"Just had them come and install some can lighting in my hall way that I wanted for some time now. They were able to remove my old fixture in the hall and install 4 new LED can lights, even installed the dimmer I wanted with it. Much appreciated!"

"Sparky?s Electric did an excellent job installing my EV charger. They were professional, knowledgeable, and showed up when they said they would. The installation was clean, everything was explained clearly, and they made sure everything was working properly before leaving. Pricing was fair and the quality of work was top notch. I would definitely recommend Sparky?s Electric to anyone looking for electrical work or EV charger installation."

"I had many things I needed upgraded around my house. I feel they were a bit ambitious with the time frame thinking everything could get done in one day. They had to come back the next day to finish up. They did a fantastic job with everything and didnâ t have any problem when my wife wanted a few more fixtures installed. Really good guys that do professional work. Price was lower than other bids I had as well."

Generator Install questions, answered by experts

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, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.
