"I recently had a whole-house generator installed by Nick and his crew. I must say it was a pleasure dealing with this company, from the office staff to the installers. Everyone was so accommodating and mindful of my concerns and requests. The parts and tools they brought took up half of my back yard but at completion of the job, which took a full day, everything was removed and all my planters and other things were put back as before. A very seamless operation indeed. I would not hesitate to recommend LT generators."

"Gary was the only bidder who came to the house to review the project with me. This gave me confidence that he completely understood the scope and would not hit me with change orders. His price was competitive. On the day of installation, he and his assistant (required because I needed a new cable pulled between the house and detached garage) were courteous and professional. Once the charger was installed, Gary walked me through setting up the application to confirm I had set it up properly. Gary scheduled the LADBS inspection and returned to attend the inspection. Gary is knowledgeable, trustworthy, and friendly. I would absolutely use him again for other electrical projects."

"I am just so super extremely happy with the quality of work done, no doubt exceeded my expectations. It was a challenging install to get it from the panel through up the wall, over the roof and then through the attic into the garage, about an 80 foot run. I’m extremely particular about clean minimalist aesthetics to match the modern home we have. Such beautiful work, looks like it was designed for the home. Honestly can’t wait to work with Bumblebee for future projects. His commercial experience really shines through."

"They were very responsive. The owner of the company was here the day after we called to inquire, and we liked his answers to all of our questions. We made an immediate decision to hire them to install a 'stand-by' generator. First, the delivery of the generator was amazingly fast and then the installation was done promptly and professionally. There were enough people here to complete the installation. Within a few days a stucco repair man was here to patch the necessary holes. All-in-all, the overall service, responsiveness and professionalism were of the highest standards. I highly recommend Mr. Ariel Kahane and his crew of ADI Electrical Services."

Generator Install questions, answered by experts

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
