Home Standby Generators

Never Be Without Power

Power outages are becoming more frequent with weather, power line failures, and rolling brownouts. A brief power outage can be an inconvienence, but outages can quickly stretch from hours into days. Once bad weather hits, it's too late.

Get peace of mind and keep your family safe and comfortable.

Keep your food from spoiling, your air conditioning and heating system running, and your lights on - no matter how long the power is out.

Fully automatic, convenient uninterrupted performance.

An automatic standby generator is a backup power supply for your home. Conveniently connected to a permanent natural gas or liquid propane fuel source, you'll never have to worry about refueling the unit. Standby generators seamlessly integrate with your electrical system, automatically starting when it detects an utility power outage - whether you are at home or away. When power returns, the generator shuts off.

SRE will help you choose a system that meets your needs.

Proper sizing and installation of your generator is critical to ensuring that it is ready to operate when the power goes out. Whether your goal is to maintain key appliances and lighting, or to keep all the comforts of your home, such as central air conditioning, SRE will help you find the perfect system to fit your needs. Then we'll handle delivery, installation (including concrete pad for installation), and full electrical and gas interconnection. SRE offers generators from all major manufacturers, including Briggs & Stratton, Rheem, Ruud, Lennox, Kohler, and Generac.
