"I cannot recommend RYB Electric LLC and Sebastian highly enough! We hired them for several electrical upgrades, including: 1. A full electrical panel upgrade 2, Installation of a Level 2 EV charger, and 3. Installation of ground rods for extra protection Beyond his technical expertise, Sebastian is a pleasure to work with. He is incredibly easy to talk to, has a great personality, and took the time to answer all my questions without making things feel overly complicated. It’s rare to find someone who is both a master of their craft and so personable. The workmanship is top-tier—everything is neatly installed, labeled, and functioning perfectly. If you are looking for a reliable, skilled, and fairly priced electrician who truly cares about the quality of his work, look no further than Sebastian. We couldn't be happier!"

"Frank and his team did a fantastic job upgrading our electrical panel and wiring for our generator. He even came out to help us during off hours when we needed help with starting the generator! He is quick to get back and does above and beyond. I highly recommend and will use his company again and again!"

"I cannot stress enough how impressed I am with their commitment to customers. After the installation of an outlet for an EV charger and an upgrade to my panel, I had a minor issue. Within an hour of me reaching out to inform them of the issue, I received a call with an offer from Endrite to come by later in the day to take a look. The repair was done at my convenience with no additional charge. They were thorough and went beyond what was probably needed to ensure the problem did not re occur."

"Greg the owner of Papa Grieves is an amazing, incredibly honest and dependable pool expert. He came to my house on Friday to repair my propane heater. The heater needed 2 parts and Greg only had 1 of the required parts on his truck. He called me, explained what needed to be done and that he would come back on Saturday to finish the job. Greg said that although the heater had a great deal of rust, he could fix it so that it would work for the remainder of the season. He did NOT try to see me a new heater, but I asked him what a new heater would cost. The price he quoted me was 20% less than what my current pool company, that did not return my call about my heater not working gave me at the beginning of the season. I asked him if he could install the new heater on Saturday, because I was having a big party on Sunday and he said the heater was in stock and that he could do the job the next day. Saturday morning the rain was coming down in buckets and I did not expect Greg to show up. But to my shock and amazement, at 10 AM the Papa Grieves Pool truck pulled into my driveway. In the pouring rain Greg and his assistant Raul removed the old heater and installed the new one. They performed all of this work without asking for a deposit or credit card for security. The heater works great. PARTY SAVED!!!!! That you Papa Grieves!!!!!"

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.

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

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
