Generator Install questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
