"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."

"We hired ADI Electrical on 2/5/24 to do 5 different electrical jobs on our home, replace a fixture under the cabinet in the kitchen, supply and install floor outlet in the family room, supply and install new outlet for the garage ceiling, remove outlet in an old furnace closet, install new doorbell by move existing doorbell transformer to attic and fish ethernet cable from attic to junction box on side of house. Alvaro gave us a detailed estimate on 1/26 and we like their website which is very thorough and precise in its presentation. Michael the administrator in the office was very helpful in setting up appointments and anything else that was needed. Santo, Alex and Sam Adi came out on 2/6 to do the electrical work and we are extremely pleased with their attentiveness to detail and accomplishing everything that needed to be done. All the areas were cleaned up and everything was left spotless. We are very satisfied with the electrical services, and we highly recommend them."

"The two techs sent in to install my manual transfer switch did a great job. Instead of proposing crazy ways of installing the switch, they figured out how to do it without trying to upsell the project. Thanks"

"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

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.
