"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

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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.
