"PERFECT / KNOWLEDGEABLE / EFFICIENT / HONEST would be the words I would use to describe LSVG Electrics. I had a circuit in the kitchen that was not getting any power even though the breaker in the main panel wasn't tripped so randomly picked LSVG Electrics for their assistance. Lou came out exactly at the time he said he would and quickly diagnosed the problem to be a burnt wire in a J-box in the basement and repaired it. If you are looking for an electrician that you can have confidence in ... please call LSVG Electrics ... because they know their stuff. I've only called electricians on a handful of occasions but LSVG electrics certainly was the BEST!!! and will use them for any other electrical issues I might encounter ... Highly Recommended ... 5 of 5 stars Regards, Keith K Algonquin IL"

"We recently had Priority Electric Solutions complete a panel upgrade at our home, and the experience was outstanding from start to finish. The electricians were professional, knowledgeable, and took the time to explain everything clearly before beginning the work. The installation was clean, organized, and completed on schedule. They made sure everything was up to code, answered all of our questions, and left the work area spotless when they were finished. It’s hard to find contractors who truly care about quality and customer service, but Priority Electric Solutions exceeded our expectations. If you’re looking for a reliable electrician, I highly recommend Priority Electric Solutions. Excellent service and workmanship!"

Generator Install questions, answered by experts

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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.
