"Outstanding service. I originally needed an electrician to determine why I lost power to ½ my house. What Jody uncovered was a defective circuit breaker and my main switches overheating and in the process of melting down. He was able to change out the panel and install new breakers immediately. I’m grateful for the prompt response by Gene and the professionalism of Jody and Brian."

"We had been considering a home generator for a few years as the power grid we are on has periodic problems, with no solution in sight from Dominion Power.  We did our due diligance on interviewing a number of providers found on Angies List.  In the end, we had a couple of good offers, but none we are responsive as Patrick Collins of Ritzau. LLC.  Patricks team we very responsive and professional.  From the time I asked to schedule for an estimate until the deal was complete...he was always matter of fact and to the point, timely with responses to my questions, and was always open and honest.  His company is smaller than some I interviewed, and he actaully is the installer and has hands on the entire project.  Others companies while competitive, had sales reps visit and do the estimates, and were not part of the install team.  It has been my experience that you want to deal directly with the team lead for these types of projects, and Patrick was the best.  The package deal included the lastest Generac 22KW generator, vice the 20KW that others offered.  The long pole in the tent was getting Washington Gas to install upgraded gas meter that would accomodate the generator, and the Fairfax Country inspections.  
Overall this was an excellent experience.  I would highly recommend Ritzau, LLC and Patrick Collins to anyone who is serious about getting a home generator.  They are the pros and get down to business.  Quick, professional and timely.

"We would definitely contact Mr. Williams for more household projects. He installed a gas cooktop with a downdraft for us. During the install, he discovered that the vent pipe being used by the old downdraft fan was too small. To ensure that we would have a working cooktop that evening, Mr. Williams went to the hardware store for new parts. The price of the project was very reasonable. He also followed COVID-19 safety protocols (mask, gloves, social distancing, staying within the worksite) for the entire project."

Generator Install questions, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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. 

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home
