"Raul is awesome! Couldn't have asked for a better electrician to work on my projects. He is an expert and has a great work ethic. He installed a chandelier, light switch, and neon sign above my fireplace. He also rerouted wires in my guest bathroom and installed a vanity light. He also added three outlets in the house. Great work all around. I would definitely recommend him for anyone that needs electric work done."

"Electrical work may be on the expensive side but totally worth it!!! Giovanni put a new panel in for us and Kegan installed outdoor lighting where there wasn't any previously. Both were polite, knowledgeable, professional & personable. I am extremely satisfied with their hard work! I would & do highly recommend Mr. Sparky for all of your electrical needs."

"Seamus Donohue was a man who knew his subject - lightning. He came to our home quickly, and scheduled installation immediately after we made a decision. The men who came to do the installation were professional, careful and took time to make sure the results were as "invisible" as possible. We hope never to have a lightning strike again at our home, but as the weather patterns change, we fear that is more possible than in the past. We feel more protected after our lightning protection installation. But you never know how successful something is if the proof is in something never happening! But we'll take it."

Customers say: Quick response
"Great work and exactly what I had in mind. I have an old 1950â s house with a few choppy looking outlets/wiring in the garage. Completely gutted the garage and wanted to add more outlets and light fixtures, and overall upgrade the area. Todd came in and his work exceeded my expectations. The space is now brighter with added lights and more convenient with the extra outlets. Great job. I will be calling him in the future for my other projects on the list."

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
