"My experience with Zero Electric was great! James was extremely knowledgeable about home generators and walked us through several pricing options that fit our budget. Their work was clean and efficient and I will definitely be hiring him in the future for our electrical issues."

"Very happy with the work completed by Bill (owner), Josh and Pat. Bill always responds promptly to text and calls and explains things clearly. Provided free quote and visited the house to confirm quote. Josh and Pat arrived on time and worked neatly. Josh was able to avoid trenching thru the ceiling even though attic space was limited. They even put back closet shelf that had to be removed to access attic. Josh and Pat even came by another day to help install a remote that I did not have on the day of installation."

"Very satisfied with upgrading a 100amp residential electrical panel to 200amp. Benjamin and his crew came out to review a 40+ year old panel and his bid laid out everything he thought needed to be done. His bid was similar/competitive with the other two I received, but as with anything like this, some extra costs did materialize after discussions with Edison and City of Long Beach; he explained all of these and got my sign off on everything he did/added, and at the end he kept the extra costs as low as possible. Benjamin’s communication was great and he tried to explain everything to me - the novice. During the “rough inspection” the inspector said “this is probably the cleanest and most organized residential panel project I’ve ever seen”. They also did a nice job of covering the old service mast and panel/meter box and cleaning up after the project. Orozco's will be coming back for some other work inside my house and I will probably eventually bring them back for some upgrades"

"The folks a M&ES CONSTRUCTION ENGINEERING INC. Did a great job with my project. They renovated my garage, they drywalled and painted it, also gave me a beautiful epoxy floor thats easy to clean and a treat for the eyes. I also had them remove my old brick gas fireplace and build a tile faced electric fireplace with an insert for my Television. My TV fits perfectly and it looks amazing. Workmanship is top notch, they are transparent, punctual, and very communicative. Truly the best contractors I’ve worked with."

Generator Install questions, answered by experts

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.

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.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

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

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.
