"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!"

"Chris Boritz contacted me right after I requested a quote on Angie's List, I mean within a few minutes. He was punctual and quick when doing the estimate. He asked questions and talked to me for a few minutes to determine the easiest way to do the install and get me the outcome I wanted. The installer arrived a few minutes early. He was professional and friendly. At the end he cleaned up after himself. My only complaint was it took Chris a long time to get me a quote. His quote was lower than the other quotes so I would have hired him right away. Apparently, I caught him going out of town."

"I had a complex list of electrical tasks, including the installation of a half dozen fixtures I already had and about the same number that I’d have to trust All In Electric to choose on my behalf. I was very impressed that All In Electric’s owner, Keith, met with me, listened carefully to my many requirements, and wrote them up in an accurate, detailed, and clear quote. I wanted different quotes on different parts of the job, partly because I had some uncertainty about the feasibility of certain parts of it, such as replacing pool lights that had short-circuited. Keith insisted on a single overall quote for the job, which I agreed to because I made a judgment call that he was a reasonable man and would make a good faith effort to fulfill his commitment to getting the job done. Sure enough, there were some unanticipated problems, as there often are on such many-item jobs with some inherent uncertainty. And although there were some price increases, they were reasonable and fair. At the end of the day, All In Electric did what it said it was going to do and did it competently and sometimes with more polish than I knew to request."

"On both appointments, the technicians (David the first time, Matt & Evan the second time) were respectful and honest, very well organized. And they arrived right on time. We had ceiling fans and recessed lighting installed. They kept the work areas clean. -Frank K., City of Gambrills. My wife and I are very happy with their work, and the jobs were completed in the quoted time, even early! Everything was well explained and questions were answered with the feeling that they weren't in a rush to leave until I was satisfied. We will call again for future jobs."

Generator Install FAQs, answered by experts

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.
