Service and Maintenance

Service and Maintenance for your Back-up Generator

If you have a backup generator, it needs to work 100% of the time because you don’t know when the power might fail. That’s why ongoing service and support is such an important part of what we do.

Our relationship with our customers doesn’t end after we install your back-up generator. We continue to take care of our customers through our comprehensive maintenance agreements.

At regular intervals, we’ll inspect and test your system, which will enable us to spot potential problems while they’re still small and ensure that when the lights go out, your backup generator will be ready to step in and fill the gap.

Residential or Commercial


The days of being prepared with extra flashlight batteries, candles and blankets for a possible power outage at your home can be a thing of the past with back-up power solution installed by PSI.

During power outages, you want to cover your bases with all the potential things that could go wrong. Like making sure that your basement doesn’t get flooded because the sump pump does not have power. You also want your tablets, phone and the internet available to you and to make sure that your family stays warm on freezing nights.

Increasingly more Washington, DC and Northern Virginia homes are being built with backup power sources and more homeowners are installing standby generators because losing power can cost your family personally and financially.

Today’s home backup power systems are affordable, compact, quiet, energy efficient, and most importantly, dependable. Systems today from Kohler and Generac can power an entire household while starting automatically after sensing a power outage.

Wide array of choices from Kohler and Generac for every home

Our Kohler and Generac trained technicians and home advisors can help you choose the power back up system that is right for your home. Should you choose to power your whole home or choose only specific circuits connected to vital in-home electrical components our tech team can help you make the correct choice.

Some systems have smart transfer technology that can free up capacity to also run non-essentials, such as a washing machine. Models range from 7,000 to 20,000 kW and are available in natural gas or propane.

Give us a call and we can setup a time for you to meet with one of our technicians who can walk you through and discuss options to ensure you always have power.

Whatever business you’re in, nothing happens without power. It’s something most people don’t think about very often because most of the time, the power that drives your business just works. You push a button and the computers power up. You flip a switch and the lights turn on. It’s what we expect.

Unfortunately, the unexpected is also a fact of life, and if you don’t have a plan in place to deal with an unexpected power loss, your business will be absolutely paralyzed every time there’s an outage and that costs you money.

We can help with that. As the region’s premier commercial electrical service provider, PSI has the expertise and services you need to ensure that your business continues to run, no matter what the world throws at you.

At the heart of any plan to keep the lights on in the event of a grid failure is a properly sized generator and we offer some of the best equipment you’ll find anywhere. Our award-winning Kohler and Generac generators range in size from 7,000 to 20,000 kW and are available in your choice of propane or natural gas. Whatever your needs are where backup power generation is concerned, we’ve got you covered.

In addition to that, we offer a comprehensive business automation service that allows you to monitor and control potentially every powered device your business relies on from an app on your phone.

Do you want to schedule the lights on and off at specific times and be able to override that as the need arises? Remotely turn equipment off when you get home if you left something on by mistake? Monitor your electrical usage and design routines that can save you serious money month to month? You’ll be able to do all of that, and more!
