"Glen and his team were prompt and professional during both installation and annual maintenance. We lost power during the last hurricane and the generator worked perfectly. Pricing was very good and Glen was even able to get me an extended warranty (promo from Generac). I would recommend Green Sun."

"Kope Electric just finished installing a Generac generator at my house and their work was top notch. They actually got me in their schedule 1 week early and finished as timely as they said they would. I highly recommend them to anyone interested in a generator."

"Roy is really a prof. He installed two overhead fans and a hanging lamp. The fans had a complicated control system but he was able to get them to work flawlessly. Bonus: he is really a nice person and he cleaned up too! I would recommend his work to anyone."

"Brian was awesome and fast and courteous. Princeton Electrical was easy to communicate and negotiate with, and offers a fair price for their labor. Had a Level 2 EV charger installed from my townhouse basement to my garage in a few hours without problems."

"A+ for being prompt, accurate on time and on the scope of work. I did request to install needed equipment to run the generator and my house had some non-standard situations. I love that all challenges were solved in the right way, not the fast way. The electrician was very open-minded for debating on the possible approaches to an unexpected situations, etc. I love the work, very rational pricing and I would hire again."

"We recently hired Spartan Home Pros for a multi-zone mini split installation, and they did an outstanding job from start to finish. A special shoutout to the lead technician, Charles—he was incredibly diligent, meticulous, and dedicated throughout the entire installation. ​Charles took the time to ensure every line was run cleanly, all wiring and line-hide covers were neat, and all manufacturer clearances and specs were strictly followed. They handled a tight installation spot upstairs with total professionalism and made sure everything was done right the first time. The team left the job site completely spotless, and having the system up and running with both heating and cooling working flawlessly is an amazing upgrade for our home. If you want true craftsmanship and honest, reliable work, I highly recommend Spartan Home Pros!"

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.

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.

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. 

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.
