Power for your whole home, automatically
A whole-home backup generator does exactly what it sounds like: when the power fails, it powers your entire home — not just a few circuits. Heat in the winter, AC in the summer, refrigeration, sump pumps, medical equipment, internet, and everyday comfort all keep running, automatically, until the grid comes back.
Power Up designs and installs whole-home backup systems sized to run your house with room to spare. The generator senses the outage, starts on its own, and transfers your home to backup power in seconds — then switches back when utility power returns. It's the highest level of peace of mind a backup system can offer.

What's the difference between whole-home and essential-circuit backup?+
Essential-circuit backup powers a selected set of circuits — typically heat, fridge, and a few outlets. Whole-home backup powers your entire house, including air conditioning and large appliances. Whole-home offers the most seamless experience; we'll help you decide which fits your needs and budget.
Will a whole-home generator run my air conditioning?+
Yes, when sized correctly. A properly sized whole-home system is designed to handle large loads like central AC and heat pumps. We calculate your home's full demand so the generator can run everything you expect it to.
How quickly does it kick in during an outage?+
An automatic whole-home generator detects the outage and restores power within seconds — fast enough that you'll barely notice the interruption. When the grid returns, it switches back and shuts down on its own.
What fuel does a whole-home generator use?+
Most run on natural gas or propane. We'll help you choose based on what's available at your property and handle the fuel connection as part of the installation.
Does a whole-home system need maintenance?+
Yes. Like any standby generator, a whole-home unit needs regular maintenance and periodic load testing to stay reliable. We offer service plans and monitoring to keep your system ready year-round.
