"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."

"Sergio and his assistant installed an EV charger at my place, and they did an amazing job. I’m so glad I hired them. Their price was reasonable compared to other contractors. I highly recommend them and would definitely use their company again for any future jobs."

"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."

"Everyone I dealt with was a delight. Competent, on time and efficient. While the true test of a new roof won’t be know until it rains, at the moment, I’m completely satisfied with the work that was done."

"Jose and team were amazing. The price was fair. The guys worked efficiently and clean. I couldn't be happier. They installed a Level 2 charger in my carport and added a main transfer switch to a location away from the main breaker box. We are very happy."

Generator Install questions, answered by experts

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

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. 

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
