"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"

"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."

"Really responsive and prompt, especially in the installation phase. We did have a couple of small hiccups, which in my mind a homeowner should expected on literally any remodeling project, and they were resolved quickly. Communication on final details like inspections could have been smoother, but overall the whole process was very clear, well managed, and well executed. Happy with the choice to go with Red Rocks."

Generator Install FAQs, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
