Standby and portable generator installation and service..
Whole-home standby generators automatically provide backup power during outages, protecting against food spoilage, frozen pipes, sump pump failure, and loss of medical equipment. Natural gas or propane-fueled standby generators (typically 12–24 kW for residential use) start within seconds of a power outage via an automatic transfer switch. Installation involves an electrical subpanel or whole-house transfer switch, a concrete pad, gas line connection, and compliance with setback and noise ordinances. Portable generators serve as a lower-cost option for partial backup but require manual setup and fuel management.
What to look for when hiring a generators contractor
- ✓Ask the installer to perform a load calculation to properly size the generator for your home.
- ✓Confirm the estimate includes the transfer switch, concrete pad, gas line, and all permits.
- ✓Ask about warranty terms — most major brands offer 5-year limited warranties.
- ✓Verify the installer is authorized by the generator manufacturer (Generac, Kohler, Briggs & Stratton).

What size generator do I need for my home?
Sizing depends on what you want to power during an outage. A 12–14 kW generator handles essentials: refrigerator, sump pump, furnace, lights, and a few outlets. A 16–20 kW generator adds central air conditioning and a well pump. A 22–24 kW generator can power an entire average home including an electric range and dryer. Your installer should perform a load calculation based on your electrical panel to recommend the correct size. Oversizing wastes fuel and money; undersizing causes the generator to overload and shut down when you need it most.
How much does a whole-house generator cost?
A whole-house standby generator costs $5,000–$18,000 installed depending on size and fuel type. A 12 kW air-cooled unit runs $5,000–$8,000 installed. A 22 kW unit runs $8,000–$15,000 installed. Larger liquid-cooled units (25+ kW) cost $12,000–$20,000+. Installation includes the generator, automatic transfer switch, concrete pad, gas line connection, and permits. Natural gas is the most convenient fuel (no tank to refill); propane requires a tank ($1,000–$3,000 for a 500-gallon buried tank). Annual maintenance costs $150–$300.
