"I have been hiring Cody Malone since we purchased our house in July 2012. They have switched out outlets, installed indoor ceiling fans, installed outdoor ceiling fans, ran electrical to my outdoor water feature and switched out my light fixtures. I plan to hire them again when I add electric to my detached garage. They always do a great job and arrive when they say they will. I have never had a single issue and they have been to my house for no less than six different projects!"

"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!"

"I had an excellent experience with Kevin. He installed a very large and complex crystal chandelier in our foyer, and the entire process was handled with exceptional professionalism and precision. This was not a simple installation,the chandelier is heavy, intricate, and required careful assembly and mounting at a significant height,but he approached the job with patience, attention to detail, and clear expertise. He took the time to ensure every component was perfectly aligned and secure, and the final result looks absolutely stunning. The installation was done safely, efficiently, and with great care for our home. I would highly recommend him to anyone needing electrical work, especially for challenging or high-end lighting installations. Truly outstanding workmanship."

Generator Install questions, answered by experts

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
