"I have been looking for a reasonably priced generator repair company for some time. The person who answered the phone was extremely courteous and seemed to go out of her way to help me with my service needs. Within 30 minutes the owner called back and based on my description of the problem was able to suggest a simple fix over the phone that I could do and which solved my problem. I will definitely call them for all my future needs."

"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"

"I'm very satisfied with his work. I had used him for 16 years and I had him install two different generators. I never had any problems at all and he is very responsive; that is why I have recommended him before."

Generator Install questions, answered by experts

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. 

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.
