"Very nice guys. They did great work, answered all my questions. I got my whole house rewired with very little disruption to my daily life. The owner took videos and pictures to keep my husband up to date on their progress and how to use our new generator. Very professional, small Christian company. I would recommend them and use them again if needed."

"“I recently had my electrical panel box upgraded and couldn’t be happier with the service. The electrician was punctual, professional, and clearly experienced. The installation was clean and organized, and they made sure everything met code requirements. They also answered all my questions and made the whole process easy and stress-free. I would absolutely hire them again and recommend them to anyone needing reliable electrical work.”"

"These young men were so professional and personable. They were honest and actually told us on several areas that we were just using the wrong type of light bulb, instead of charging us. I would highly recommend J & C, but please wait because I have more work for them to do and I want first dibs. 😀"

Generator Install FAQs, answered by experts

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.
