We’re committed to providing a personalized service for each individual project we take on & look forward to building strong, long-term relationships with our clients and guarantee your satisfaction.

"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 Bianca.Zong@gmail.com Residential lamdlord, Boonton Township, Bianca Zong"

Generator installations FAQs

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

  • Portable generators with 1kW–7.5kW capacity: $500–$2,000

  • Partial generators with 9kW–20kW capacity: $2,000–$6,300

  • Whole-house generators with 22kW–48kW: $5,000–$18,000

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.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

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.

The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

  • Experience frequent or prolonged power outages

  • Work from home

  • Store a lot of cold food

  • Have a sump pump

  • Have a pump for well water

  • Use electronic medical devices

  • Live in a climate requiring heating or cooling
