"I had a fantastic experience with Voltsmith Electric. After hitting some confusion with a charger installation from another company, Mike came out, knew exactly what he was doing, and got our Level 2 EV charger installed and running at full power with no hassle. He was prompt, professional, meticulous with his work, and cleaned up everything before leaving. A completely smooth process from start to finish."

"I recently had a light fixture installed in my office and an electrical outlet relocated to a different area, and I couldn’t be happier with the results. The electrician was professional, punctual, and paid close attention to every detail. The installation was clean, the work was completed efficiently, and everything looks and functions perfectly. It’s clear they take pride in their craftsmanship and customer service. I highly recommend them to anyone looking for quality electrical work. Thank you for doing such an amazing job!"

Generator Install FAQs, answered by experts

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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.

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.

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.

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.
