"Ben did a great job installing our bathroom exhaust fan. He was on time, very clean and charged me the price he quoted. He even wore protective booties over his shoes while inside the house. I'm now looking for more projects for Ben to do. Thank You again, see you soon Ben."

"Emanuel (and his daughter as helper!) did a great job installing a 240v EV charging station at my home last month. He was able to give me a bid after I sent him some pictures and rough measurements and when he came out to my home to do the installation, recommended a much better way to do the install (that no other electrician, even those who gave me bids after in-person visits, offered as an option). It's been working fine thus far.. I'd definitely recommend Emanuel. Thanks."

"Mr. Arechiga disconnected our old knob-an tube and grounded our 2 story home. We also had him upgrade our main panel to 200A solar ready. His responsiveness and professionalism made us feel safe and made this experience extremely easy. He was able to accommodate us within the week we highly recommend him!!"

"I contracted with Hector for two electrical projects. The first was for replacement of our 200 amp electrical panel. One problem I've had with contractors has been frustration at their lack of communication. Hector was always good at answering my calls, returning text messages, and keeping me informed. He did his work professionally for a reasonable price, so I hired him again to wire our shed. Again, he did the work professionally and kept me informed of his schedule. One area for improvement would be for him to pay more attention to what the customer says. Some work in our shed had been previously started with Romex installed through the studs. I told him this would need to be replaced with conduit per code. He again started installing Romex. He said he thought we would be installing sheet rock and it would cost more to change to conduit. But after I pointed out I had included flexible conduit in the written scope of work, he made the change with no additional cost or complaint."

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
