"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!"

"You cannot find a better contractor than Raufi Services. We hired Raufi Services to install 240V/50A wiring for a hot tub. They were extremely efficient, polite, and timely. The quality of their work was outstanding--I couldn't even tell they ran the wiring in the house after they were done. They were also very competitive in their cost estimate."

"Malone Electrical was competent and professional. Pricing was overall fair but nowhere near cheap. We hired him to install an upgrade to our electrical service from 80amps to 200amps and that's what we got, in a reasonable amount of time. He wasnt overly friendly though and would not baby the customer in any way. I would hire him again."

Generator Install FAQs, answered by experts

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
