"Installed a 12 circuit generator cutover panel. Works great. Would have preferred the cables to be behind the drywall. But a solid job that passed Jeffco and Xcel inspections easily."

"Tom was great at installing my RV outlet. Out of the 3 different quotes I received, he was able to get it done without trying to talk me into more expensive options. He was also accommodating with my somewhat busy schedule and very responsive throughout the install planning process. I would highly recommend Productive Electric."

"Absolute Electrical did a great job of installing our QuietCool fan. They were very professional, thoughtful (quietly closed front door as they went in and out) and cleanly (thoroughly cleaned work area). I would recommend them to any of our neighbors and friends."

"Back in 2024, Jesus and his team did a phenomenal job adding a new circuit/outlet in our garage for our new chest freezer and outlets with USBs for our e-bikes and other gear. He came in the morning to talk about the project and give and estimate and they were able to complete the work same day even though it was a bigger project than I’d originally described in my request. He explained the options well and was able to put everything exactly as we wanted. Very happy with how that project turned out. This year, we hired Jesus’s team again to install new light fixtures in our bathroom (vanity lights and sconces) and move some outlets. Again he and his team did a great job and were lovely to work with. We’ll be reaching out for more assistance with our bathroom reno."

"I’m extremely pleased with the work Jon from TORQ Electricians recently completed in my home. This project was much larger than his visit the week before, and once again he delivered outstanding results. He replaced switches and outlets throughout the house, many of which had begun to fail due to age, and the upgrades have given us real peace of mind when it comes to safety. Jon also made several thoughtful recommendations—installing dimmer switches in the kitchen and study, and suggesting a different dimmer style for our living room ceiling fan. These changes have noticeably improved both the functionality and the atmosphere of those rooms. He even identified and replaced a GFCI breaker in the panel that wasn’t up to code, ensuring everything is now safe and compliant. The work has refreshed the look of our interior, and we couldn’t be happier with the results. We’re very glad we chose TORQ Electricians and highly recommend Jon to anyone needing professional, reliable electrical work"

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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. 

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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.
