Welcome to our profile. Integrated Electrical Solutions is a full service electrical house. We do great work, at a fair price. Our pricing is very simple: we charge a $175 service fee, and $150 per hour for Lead Electricians, $115 per hour for Second Electricians, and $85 to $95 per hour for Helpers. , plus parts for electrical, drain work and appliances. We service all brands of portable and stand by generators. Work before 6 am as well as night after 6pm, weekends and holidays is subject to additional charges. We normally charge $125 to clean dryer vents and that's it. We provide outstanding, well equipped mechanics, who know their jobs. YOU GET WHAT YOU PAY FOR- TOP SHELF FIVE START SERVICE. Integrated Electrical Solutions is a fully licensed and fully insured electrical company. We do emergency work 24/7, 365. When you want the best and you want it done right the first time, call us. thank you!

"The experience was not quite what I expected. I had clearly explained the scope—replacing 10-12 standard switches with smart switches giving model number/spec—and was hoping for a lump sum proposal, but they only offered hourly rates, which is understandable. They estimated it would take about 2 hours, but the job ended up taking over 4. While they mentioned having done similar installations before, they spent quite a bit of time reviewing instructions on site, which added to the time and cost. The final bill was over $800 for a couple switches, including a service fee and $10 for wire connector? (The switches come with connector) Just a heads-up to others: be sure to ask detailed questions about hourly charges and how time will be managed, especially for smart device installations."

"I had an electrical issue in my kitchen and the power to main floor went out. I ended up having a back switch that needed to be replaced. I was quickly contacted to understand the issue, and DLP Electric was willing to come out today, however I had already just hired a technician from another company to handle (right before I spoke to DLP). Having said that, DLP Electric was professional and very helpful, and I would hire them if I ever needed electric work performed in my house. Great customer service and very responsive."

Generator installations FAQs

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 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.

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
