"Nasr is wonderful! His guys did a great job with the panel which was old and as it turned out, replaced just in the nick of time as there were melted parts inside that could have started a fire! The wrong surge protector was installed so Nasr came back to put in the correct one. He is very friendly, communicative and easy to work with and does high quality work. I'm very happy with my new electrical panel."

"Ludwing did an amazing job! He installed a new light fixture in my home and what I appreciated the most was that he explained the connection to the wiring and how things work. This was very helpful because he corrected a job from a handyman who installed a light fixture that could have destroyed my home. He is a master of his craft. Not only will I use him for future projects but have also shared his contact with friends needing electronic assistance."

"The process from beginning to end was highly professional, technically very competent and complete, and the installation was impressive (Team of about nine people, all worked efficiently and simultaneously outside and inside my house. The job was done in a little over half a day. Very happy with my decision to hire GAC to spec, supply, and install the system."

"The RaLo electrician did a great job running new wire to install my outdoor camlight. He also informed me of a number of other issues he noticed and gave me good price to address those issues as well. I definitely recommend their services."

"The electrician did a quality job by relocating the light fixture; however, the actual charge was $195 or 65% more than the estimated price of $300. Owner refused to pay the extra $195 and the realtor had to pay it. Electrician also didn't replace two regular recessed light bulbs and the realtor would have to buy the light bulbs from Home Depot and installed himself."

"A+ Top notch service. Installing 1 attic fan, realized needed another one replaced. They went out, got a 2nd one and installed them both, plus gave advice on our under cabinet lights that always blink. Followed up the next day with a $15 solution to try before we do a repair. Good communication - they answer the phone when you call. Showed up on time and done in under 2 hours which included the time to get the 2nd fan."

This generator was installed on the side of a house.  The window had to be replaced to allow for the generator to be placed in this location.  The window was made to not open per code.
We installed this 14kW generator to power the whole house.  We used load shed modules to be able to save the customer money by using a smaller generator than would have been needed if we didn't use the load shed modules.

"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!"

"Kenneth was very professional. He was great with communicating how he was going to do the install. He showed up on time. Did the job and cleaned up behind himself. I would definitely recommend him to others. Great job!"

FAQs for generator install projects in Largo, 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
