"The technician showed up timely.  He worked quickly to install the units we requested.  We had 4 sets of lights installed in two different segments of our basement.
The work was done within about 3 hours.  
My husband is happy with how fast and professional the technician was.  
The price was a little salty but that was our choice to spend the money because we just didn't have the time to do it ourselves.  
We are happy with the service and would recommended it for people that are similarly situated.  
I would call them again for future work.

"Francis, the owner, was a professional delight. Arrived on time, worked for hours, finished and cleaned up, and our dog accepted him as "belonging" in the house, even as he went in and out. He installed outlets in the front and back of the house (there were none when we bought this 1935 home) and changed the indoor outlets to grounded outlets. He was pleasant, thoughtful of the home, and patient with questions. A good hire and I would use him again. Thank you!"

Generator Install FAQs, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.

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.

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.

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
