"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

"10 reasons you should consider Ryan: 1. Ryan was very honest upfront with what materials he will use and what work he will perform 2. Due to pandemic and heavy snow in Feb, he accommodated the entire estimate process with photos and FaceTime for an unconventional setup involving new sub panel in my garage 3. He was courteous in answering all my (some naive) questions about the estimate 4. His price is not the lowest, but he used industry grade NEMA 14-50 outlet not the cheap ones 5. He submitted the permit for me (so that we won't have any potential code issues if/when selling the house) 6. He followed up when the permit was approved 7. He showed on time, worked efficiently, and finished the installation within 3.5 hours (2 days later) 8. He did everything he said he would do and used all the materials he said he would use 9. The installation passed the inspection with flying color (inspector commented that "whoever did this did a neat job") 10. Last but not least, he is trustworthy and only took full payment after the pass of the inspection (no other HomeAdvisor contractors provided that kind of peace of mind) and provided one year of warranty on workmanship upon my request (which showed his confidence in his work and which I hope never have to use) => If you live in (central) NJ and need to install a home charging station for EV or PHEV, please don't decide on any contractor w/o getting an estimate from Ryan as well (even if with FaceTime)."

Generator Install questions, answered by experts

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.
