"Having owned four different houses the past 16 years, this was hands down the best experience with a plumber... ever. We hired WyattWorks to install a laundry sink (the stainless over cabinet kind) which required drilling through the floor to tie-in with supply and drain pipes in our basement. Jeremy performed the work flawlessly and was a true pro: measure and recheck, plan and dry fit, and clean up the work area during and after. The whole process from start to finish was painless!"

Generator Install questions, answered by experts

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
