When storms, grid failures, or utility outages strike, nothing is more frustrating than losing heat, food, Wi-Fi, or security systems. Ehret now offers Generac generator sales, installations, and repair services—bringing you peace of mind in every outage.

Why Choose a Generac + Ehret

Generac is one of the most recognized names in whole-home standby generators. Its systems are designed to provide dependable backup power, helping homeowners keep essential appliances and systems running during an outage.

 

Generac standby generators continuously monitor your home’s electrical service. When an outage is detected, the generator starts automatically—often within seconds—and transfers power to your home without requiring manual startup, even when you are away.

 

Generac generators are available in models that operate on natural gas, liquid propane, or diesel fuel. Ehret can help determine which fuel source and generator configuration best fit your property, available utilities, and backup-power needs.

 

Many Generac models include Wi-Fi connectivity and remote monitoring capabilities. Depending on the system, you can use a compatible app to check generator status, receive maintenance reminders, and be alerted when the generator needs attention.

Ehret’s licensed technicians will evaluate your home’s power requirements, recommend the proper generator size, and complete the installation carefully. We also integrate the transfer switch and related components so the system can operate safely and reliably during an outage.

 

Ehret provides continued support after your generator is installed. Our local team can assist with routine maintenance, repairs, warranty-related service, and system questions to help keep your generator ready when you need it most.

GENERAC FAQ'S

Yes. A Generac standby generator continuously monitors the electrical service to your home. When it detects an outage, the system starts automatically and uses a transfer switch to begin supplying backup power—usually within seconds. When utility power returns, the generator switches your home back to the electrical grid and shuts itself down.

 

Generac standby generators commonly operate on natural gas or liquid propane, allowing many homeowners to use an existing fuel supply. Diesel models may also be available for larger residential or commercial power demands. Ehret can evaluate your property and recommend the fuel source and generator that best fit your needs.

Most installations require approximately one to three days of on-site work. The exact schedule depends on the generator’s size, installation location, electrical and fuel connections, site preparation, permits, and inspections. Ehret will evaluate these requirements and explain the expected process before installation begins.
