"Sergio and his assistant installed an EV charger at my place, and they did an amazing job. I’m so glad I hired them. Their price was reasonable compared to other contractors. I highly recommend them and would definitely use their company again for any future jobs."

"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"

"This was an usual project. It was redoing a mini bar. Hard to find a contractor that would do it or had the time. Homepro was great lead by project manager Shir Hadad. Jumped right in there and took it on and got the job done. Really appreciate their professionalism."

Generator Install questions, answered by experts

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.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

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

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

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

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.
