"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!"

"We had a couple of companies give us estimates for replacing our HVAC system. Snell was not the least expensive but after researching systems and costs, I was able to determine that the Lennox system was superior to what the other companies were offering. The installation was completed on one of the coldest days of the year. The install crew was great. They were careful, respectful, efficient, and their workmanship was very professional. They took the time to review the installation components and what our expectations should be with the system. They went over the digital thermostat settings and how to adjust them. They were quick to respond to a concern we had with the humidifier. They completed the work in the time frame we were given."

Generator Install questions, answered by experts

For generator upkeep in Fairfax, keep a socket wrench set, multimeter, spark plug wrench, and shop vacuum available. Stock synthetic 5W-30 oil, spare air and oil filters, spark plugs, and fuel stabilizer. Cleaning supplies like degreaser, a wire brush, and compressed air are useful, along with weatherproof tape, a battery maintainer, ice melt for winter, and a tarp to shield your backup power unit seasonally.

Helpful?

In Fairfax, homeowners should factor in local noise restrictions, typical lot sizes, and the prevalence of mature trees that may limit generator placement. The area’s clay-heavy soil can affect foundation stability, especially during wet seasons. Dense underground utilities require careful planning before digging. Additionally, check if your neighborhood’s HOA has specific rules for backup power systems or visible home standby generator installations.

Helpful?

To enhance safety for families in Fairfax, use lockable enclosures or decorative fencing to restrict access to your generator. Place the unit away from common play areas and bedrooms, and use landscaping to reduce noise. Install childproof latches, clear warning signs, and shield hot surfaces to protect pets. Teach everyone emergency protocols and install carbon monoxide detectors to make your home standby generator setup safer.

Helpful?

After installing a generator in Fairfax, arrange for a final inspection to confirm code compliance and ensure your backup power system is properly integrated. Register your equipment for warranty protection and document the installation with photos for insurance purposes. Test the transfer switch, set up routine exercise cycles, and review emergency procedures with your household. Update your insurance policy to reflect the new home standby generator.

Helpful?

In Fairfax, generator longevity depends on correct sizing for your home’s power needs, a stable foundation suited to local clay soil, and weather-resistant enclosures to handle VA’s seasonal storms. Regular professional maintenance, weekly test runs, and prompt attention to minor issues help ensure reliability. Choosing reputable local installers and keeping detailed service records will further protect your backup power investment over time.
