backup generator installed and connected to a new automatic transfer switch, and (since we had no existing gas system) a new 500gallon LP propane tank installed and under-grounded to feed the generator. My main electrical panel was brought up to current code in the process. The excavation and burial work was subcontracted to a trusted local operator that did really nice work, and they worked with Southern States to provide a tank and first fill. They handled all the permits and coordinated the inspections. Waiting for the county inspector, and waiting for Southern States to fill the tank after the gas inspection, were the only observable delays in the process, and those were negligible/reasonable. The SciFiHomes people were quick, efficient, and obviously practiced with all of their pieces of the work. They will strongly prefer Cummins-brand generators over the competitors, and they are more a more expensive initial investment compared to them. After doing my own research after their sales pitch, it is a very worthwhile "upgrade". The difference between Cummins' generators and the competitors is fuel efficiency; according to the math, I'll get over 24 hours of additional runtime vs (as an example) Generac's 20kW generator at 40% average load on a full 420gallons of propane in the new 500gal tank. With an extended outage, or multiple long outages as with last winter in Frederick County, that's a very significant advantage. Sorry for the "sales pitch"; I only included this to prove that they're in my opinion very justified in pushing the "premium" brand. We purchased the extended warranty uplift as well as their extended service agreement. We can't recommend them enough; fantastic experience, and this generator has already flawlessly provided over 20 hours of outage coverage in the 5 months we've had it. Winter is coming, and we'll be ready this time. It just works... These guys and their total solution probably isn't the absolute cheapest in the area... but we absolutely got what we paid for. Thanks SFH!"

Generator Install questions, answered by experts

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator.
