Whole-home generator costs vary based on generator size, fuel source, transfer switch type, electrical panel configuration, gas or propane line requirements, permits, trenching, and installation complexity. As a general range, smaller standby generator installations may cost around $10,000–$12,000, common whole-home systems may range from about $13,000–$18,000, and larger systems may cost $15,000–$22,000 or more.
The right generator size depends on what you want to power during an outage. Essential-circuit systems may cover heating, refrigeration, lights, and a few outlets, while larger whole-home systems can support more appliances and comfort equipment. A licensed electrician should perform a load calculation to size the generator properly for your home.
In many cases, a standard portable generator is not the best option for powering a heat pump. Heat pumps can require significant startup power, and modern inverter-driven systems may be sensitive to power quality. For reliable backup power for a heat pump, a properly sized standby generator with a transfer switch is usually the safer and more dependable solution.
A portable generator is a temporary unit that must be moved, fueled, started manually, and connected safely during an outage. A standby generator is permanently installed outside the home and connected to your electrical system through a transfer switch. Standby generators can turn on automatically when utility power goes out and provide a more convenient whole-home backup power solution.
An automatic transfer switch safely disconnects your home from utility power and connects it to generator power during an outage. When utility power returns, it switches the home back to the grid and shuts the generator down. This prevents dangerous backfeeding and allows a standby generator to operate automatically.
Backfeeding happens when a generator is connected to a home’s wiring without a proper transfer switch. This can send electricity back into utility lines, creating a serious electrocution risk for utility workers and neighbors. It can also damage your generator, appliances, and electrical system. A transfer switch is the safe, code-compliant way to connect generator power to a home.
Most whole-home standby generators run on natural gas or propane. Natural gas is convenient when available because it does not require refueling during an outage. Propane can be a good option for homes without natural gas service. The right fuel source depends on your home, available utilities, generator size, and installation location.
Yes, a properly sized standby generator can power most or all of your home during an outage. The exact coverage depends on generator size and your home’s electrical loads. Some homeowners choose essential-circuit backup, while others choose a larger generator designed for whole-home coverage, including heating, cooling, refrigeration, lighting, outlets, and key appliances.
Yes, but the generator must be sized correctly for the equipment. Furnaces generally require less electrical power than heat pumps or central air conditioners, while heat pumps and AC systems may have higher startup loads. A load calculation helps determine whether the generator can safely run your heating and cooling equipment during an outage.
A whole-home generator is typically installed outside the home on a concrete or composite pad. The location must meet clearance requirements from windows, doors, vents, property lines, and fuel connections. Your installer will help choose a location that is safe, code-compliant, accessible for maintenance, and practical for electrical and fuel connections.
Yes. Whole-home generator installation usually requires electrical permits and may also require mechanical or gas piping permits depending on the project. Permits help ensure the generator, transfer switch, wiring, fuel connections, and placement meet code and safety requirements. A licensed contractor can handle the permitting process for you.
The active installation for a whole-home generator may take a few days, but the full project timeline can vary based on equipment availability, permitting, inspections, utility coordination, gas or propane work, trenching, and site preparation. Your installer should provide a project timeline after reviewing your home and backup power needs.
A standby generator should be professionally serviced at least once a year, or according to the manufacturer’s maintenance schedule. Maintenance may include checking oil, filters, battery condition, electrical connections, transfer switch operation, fuel connections, and test-running the system to make sure it is ready before the next outage.
