"I came to know Obez Electrical through a friend's referral back in.2016. Bryant presented himself very confident, professional, well communicative and so organized! The year 2016's project was to split 2nd unit in a multifamily setting with a separate electrical pamel, rewiring the entire unit, Bryant responded my service calls whenever there is a need, that's why whenever I need eletrical work, my 1st instinct is reaching out Bryant first. This year 2023 the past week I need electrical work in a new bathroom, with permit and it needs pass town inspection. Bryant was able to get through the challenges, cuz sometimes while on the job running the wires inside the walls, electrician could be presented with a variety of problems. Bryant has strong problem solving skills on site, being attentive to detail. Bryant has very good time management. He performed the job quickly, along with good planning skills, pretty much the same time as he first came to estimate the job. Needless to mention that Bryant is so patient and he educated me the electrical codes, which gave me a clear picture of what the requirements are amd how to comply with, I believe when next week I go to town and talk to the town electrical subcode official, we can be on the same page and talk in the same language, highly appreciated! Sincerely wish Bryant big success with his ecpanding business in commercial and residential. He can definitely charm you with his superior expertise! Look no further! I endorse him! If you need further details before you hire him, I can always be reached at [email protected] Residential lamdlord, Boonton Township, Bianca Zong"

Generator Install questions, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

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

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
