"Outstanding! Super professional. Offered advice on my electrical installation and did the work quickly. I was very pleased with the end installation."
"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."

"They were prompt, courteous, and informative. During the estimation process Darnell was very good and provided a very competitive price. I am pleased with the work done to install a new EV charger on the outside of our house"
"Ron Ethridge has been our Electrician of chose for the past three years. I started out using Ron to service my generator after the warranty lapsed. Heâ  s provided that big company expertise with that small organization connection. Since that time Ron and his team have provided electrical services for our entire home. I feel comfortable leaving Ron in our home while weâ  re away which is a huge feat for me particularly. Iâ  m grateful for the service that Ron and his team continues to provide to our family."
"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.
"Anthony is a true professional. He is very personable which made him easy to talk to. The young men working for him were courteous and about their business. Thought the prices were reasonable. Excellent service. If you are thinking about upgrading, installing outlets or any of your electrical needs, I highly recommend calling this company first."
"I ended up hiring someone else who could install a ceiling fan as Paradise Construction was afraid of needing to tear up a large section of the ceiling and I didn’t want to create additional work and expense."
While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.
Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.
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.
Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
