When some homeowners think of a generator, they think of a portable model that can be moved around. They are much smaller than a home generator and can only provide enough electricity for a couple appliances at a time.

A standby generator is hardwired into your home’s electrical panel and turns on automatically in the event of an outage. Not only is this safer during stormy weather, but it also allows this type of generator to power your lighting, HVAC system and more.

If you’re using a portable model, you’ll need to follow a long list of generator safety procedures, since they produce carbon monoxide. A whole-house generator is permanently and safely installed outside your home, giving you peace of mind.

A-1 United is proud to offer Generac generator installation in Omaha, NE, and surrounding areas. As the leading brand of home backup generators, Generac is preferred by 8 out of every 10 homeowners who invest in standby power for their home.

Great job by all. They were careful of the landscape replacing the A/C unit. Inside the heating system was replaced and the fit and finish was great. Explained the operation of everything. They came back two weeks later and checked out the operation of the systems plus installation. The tech was here over an hour checking out everything. New system is quiet. This is a company that care about its customer. We highly recommend A-1.
