"After my request for an electrician on Angi.com, I immediately received a call from Duncan who set up an appointment to give us an estimate. We agreed on the cost, and Duncan set up an appointment for the following morning. Master electrician Elaina arrived promptly at the agreed upon time and completed the rather challenging job in record time. Price, communication, and professionalism exceeded my expectations."

"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."

"☆☆☆☆☆ dream team COMPANY! I had most contact with Julian throughout the job, but his partner and Electrician were JUST AS NICE. They had cloths on my floors, as they were in and out of my crawl space. They even left to get a particular component, specific for my install. No damage to home. There was no laughing or joking around. They were concentrated on install, measuring, calculating out loud between the three of them. No cussing or profanity, either. Julian was professional and explained everything to me, including why manual was left on unit, so when inspector came, it was there, as it couldn't be signed off without it. Thermostat looks great! He also knew a lot about furnaces, which is my next thing. *Beware of companies won't give you prices on ANYTHING and/or charge you estimate to come to your house... Another reason I picked PEAK HOME was their receptionists! Sweetest, most understanding ladies! If you need to install A/C, go with this company - definitely recommend!"

"Bradley is very professional and very knowledgeable and on time. He was also able to get started on our house right away when others said it would be weeks. Our breaker box was very old and the wiring in our house was a mess and it needed replaced and repaired. We only had a couple of electrical outlets inside the house and we had no power to the bathroom. We also wanted him to also install new ceiling lights and we wanted him to add new outlets. Bradley replaced the old fuse box with a new fuse box and he added new outlets and replaced the old ceiling lights with new ones. He also got power restored to the bathroom. When he was done everything worked like brand-new and his rates were by far the best that we could find. It was the first time ever using an electrician that we felt like we didn't get ripped off."

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator.
