"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!"

"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."

Generator Install questions, answered by experts

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.
