"I chose Elevation Electric to install an outlet in our garage for our new Nissan Leaf because he was the ONLY installer recommended on both the Xcel Energy site and here. I heartily agree. Our new outlet is in a great spot and works perfectly. Joe worked quickly, had to drill through brick walls and cleaned up the mess. He was forced to cancel our initial appointment due to complications on the job before ours. So what did he do? He rescheduled for a Saturday because he hated to have inconvenienced us with the cancellation and he was already booked for the next week. Nice guy, good work!"

"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."

"Todd Chaney is an exceptional electrician. He has completed work for me on a mechanic shop, a vacation rental, and a mixed‑use retail building, and the quality has been consistently excellent. Todd understands the full construction process, which makes him highly effective at diagnosing issues and installing or repairing electrical systems in any situation — residential, commercial, or older structures. I’m hiring Todd, with Pink Brick Electric again this spring to handle major electrical work on my 1880 Queen Anne Victorian. Projects like this require experience, precision, and good judgment, and I trust Todd completely. He communicates clearly, gives honest and thoughtful feedback, asks the right questions, and respects the homeowner’s perspective. Working with him is straightforward and professional. The Pink Brick is a company built on integrity, and I recommend them without hesitation"

"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"

"Plumber Clay is AWESOME, as the company name indicates. Clay went above and beyond to explain everything that caused my emergency leak/s, he identified the source of my ongoing plumbing emergencies that the previous plumbers couldn't figure out--AND THAT PREVIOUS OWNER DIDN'T DISCLOSE--nor did 3 inspectors to buying this house. He scheduled repairs to work with my budget constraints to hopefully resolve ALL issues. Clay is experienced and well informed, shared his observations, made sure that he answered all of my questions and concerns, and even got me scheduled for additional Awesome Home Services, as they offer more than just plumbing and heating!!!"

"Shawn and his team were awesome for this project. They understood immediately what realistic budget was, provided very clear itemized project updates as things went on, took care of all the work, and worked with me to complete it all in two days while working around my busy corporate lifestyle. Work was done very clean, conscious of keeping costs low but with quality, and they were fast and friendly. Highly recommend going with them over any of the big 3 companies who will quote you way too much, provide no itemized receipt or options."

Generator Install questions, answered by experts

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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.

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
