"I recently had the pleasure of working with Brian from Hamilton Electric for a hot tub installation, and I couldn’t be more impressed with the experience. From start to finish, Brian demonstrated the highest level of professionalism, expertise, and attention to detail. The entire installation was handled seamlessly, with meticulous planning and execution to ensure everything was up to code and functioning perfectly. Brian was incredibly knowledgeable, answering all my questions with clarity and confidence. His workmanship was outstanding, and he took the time to ensure a clean and safe setup. Beyond the exceptional quality of work, the pricing was very reasonable, offering great value for the level of service provided. It’s rare to find an electrician who combines technical expertise with such professionalism and customer-focused service. I highly recommend Hamilton Electric for any electrical work—especially for specialized projects like hot tub installations."

"In general, it went well. Everyone from Huft was very professional. The salesperson could not tell me the brand of water heater that would be installed. I had responded to ad on Angie's list. I should have paid attention to this. In the past, sales reps from other companies could tell me the brand name of the product, and if it qualified for a rebate. The product that was installed is an excellent product, but doesn't qualify for a rebate. The service personnel were all very polite and professional. What I would have done differently is pursued finding out the brand name of the product before it was installed and found out if it qualified for any SMUD rebates before making the purchase. In general, I would give Huft an excellent rating for service. They came back two days later when the water heater wasn't producing hot water, and installed new fuses. The technician was very professional and courteous. As a consumer, remember to jot down as many questions as possible before you meet with the contractor."

"Just had them come and install some can lighting in my hall way that I wanted for some time now. They were able to remove my old fixture in the hall and install 4 new LED can lights, even installed the dimmer I wanted with it. Much appreciated!"

"I have used the electric company for several jobs, and they have always been professional, efficient, and great to work with. From installing an exhaust fan to a whole new panel no job is too small or too big for them."

"The owner responded quickly and came to our home for a free estimate within hours. He recommended installing a new outlet to prevent electrical issues down the road. The job was completed within 72hrs (due to the weekend) and we were very happy with the work. I would highly recommend and will use them again for future needs."

Generator Install questions, answered by experts

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.
