How it Works

  • Food spoilage & freezer losses

  • No heating or cooling during a winter/summer outage

  • Security systems, cameras, and smart home systems go dark

  • Medical Equipment stops running

  • Water pumps, sump pumps, and well systems fail

  • Loss of comfort, safety and peace of mind

Generator sales & Installation

  • We offer full Generac product lines and handle the complete install—from foundation pad to wiring and transfer switch. We size your generator to cover essentials (HVAC, fridge, security, sump pump) or even whole-house loads depending on your needs. Our installations meet local code, pass inspection, and are done right.  

generator repairs & Maintenance

  • Not only do we install, we service too. Whether it’s routine maintenance, battery replacement, fuel system cleanup, or repairing components (starter, alternator, sensors), our techs keep your unit ready to protect your home.  

generator upgrade & Expansion

  • Already own a generator? We can upgrade its capacity, add circuits, or convert fuel types. If your system isn’t covering what you need anymore, Ehret can help expand or replace it to bring full coverage.  

remote monitoring & smart controls

  • Many Generac models include WiFi or cellular monitoring, so you get alerts and system status on your phone or dashboard. Ehret can configure these systems and monitor alerts to stay ahead of issues.
