Generac Generator Sales, Services, & Maintenance

We’re all aware of catastrophic storms that can knock out power to millions. But, while hurricanes and tornadoes grab the headlines, the fact remains that nearly 70% of all weather-related power outages are caused by thunderstorms that can occur almost anywhere.

As a leader in whole house generators, our top-of-the-line Generac generators, along with our skilled technicians and electricians, effectively ensure that you’re never left in the dark.

When it comes to giving your family the ultimate peace of mind, turn to the experts at Green HVAC Services. We are at Ashburn, Great falls, Loudoun, Fairfax, Arlington, Alexandria, Prince William, Fredericksburg, Stafford, MD, and DC with high-quality generators, repairs, and maintenance services. Our trained technicians also provide full installation services of your backup generator, so all you must do is turn the key!

How long can you run a Generac whole house generator?

While Generac generators can run longer than 24 hours during power outages if needed, it’s still a good idea to check on your Generac every day to make sure it’s running properly. Generac recommends that you schedule professional maintenance on your backup generator every six months.

Will a 22kW Generac generator run your whole house?

For homeowners wanting the ultimate entry-level whole-house standby, a 22kW is a perfect choice to reap all the benefits of a whole-house generator over a regular home standby. A generator in the 27-36kW range is perfect for most homes since they replace 75% of the 200 amps coming into your electrical panel.
