"Target Electric Enterprises Inc replaced and upgraded my 50 year old main electric panel and I’m so glad I selected them for the job! Sean was responsive from day 1 and kept me fully informed throughout the process. My job required installing a new underground cable also, which involved several interactions with SDGE and City of San Diego, and Sean and Steve very capably handled every step with skill and efficiency. In the field, Steve has extensive expertise and obviously takes great pride in getting the job done right. Their pricing was also very reasonable, and I totally recommend them for any electric job, small or large!"

"Marvin provided a detailed estimate that my condo homeowners association board could easily approve. He was extra thorough and flexible in making the electrical changes in my laundry room needed for my new washer and dryer. He ensured that everything was completed to my satisfaction and followed up afterwards too! I would definitely hire Marvin again for additional work in my home."

"I contacted Fregoso Electric Service through Homeadvisor for a ceiling fan installation. Their quote was a good price. They arrived on time and installed the ceiling fan and I also had them replace two outlets in the dinning room. Great service. Great price. I highly recommend. I will use them again."

"I had Mister Sparky come out to install a ceiling fan at my house and the experience was great from start to finish. The technician was professional, showed up on time, and got everything installed quickly and cleanly. You can tell they take pride in their work and pay attention to the details. If you’re looking for a reliable electrical company that does quality work, I’d definitely recommend Mister Sparky."

"Keith Walter the owner, was very professional and easy to work with. We worked out a proposal that was within my budget without sacrificing the scope of work necessary to get my home completely rewired. His workers were conscientious, hardworking and rewired my old 1942 home with minimal cutting into my plaster walls. I plan to do some additional wiring and lighting for my yard and backyard deck and I will most definitely go with Walter Electric."

Generator Install questions, answered by experts

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.
