"Two workmen showed up at the designated time and installed 'in wall' electrical for undercabinet lighting in the wall along with trouble shooting additional 3-way light switches, dimmers, and USB outlets. Work was fast, efficient, and professionally done within the allotted time. Would definitely recommend and will use Nasr Electrical again in the future."

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"Jeremy and his apprentice Kevin did an outstanding job. They were thorough, professional, polite, and explained the work being done throughout the job. Our house's electrical system was over 60 years old and not up to code or safe. Our fuse box was replaced with a new panel and breakers. The Pepco inspector remarked that Hyman's installation was one of the best installations that he has ever inspected. All of our outlets and switches were updated to meet code. The team found and resolved several problems that were serious safety issues. Our kitchen was upgraded so we could operate appliances without overloading the system. A line was installed to operate our air conditioner condensate pump directly and not from an extension cord. This was an expensive project and I know that I received the best service possible. I am very grateful to William Hyman Electrical for making our home safe."

"Since day one, Deybi and his crew have been able to solve any electrical problems I've had and provide efficient and effective solutions at a proactive level, long term result. First time working with them was due to our previous preferred electrical contractor failing to help with complex electrical problems at a commercial space (office space), so after some looking we found DBG Electric. They were able to help with setting up light switch wiring, installing cubicle receptacles and replacing fluorescent light ballast along with breakers. At another commercial site, we needed help with installation of power packs, emergency lights and flood lights. All of these were installed in a high ceiling area, which was no problem for DBG. They've also helped with lighting a my personal residence, ranging from kitchen light replaced with LEDs to recess lighting needed in the basement. I highly recommend using them, specially with difficult projects that require some ingenuity."

"It went great! Professional, quick to call and discuss the request. What I like the most was their genuine interest in helping me fast. They gave me an estimate the same day and the job was performed in less than 48 hours. I would definitely hire Green Electric for my future requirements. Thanks Mr. Darnell!"

"Our existing generator died. James diagnosed the problem and gave us a few options to repair or replace it. We chose to replace it. James handled everything, from getting and installing the new generator to electrical and fuel (propane) connections. We have asked him to schedule us for the annual maintenance on the machine. We are pleased, though we haven't lost power since it was installed, LOL."

FAQs for generator install projects in Olney, MD

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.

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 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
