Why Homeowners Choose the Generac 7043

The Generac 7043 is one of the most popular residential standby generators because it delivers powerful, quiet, and dependable whole-home backup with minimal maintenance. Its 22 kW output provides enough capacity to run HVAC systems, refrigeration, lighting, and critical appliances at the same time — ensuring continuous comfort and safety during an outage.

This model’s G-Force™ industrial-grade engine is designed for long-life operation with pressure lubrication and faster response under load.

    My wife and I love our new Generac 22kW generator. It arrived quickly and undamaged. Our electrician had no issues with the set up. Only mistake that we made was that we did not tell the electrician what time to have the generator run through its weekly cycle. It was set at 1:00am. We heard it come on because the generator is located outside our window. Not a big deal as we could easily change the weekly cycle time so we set if for Saturday afternoon. Great product.
