"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."

"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."

"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."

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
