"Duncan came to our house to qoute on t he electrical installation of 22KW back up generator. We were impressed with his knowledge of the scope of the job. The qoute was quite reasonable and complete. When we were trying to find someone to prepare the slab and sight, Duncan stepped up and expanded the scope of the work to include site preparation. Duncan took ownership of the project, coordinating with the gas line contractor and inspectors. Communication was good throughout. At the end, Duncan and crew, restored the site landscaping to its original form. We are happy to recommend Driven Electrical Solutions for your electrical projects."

"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 FAQs, answered by experts

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

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. 

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
