"I hired Rob Heiser to install 7 new light fixtures and a post light on my home's exterior. He also installed a path lighting system and a brush box on the outside of my house to connect outdoor speaker cables to my Sonance system. Rob and his sons did an excellent job and were extremely professional. He performed the job exactly as I asked and did a great job cleaning and organizing all the removed fixtures and trash before they left. I would highly recommend Heiser Electric."

"I reached out to many companies for information on a whole house generator and Sparkie Electric was the first to contact me. They answered my many questions even before they came out to give me an estimate. After recommending which generator would be the best fit for my house, we set a date for the install. Sparkie Electric arrived on time and worked non-stop. I appreciated their efficient, knowledgeable work ethics. All of the men were courteous, friendly and answered all questions or concerns. I have already recommended Sparkie Electric to several of my friends. Not anxious for another power outage but feel confident that should one happen, my generator will 'save the day"!! Give Sparkie Electric a call today!!"

Generator Install questions, answered by experts

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

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. 

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
