"I couldn't have asked for a better experience. They were hired to replace the main electrical panel/breakers at my elderly mother's home. Roni, the electrician, was a wonderful communicator, and was very knowledgeable and thorough in completing the job and in putting her at ease. The price was very reasonable. I will be using Nasr Electric in my own home, as well as recommending them to all my friends and family in the DMV area."

"I used them back in 2015 and was impressed with them. So I decided to use them again. I was quoted an hours worth of work. Then, when it came to the final bill, was charged for two hours worth of work, and this was with 2 men working the job. They were just replacing 3 pendant lights and 1 dining room light. So I was surprised and disappointed that it took that long. More importantly, one of the workers said something inappropriate to me. It made me feel very uncomfortable and afraid. So I called the owner to tell him what happened. He said he would speak to him. I felt like the owner could have taken me more seriously, been more sympathetic and apologetic about it. He made it sound like he was almost defending him. *** Update on this: The owner did speak with his crew member and said there was a misunderstanding of what he said and apologized for it. However, I know what I heard. Even to the end, it seemed like the owner was still defending him. Either way, I won't be using them again after my experience."

Generator Install questions, answered by experts

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
